Most complete skeleton of 30 million-year-old dog discovered | University of Michigan News

My last blog post concerned a 210-million-year-old, gap-filling dinosaur from Zimbabwe that is helping palaeontologists to reconstruct the early evolution and dispersal of dinosaurs.

This post concerns another gap-filling fossil, although one from much closer to the present—just 30 million years ago. It is a remarkably complete skeleton of the early canid Mesocyon coryphaeus, one of the most complete pre-Ice Age canid skeletons yet found in North America.

This specimen fills a different sort of gap. Mesocyon coryphaeus, first named in 1879, is relatively common in the John Day Formation of Oregon, but it was previously known principally from skulls and teeth. Its postcranial skeleton—the bones behind the skull—had remained almost entirely unknown. The new specimen therefore fills an important anatomical gap in our understanding of how early canids moved, hunted and responded to the changing environments of Oligocene North America.

The fossil itself has had a curious history. It was collected during the late 1980s from land administered by the Bureau of Land Management near what is now the John Day Fossil Beds National Monument. Encased in a protective plaster jacket, it entered the monument’s collection after initially being mistaken for an oreodont—an extinct North American even-toed ungulate sometimes loosely described as resembling a mixture of sheep, camel and pig.

During the 1990s, the skull was separated from the surrounding rock for display, whereupon its teeth and cranial anatomy revealed that it was actually a canid. Park palaeontologists began exposing the remainder of the skeleton in 2012, but preparation continued intermittently for years. By the time the fossil was fully uncovered in 2022, more than 500 hours of painstaking preparation had been devoted to it.

University of Michigan palaeontologist Anne E. Kort, together with Jennifer Cavin of John Day Fossil Beds National Monument and Xiaoming Wang of the Natural History Museum of Los Angeles County, formally described the specimen in a paper published online in the Journal of Paleontology on 29 May 2026.

Known as JODA 3366, the specimen includes a complete cranium, an almost complete vertebral column in front of the sacrum, all the major limb bones and parts of both the forefeet and hindfeet. Only the tail and portions of the hands and feet are missing. It even preserves part of the baculum, or penis bone, establishing beyond reasonable doubt that the animal was male.

New Zimbabwean dinosaur species named by Museum scientist reveals Africa’s hidden history | Natural History Museum

It is gap-filling time again — not because palaeontologists have discovered some predetermined evolutionary “missing link”, but because another conspicuous blank on the palaeontological map is being filled. This time, the new evidence comes from Africa and concerns a dinosaur that lived about 210 million years ago, during the Late Triassic.

The discovery sheds new light on the early diversification and geographical distribution of dinosaurs, when they were still only a relatively minor component of terrestrial ecosystems. Over the following millions of years, they diversified into an extraordinary range of forms and became the dominant large land animals of the Jurassic and Cretaceous periods.

Gaps in the fossil record are, of course, eagerly seized upon by creationists desperate to find somewhere to insert their god. Their enthusiasm tends to diminish markedly whenever palaeontologists recover new evidence from one of those gaps. Each such discovery removes another supposed refuge for the ever-shrinking god of the gaps, so the evidence must be dismissed as misidentified, incorrectly dated or merely another example of “evolutionary storytelling”.

No matter how many gaps science fills, creationists continue to assure themselves that the next one will be different: that it will finally be the gap that science cannot investigate and into which their preferred creator can safely be inserted. Unfortunately for that strategy, palaeontologists continue to discover fossils, dating methods continue to improve, and previously neglected regions continue to be explored.

This latest discovery consists of a partial skeleton excavated from exposures of the Late Triassic Pebbly Arkose Formation on the shore of Lake Kariba in northern Zimbabwe. An international team of Zimbabwean, South African and British scientists has named the animal Musango matusadonaensis. The study was led by Professor Paul M. Barrett of the Natural History Museum, London, while the expeditions during which the fossils were collected were led by Professor Jonah Choiniere of the University of the Witwatersrand’s Evolutionary Studies Institute.

Musango was an early sauropodomorph — a member of the lineage that later produced the enormous, long-necked sauropods such as Diplodocus. Unlike those gigantic four-legged descendants, however, Musango was a relatively lightly built, predominantly bipedal animal. It measured an estimated 4.5 metres in length but weighed only about 222 kilograms. Its skull has not been recovered, so its diet cannot be established with certainty, although comparisons with related dinosaurs suggest that it was probably herbivorous or omnivorous.

The fossil record of early dinosaurs is extremely uneven. Europe, North America and parts of South America have been studied far more intensively than much of Africa, leaving large gaps caused not necessarily by the absence of dinosaurs but by the scarcity of sustained palaeontological exploration. Musango is only the fifth dinosaur formally named from Zimbabwe, following the description in 2024 of another sauropodomorph from the same formation, Musankwa sanyatiensis.

Phylogenetic analysis places Musango and Musankwa as close relatives within Unaysauridae, a group whose fossils are known from Africa, India and South America — landmasses that were then joined within Gondwana. Together, these discoveries support an emerging picture in which Late Triassic southern Africa contained several distinct ecosystems with their own dinosaur communities, rather than a single uniform fauna extending across the region. Africa was therefore not a peripheral spectator in early dinosaur evolution; its still-underexplored rocks may preserve crucial evidence about how dinosaurs diversified and spread before their later ecological dominance.

Creationism Refuted - Another Gap Closed with a 23-Million-Year-Old Fossil - Just as The Theory Of Evolution Predicted

Australia’s most diverse marsupial predators have been hiding their origins for millions of years

To a palaeontologist, a gap in the fossil record is an unanswered question and an invitation to keep looking. To a creationist, it is more often treated as a convenient space in which to insert a supernatural explanation. The difficulty for creationism is that scientists have an inconvenient habit of finding the missing evidence, whereupon the gap becomes smaller, the evolutionary history becomes clearer, and creationists must quietly move their supernatural explanation somewhere else.

A particularly neat example is provided by a paper just published in Australian Zoologist by Timothy J. Churchill, Michael Archer, Suzanne J. Hand and Roy M. Farman. As Churchill explains in an article in The Conversation, a handful of tiny fossil jaws from north-western Queensland has supplied a previously missing opening chapter in the evolutionary history of Australia’s most diverse family of marsupial predators.

The family Dasyuridae contains almost 80 living species, including Tasmanian devils, quolls, dunnarts, planigales and antechinuses. They range from insect-eaters weighing only a few grams to the much larger Tasmanian devil, and occupy environments extending from the tropical rainforests of New Guinea to Australian deserts, grasslands and alpine woodland. Yet, despite this modern diversity, their early fossil history had remained frustratingly obscure.

Molecular studies indicated that dasyurids had diverged from their closest relatives millions of years before the earliest unambiguous fossils then known. Almost all accepted dasyurid fossils were younger than about five million years, leaving what palaeontologists call a “ghost lineage”: a branch whose existence was indicated by evolutionary relationships, but whose earlier fossil representatives had not yet been found. The animal once thought to fill that gap, Barinya wangala, was subsequently shown to belong to an entirely different family of peculiar, probably snail-eating marsupials called malleodectids.

Creationists sometimes present such gaps as evidence against evolution, apparently assuming that unless every organism that ever lived has obligingly become fossilised, been exposed at the surface and been discovered, the evolutionary history can be dismissed. But incompleteness is not inconsistency. Fossilisation is rare, suitable rocks are unevenly distributed, and tiny, fragile animals are especially unlikely to leave recognisable remains. Evolution nevertheless predicted that earlier dasyurids had existed. The question was whether any of them would eventually be found.

The new species, named Miyumba chrisdickmani, is known from six partial lower jaws recovered from Early Miocene deposits in the Riversleigh World Heritage Area on Waanyi Country. It lived about 23 million years ago and probably weighed only about 30 grams, making it comparable in size to a modern antechinus or large dunnart. It is now the oldest confirmed member of Dasyuridae, extending the family’s recognised fossil history by more than five million years.

Its significance, however, lies in much more than its age. The teeth of Miyumba possess a particular arrangement in which the third lower premolar is smaller than the first and second. This appears to be a shared derived characteristic, or synapomorphy, identifying dasyurids as a natural evolutionary group. At the same time, Miyumba retains several ancestral dental features expected in an animal close to the base of that group’s family tree.

That combination is precisely what evolutionary theory predicts: an early member of a lineage should possess the defining innovations inherited by its descendants while retaining features inherited from more distant ancestors. It should not look exactly like a modern Tasmanian devil, quoll or dunnart because those specialised forms had not yet evolved. Nor should it be unrelated to them. It should display a mosaic of ancestral and newly evolved characteristics — and that is exactly what Miyumba does.

How Snakes Lost Their Legs - 80 Million Years Before 'Creation Week'

80-million-year-old snake fossil sheds light on why lizards lost their limbs and started slithering

Of all the primitive ‘just-so’ stories in Genesis, the tale of how the serpent was condemned to crawl on its belly must rank among the most transparently mythological. Having supposedly tempted Eve to eat the forbidden fruit, God curses the serpent to go on its belly and ‘eat dust’ for the rest of its life. Although the story never explicitly says that the serpent previously had legs, the curse plainly implies a change and has traditionally been understood as an explanation for why snakes slither instead of walking.

Like so much of Genesis, it begins with an observation familiar to its authors—snakes have no legs—and invents a magical tale to explain it. It is an ancient example of an etiological myth: folklore devised to explain why something in the natural world appears as it does, long before anyone had the evidence or intellectual framework needed to understand its real history.

Even as mythology, however, the story is strangely incoherent. Genesis itself does not identify the serpent as Satan but introduces it as the most cunning of the wild animals God had made. Nevertheless, this supposedly ordinary animal can speak, reason and somehow knows about a prohibition that God had given to Adam before Eve had even been created. The text makes no attempt to explain how it acquired either this knowledge or the power of speech.

More awkward still for anyone insisting that the story is literally true, the serpent’s predictions prove substantially more accurate than God’s warning. God tells Adam that he will die on the day he eats the fruit. The serpent tells Eve that they will not die, that their eyes will be opened and that they will become like God, knowing good and evil. They eat the fruit, their eyes are opened and they do not die that day. God then confirms that the humans have indeed become ‘like one of us’ in knowing good and evil. According to Genesis itself, Adam goes on to live for another 930 years.

On the most straightforward reading of the story, therefore, the serpent tells Eve the truth while God’s threat to Adam proves false. Later theologians have attempted to rescue the tale by inventing a ‘spiritual death’, or by claiming that Adam merely began to die that day, but neither qualification appears in the text. These are apologetic repairs added by people who can see the problem but cannot admit that the story’s authors created it.

Science, meanwhile, has uncovered a very different account of how snakes acquired their extraordinary bodies—one involving neither talking reptiles nor fruit, curses or human disobedience, but descent with modification over immense periods of geological time. Snakes are highly modified members of the squamate reptile radiation. Their ancestors progressively elongated their bodies, increased the number of vertebrae and reduced their limbs as different lineages adapted to particular ways of life. Their evolutionary history extends back at least to the Middle Jurassic, about 160 million years ago.

Now, a paper published in Nature by an international team led by Tiago R. Simões describes an exceptionally well-preserved early snake from the Late Cretaceous of Brazil. Named Tametara mirim, the animal lived approximately 85–75 million years ago, when non-avian dinosaurs still dominated terrestrial ecosystems. It is the first articulated snake fossil known from Brazil and preserves a three-dimensional skull together with more than 100 connected vertebrae.

The preserved portion of its skeleton appears to have lacked forelimbs. Because the region around the pelvis is missing, the researchers cannot determine whether it retained vestigial hindlimbs, as some other early snakes did. Its skull also combines recognisably snake-like specialisations with ancestral features resembling those of other squamate reptiles—precisely the sort of mosaic of old and new characteristics expected in an evolving lineage, but not from the instantaneous transformation of an animal by a divine curse.

How Evolution Works - Shell Shock For Creationists

Empty seashells became new habitats 470 million years ago | University of Tartu

A paper just published in Scientific Reports by an international team led by Olev Vinn of the University of Tartu, Estonia, provides a lovely illustration of the opportunistic nature of evolution.

Some 470 million years ago — almost 470 million years before creationists’ mythical ‘Creation Week’ — a seemingly modest ecological innovation occurred in the oceans: animals began using the sheltered interiors of empty mollusc shells as habitats. This happened during the Middle Ordovician, following the Cambrian radiation, and helped to establish a new ecological niche that remains important in marine ecosystems today.

Creationists like to misrepresent the Cambrian radiation as the sudden appearance of complex, multicellular animals without ancestors. In reality, it was neither instantaneous nor without an evolutionary prehistory. It unfolded over tens of millions of years and grew out of changes already under way among the preceding Ediacaran biota, including increasing mobility, burrowing and ecological interaction.

As animals became more mobile, predation intensified and defensive structures became increasingly advantageous. Mineralised skeletons and shells evolved independently in several lineages, probably under several interacting pressures, including protection, structural support and changing ocean chemistry. Molluscs were among the groups that acquired shells, and their subsequent diversification produced such familiar forms as gastropods, bivalves and shelled cephalopods.

One consequence was the growing accumulation of empty shells on the seabed. Each dead mollusc left behind a hard surface and a sheltered cavity that other organisms could potentially exploit. Yet the researchers found that, throughout the Cambrian, the interiors of mollusc shells and other skeletal remains remained free of encrusting animals, even though organisms capable of living on surfaces inside other cavities already existed.

That changed during the Middle Ordovician, when attached animals began colonising the relatively large, spacious shells of nautiloid cephalopods. They later spread into the empty shells of gastropods and bivalves. No foresight or planning was required: once organisms capable of settling inside these shells gained access to a protected surface supplied with food-bearing water, any heritable tendency that improved their ability to exploit it could be favoured by natural selection.

Refuting Creationism - Death More Than 66 Million Years Before Mythical 'Sin'

"The Bite"

Rare fossil at Montana State’s Museum of the Rockies records Tyrannosaurus attack

A paper published on 17 February 2026 in PeerJ by Taia C.A. Wyenberg-Henzler of la of Montana State University, USA, reports on a remarkable fossil from the Hell Creek Formation of eastern Montana: a nearly complete, articulated skull of an adult Edmontosaurus annectens with the broken tip of a tyrannosaur tooth still embedded in its left nasal bone.

The fossil dates from the closing stages of the Late Cretaceous, roughly 66 million years ago, shortly before Edmontosaurus, Tyrannosaurus and all other non-avian dinosaurs disappeared during the Cretaceous–Palaeogene mass extinction. The bone surrounding the embedded tooth shows no evidence of healing or remodelling, indicating that the bite occurred at, very near or shortly after the death of the Edmontosaurus.

In other words, this is physical evidence of a violent interaction between predator and prey tens of millions of years before humans existed—precisely the sort of evidence that creationists are conditioned to reject because it cannot be accommodated within their mythology. According to young-Earth creationism, there was supposedly no death, predation or suffering before human ‘sin’ allowed evil to enter the world and ruin their omnipotent creator’s previously perfect creation—apparently without that omnipotent creator either foreseeing or preventing it. And all this supposedly happened only 6,000–10,000 years ago, shortly after ‘Creation Week’.

The doctrine that no animal died before ‘the Fall’ is not stated explicitly anywhere in the Bible. It is a theological inference imposed upon the text because young-Earth creationism requires it. It belongs to the category of reasoning that says: ‘This must be true for the rest of my beliefs to be true; my beliefs cannot be wrong; therefore, this must also be true.’

Having granted themselves this assumption of infallibility, creationists must then protect it from every fact that contradicts it. The belief cannot be mistaken, so the evidence must somehow be misunderstood, fraudulent, planted by Satan, created with the appearance of age or otherwise unworthy of consideration. Anything, in fact, is preferable to the intellectually honest admission that the belief itself has been falsified.

In almost every other field of human endeavour, such a supremely arrogant claim to personal infallibility would be laughed at and its proponent told to grow up. Yet, when packaged as religious faith, it is not merely tolerated but frequently treated with respect. Its advocates demand—and often receive—special privileges and social status: ‘You must listen to me, allow me to make laws governing your life and let me shape society according to my beliefs because I have an invisible friend and wear special robes.’

And so creationism staggers on, obliged to deny a veritable deluge of scientific evidence rather than concede that its mythology bears no resemblance to the history of life on Earth.

Creationism Refuted - Earth Is 'Fine-Tuned' For Disasters And Mass Extinctions

Researchers confirm cause of Earth’s biggest mass extinction | Stanford Doerr School of Sustainability

Studying the metabolism of living brachiopods like these collected from San Juan Island, Washington, allowed Stanford researchers to understand how the physiology of the modern fauna and Paleozoic fauna may have differed and how these groups would have been differentially impacted by oxygen and temperature changes during the Permian–Triassic mass extinction.

Many of Earth's climatic, geological and biological processes behave as complex, nonlinear systems, resembling systems in chaos. In this context, “chaotic” does not mean random. It means that small differences in starting conditions can sometimes be amplified until they produce very different outcomes — the phenomenon popularly known as the “butterfly effect”. The butterfly is not literally responsible for a distant storm; it merely illustrates how a tiny disturbance can cascade through a sufficiently complex system.

This is not the picture of a planet engineered to remain permanently benign or perfectly “fine-tuned” for life — still less for human life in the United States. Earth is habitable, but its habitability is contingent and sometimes precarious. The same interacting atmospheric, oceanic, geological and biological processes that sustain life can, when pushed beyond critical thresholds, drive abrupt environmental change, ecological collapse and mass extinction.

At several points in Earth's history, reinforcing feedbacks have transformed relatively small initial disturbances into rapid and profound environmental changes. Organisms adapted to the previous conditions were then confronted with combinations of heat, cold, acidification, oxygen loss or other stresses occurring too quickly for most populations to adapt. The result was widespread extinction.

What has been less well understood is why some groups were devastated while others living in the same changing environment survived. This is an important question for us because every organism alive today is descended from lineages that somehow survived every previous mass extinction.

Research by a Stanford University-led team, recently published in the Proceedings of the National Academy of Sciences of the United States of America (PNAS), now offers an experimentally supported explanation for one of the most striking patterns associated with the end-Permian mass extinction — the “Great Dying” of about 252 million years ago.

Creationism Refuted - Giant Kangaroos In New Guinea - 1,500 Years Before 'Creation Week'

Giant kangaroos survived until 6,500 years ago on the New Guinea coast.

It is probably fair to say that no branch of science is a friend of creationism. That is presumably why creationists devote so much time and effort to trying to discredit science—often without the slightest appreciation of the irony of using computers and the Internet, both products of science and engineering, to tell the world that science does not work. Yet their attitude towards science is not merely hostile but opportunistic: whenever they encounter a scientific finding that they think can be misrepresented as supporting creationism, they suddenly become jubilant champions of ‘the evidence’.

Archaeology is one of the most persistent threats to literalist creationism. Far from confirming the biblical narrative, it repeatedly uncovers evidence of human cultures, environmental changes and extinct animals extending far beyond the few thousand years permitted by Young Earth Creationism. Nor does archaeology stand alone. Its findings repeatedly converge with those of genetics, palaeontology, geology and climatology to produce the same coherent history—a history in which neither a recent magical creation nor a global genocidal flood leaves the slightest trace.

True to form, a recently published paper in the journal npj Biodiversity, by an Australian-based team of archaeologists and palaeontologists, presents evidence from New Guinea that simply could not exist if the biblical narratives of a magical creation a few thousand years ago, followed by a global flood about 4,300 years ago, bore any resemblance to reality. The evidence indicates that a large extinct kangaroo relative—probably Protemnodon tumbuna—survived on the northern coast of New Guinea until the Middle Holocene, perhaps as recently as about 6,500 years ago.

This was tens of thousands of years after every known species of Protemnodon had disappeared from Australia, where the genus is thought to have become extinct by about 41,000 years ago, along with most of the continent’s other megafauna.

Protemnodon tumbuna was a stocky, muscular forest-dwelling kangaroo weighing an estimated 50–90 kilograms—roughly comparable in size to a modern red kangaroo. Unlike modern large kangaroos, however, it was probably predominantly quadrupedal, using its powerful forelimbs to move through dense forest and hopping only inefficiently and for short distances, if at all. It was one of seven currently recognised species of Protemnodon known collectively from Australia and New Guinea.

Refuting Creationism - Population Collapse And Migration in Neolithic Europe - And No Evidence Of A Genocidal Flood

The researchers have conducted DNA analyses of the skeletons from a burial site like this one in France and found traces of several different diseases.

Stone age population collapse revealed by DNA study in France – University of Copenhagen

A paper published in Nature Ecology & Evolution by a large international team led by researchers at the University of Copenhagen, reports evidence that simply should not exist if the Bible creation myth, and its later global genocidal flood myth, had any basis in reality. The evidence shows a significant population collapse among Neolithic farming communities in what is now northern France about 5,000 years ago, followed by migration into the depopulated area by people with strong genetic links to southern France and the Iberian Peninsula.

The study is based on ancient DNA from 132 individuals buried in the allée sépulcrale at Bury, a large megalithic tomb about 50 kilometres north of Paris. The site was used during two distinct burial phases, separated by a hiatus associated with the wider Neolithic decline around 3000 BC. The researchers found that the people buried before and after this decline were not simply later descendants of the same local population, but belonged to largely discontinuous genetic groups. In other words, this was not merely a change in burial custom; it was a major population turnover.

The problems this presents for creationism are multiple. First, there is the evidence of established farming populations in northern Europe at a time when, according to Young Earth Creationist chronology, the world had only recently been magicked into existence. Secondly, there is the embarrassing survival of archaeological and genetic evidence which, under the same mythology, should either have been destroyed in a global flood a few centuries later, or buried beneath a distinctive, worldwide layer of fossil-bearing flood silt — a layer which is conspicuous by its absence. Thirdly, there is the evidence that the human population of Europe had already diversified into regionally distinct genetic populations by about 3000 BC, with enough structure for ancient DNA to distinguish northern French and German-like Neolithic farmers from later migrants with strong southern French and Iberian affinities.

None of this, of course, will cause creationists to reconsider the mythology. We can confidently predict that it will instead be treated as another test of faith: one more opportunity to demonstrate the strength of their determination never to let evidence change their minds. In creationist apologetics, refusal to learn is often mistaken for intellectual victory. The more compelling the evidence, the greater the achievement in ignoring it.

The reason for the population decline is not yet clear. The human remains contained genetic traces of pathogens, including the plague bacterium, Yersinia pestis, and the louse-borne relapsing fever bacterium, Borrelia recurrentis, but the evidence does not support plague as the sole cause of the collapse. The more likely explanation is a combination of disease, environmental stress, demographic disruption and social breakdown. Earlier burials contained multiple generations from the same extended families, suggesting stable, kin-based communities. Later burials were more selective and were dominated by a single male lineage, indicating a marked change in social organisation after the population turnover.

This adds to the growing picture of the so-called Neolithic decline as a widespread phenomenon affecting much of northern and western Europe, not just Scandinavia and northern Germany. It also offers a plausible explanation for the abrupt disappearance of megalithic tomb-building and other monumental traditions across parts of Europe at about the same time. The people who built those monuments did not merely change their minds about architecture; in places such as the Paris Basin, the population itself appears to have collapsed and been replaced.

Ancient Fire Record Rewritten: Researchers Push Earliest Evidence of Human Fire Use Back to over a Million Years | EUROPEAN FRIENDS OF THE HEBREW UNIVERSITY

A recent paper in PLOS ONE, by an international team including Dr Liora Kolska Horwitz of the Hebrew University of Jerusalem, reminded me of a quote by Francis Collins, former director of the Human Genome Project and founder and president of The BioLogos Foundation, which aims to reconcile Christian theology with science. It also reminded me how Young Earth Creationists traditionally cope with information that refutes their beliefs. The paper reports evidence for the use of fire in a South African cave by early hominins between 1.07 million and 1.79 million years ago — a fact entirely inconsistent with Young Earth Creationism (YEC).

This image of God as a cosmic trickster seems to be the ultimate admission of defeat for the Creationist perspective. Would God as the great deceiver be an entity one would want to worship? Is this consistent with everything else we know about God from the Bible, from the Moral Law, and from every other source—namely, that He is loving, logical, and consistent?

Thus, by any reasonable standard, Young Earth Creationism has reached a point of intellectual bankruptcy, both in its science and in its theology. Its persistence is thus one of the great puzzles and great tragedies of our time.

Francis Collins - The Language of God

In this quote from The Language of God, Francis Collins is referring to those Young Earth Creationists who dismiss the palaeontological, archaeological and cosmological evidence for life evolving on an old Earth in an even older Universe, as evidence deliberately created by God to test the faith of believers. Creationists also routinely dismiss this sort of evidence either by accusing scientists of faking it, or by attributing it to the work of Satan.

All of these are, of course, variations on conspiracy thinking — more understandable in a teleologically thinking toddler than in an adult. When it persists into adulthood, it is consistent with the findings of a psychology research paper which found that creationism and conspiracism share a common teleological bias: the tendency to explain events and natural phenomena as though they exist for a purpose, or are directed towards some hidden end. It is therefore no surprise that creationism so often depends on conspiracism. The surprise is that there are still so many people, especially in parts of the USA, who try to understand the world around them using a cognitive habit most children eventually learn to leave behind.

Creationism Refuted - Our Ancestors Lived In North America - 56 Million Years Ago

Life reconstruction of Teilhardina

Our primate ancestors evolved in the cold – not the tropics

At times, it seems almost cruel to keep reminding creationists that another day, another week and another month have passed, and still there is no hint that biomedical scientists are about to abandon evidence-based evolutionary biology and adopt magic-based creationism as a better explanation of the facts. And yet here we are again: another paper, another article, and another example of evolution providing the rational framework for interpreting the evidence.

And, to rub salt into creationist wounds, the evidence deals with events around 56 million years before creationists’ mythical “Creation Week”. As though to refute yet another creationist myth — that scientists are only allowed to publish papers that confirm mainstream scientific orthodoxy — the findings, published by Jorge Avaria-Llautureo of the University of Reading and colleagues in the mainstream journal Proceedings of the National Academy of Sciences of the USA (PNAS), challenge the long-standing assumption that the primate lineage originated in warm tropical forests.

The study maps the likely geographic origins of our primate ancestors and reconstructs the historical climate at those locations. Its conclusion is surprising: early primates appear to have lived, dispersed and diversified through cold, arid and temperate regions, not primarily in the tropics. Their later colonisation of tropical regions took several million years and seems to have been driven more by local changes between dry and wet climates than by global warming itself.

One useful example is the tiny early primate Teilhardina, a small, tree-dwelling mammal known from fossils around 56 million years old — roughly 10 million years after the extinction of the non-avian dinosaurs. Fossil evidence suggests that Teilhardina had nails rather than claws, helping it grasp branches and handle food, a characteristic associated with primates. Species of this early primate group appear in the fossil record of North America and then dispersed rapidly across what are now Europe and China.

An article explaining the finding and its significance for understanding our evolutionary origins was published in The Conversation by Jason Gilchrist, a lecturer in the School of Applied Sciences at Edinburgh Napier University. His article is reprinted here under a Creative Commons licence, reformatted for stylistic consistency:

UP News - University of Potsdam

A paper just published in iScience should, if they were aware of it, at least cause an honest creationist to question some basic assumptions. It reports that modern European fallow deer, Dama dama, retain only a fraction of the genetic diversity present in their Ice Age ancestors. This finding is based on ancient DNA recovered from the fossilised remains of ten, approximately 120,000-year-old fallow deer from Neumark-Nord in Germany, analysed by researchers from the University of Potsdam, the MONREPOS Research Center and Museum in Neuwied, and Leiden University in the Netherlands.

Creationism continues to take a battering in the world of real science, where yet another paper quite incidentally refutes several of its basic dogmas. Creationists, who are notoriously reluctant to read serious science and would probably struggle to understand it if they did, will no doubt remain blissfully unaware of this constant refutation of their core superstitions.

To ensure that ignorance is maintained, creationist disinformation sites expend considerable effort in spreading distrust of serious science amongst their followers. What cult leader would want his followers reading anything that exposes his claims as bogus?

However, ignoring the facts does not make them go away, and the facts this paper reveals go to the heart of creationist mythology. Firstly, this evidence should not exist at all if the Bible creation myth were real history: a magical creation just 6,000-10,000 years ago, followed by a catastrophic global genocide, would leave no room for a 120,000-year-old population of fallow deer preserved in an Eemian lake environment. Secondly, it undermines the creationist parody of evolution that they so often attack: the false claim that evolution must always mean increasing complexity, and that any loss of genetic information is invariably fatal.

The reduced genetic diversity of modern fallow deer is a clear example of evolution involving a loss of genetic variation within a population. So far as individual deer are concerned, there need be no immediate reduction in fitness; the problem comes when a population has less capacity to respond to environmental change, disease, or other selective pressures, and may then be more vulnerable to extinction. Evolution, of course, has no plan. Unlike intelligent design, or even guided evolution, it cannot foresee future conditions and prepare a species for them. A species can be driven towards extinction by the simple operation of mindless natural processes.

Exceptionally Well-Preserved Ant in Goethe’s Amber | Uni Jena

Some years ago, while staying for a few days in Berlin in a hotel just off Goethestraße, I made the mistake of telling a taxi driver that our hotel was just off “Go-eth Straße”. It took several minutes and a map to sort out the confusion.

“Nein! Goethe-Straße!” he laughed. Only then did I realise that “Go-eth” and “Goethe” were not two different German philosophers.

“Ach ja! Danke! Goethe! Ich bin ein Engländer!” I explained, in my best German.

“Ja! Is better we speak English,” he replied.

Goethestraße — Goethe Street — is, of course, named after Johann Wolfgang von Goethe (28 August 1749 – 22 March 1832), the German writer, poet, novelist and playwright. He was also an administrator, scientist, geologist, botanist and philosopher. As a naturalist and collector, he left behind an extensive geological and mineralogical collection, including 40 pieces of Baltic amber, which have now been closely examined by biologists at Friedrich Schiller University Jena — appropriately enough, since Goethe and the playwright Friedrich Schiller were friends.

What they found was the subject of a paper in Scientific Reports, published in January 2026. It is not good news for creationists, since it concerns an approximately 40-million-year-old ant, preserved in exquisite detail and now visible using modern imaging techniques such as synchrotron micro-computed tomography. In addition to the ant, the scientists also found a fungus gnat and a blackfly in Goethe’s amber.

It is unlikely that Goethe knew these creatures were preserved in his amber, since the pieces are unpolished and the contents are barely visible to the untrained eye. He certainly could not have known that the amber was tens of millions of years old. Had he known, we can only speculate how that knowledge might have affected his view of nature, time and human origins. His famous work, Faust, draws deeply on Christian motifs, including the story of a man who makes a pact with the Devil; but Goethe was also a serious observer of nature, living at a time when geology, palaeontology and evolutionary thinking were still in their infancy.

In the early nineteenth century, Europeans had not yet accumulated the overwhelming evidence that Earth is billions of years old and that life has changed profoundly over vast periods of time. Many educated people still interpreted history, nature and morality through a biblical framework, even when their own thinking was more subtle than simple literalism. Goethe, despite his scientific curiosity, lived before Darwin, before modern stratigraphy was fully established, and long before modern imaging could reveal the hidden contents of an opaque piece of amber.

Now, of course, we know better, because of the tremendous scientific progress made over the last two centuries.

There are only two things in the universe faster than light: monarchy and gods. When a monarch dies, the monarchy passes instantaneously to the sovereign’s heir, regardless of where either of them happens to be at the time; and when science shines a light into one of the gaps in which creationists have been hiding their god, the god has already departed. That, presumably, is why no god has ever been detected by science.

Creationist dependence on these god-shaped gaps has produced an ever-shrinking god as science fills one gap after another with evidence. The fallacy depends on the gamble that, unlike every previous gap closed by science, this one will turn out to require a supernatural creation event. It never does, of course, but that never seems to diminish creationist confidence that the next gap will be different.

True to form, science has now closed yet another gap with evidence, not magic. It is one few creationists are likely to know about, and fewer still would be willing to acknowledge, because it concerns a gap in the fossil record between the K–Pg mass extinction, which eliminated the non-avian dinosaurs 66 million years ago, and about 56 million years ago. In other words, it is a 10-million-year interval in the very long pre-‘Creation Week’ history of life on Earth — a history no self-respecting creationist can honestly admit exists without conceding that the Bible’s creation myth is not real history. Specifically, it is a gap in the fossil record of fish evolution, from the devastation at the K–Pg boundary to the later appearance of many species that look markedly different from those that preceded it.

That gap, known to palaeontologists as “Patterson’s Gap”, has now been partly filled by the discovery of the earliest known examples of six modern fish groups by a research team led by Sanaa El-Sayed, a University of Michigan doctoral student and researcher at the Mansoura University Vertebrate Paleontology Center. The fossils were found in the Qreiya 3 Lagerstätte, dated to 62.2 million years ago, in Egypt’s Eastern Desert. The discovery has just been reported in Science Advances.

Refuting Creationism - Wild Cattle Roamed The Grasslands Of Europe - 4 million Years Before Creation Week

Nowhere in the Bible will you find any mention of wild cattle roaming the land, nor any indication that domestic animals are highly modified descendants of wild species, reshaped by human selection because their wild ancestors were not conveniently suited to human use. Instead, we find the childish claim that all animals were created for the exclusive benefit of humankind — which raises the obvious question: did the creator not know what humans would later need, or did it simply get things wrong, leaving humans to correct the design by selective breeding?

This is easily explained once we recognise that the authors of Genesis had a narrow, parochial view of the world. They knew little or nothing of Earth’s history or of the origins of life on it, so they made up stories that conformed to their own cultural assumptions and superstitions, often borrowing from neighbouring cultures.

They were completely unaware of the rest of Eurasia beyond their limited view from the Canaanite hills, and equally unaware of the great age of the Earth or the cycles of glacial and interglacial periods that had characterised it for the previous several million years. Indeed, the concept of such deep time seems to have been far beyond their comprehension. They could therefore have had no concept of the early forms of cattle-like bovines that once roamed Europe, already fitted by evolution for life in the changing environments of the Pliocene.

One such animal was a large bovine species, weighing up to about half a ton, which lived in what is now north-eastern Iberia about 4.41 million years ago. The discovery and re-analysis of this animal has just been published in PLOS One by Leonardo Sorbelli of the Leibniz Institute for Evolution and Biodiversity Science, Germany, and colleagues.

The fossils, from the Camp dels Ninots site in Catalonia, include remains from at least 14 individuals, among them eight nearly complete and partly articulated skeletons. The species, Parabos tigneresi, helps fill a gap in the evolutionary history of Eurasian bovines, including the wider lineage that eventually gave rise to modern cattle, bison and buffalo. Although smaller than many living domestic cattle, these animals were larger than comparable bovids of their time, suggesting an early stage in the increase in body size that later became characteristic of the bovine lineage.

The researchers suggest that this increase in size may have been associated with the climatic and environmental changes that characterised Pliocene Europe. The anatomy of Parabos tigneresi also indicates an animal adapted mainly to humid, vegetation-rich environments, consistent with the reconstructed setting of Camp dels Ninots as a water-rich maar lake ecosystem.

This incidental confirmation of an earlier reconstruction of the lake ecosystem at Camp dels Ninots is a good example of how independent strands of evidence converge on the same conclusion. It also illustrates the strength of Darwinian evolutionary theory: organisms are expected to show adaptations to the environments in which they lived, rather than appearing as arbitrary, ready-made forms. In this case, the anatomy of these bovids is consistent with animals adapted to a humid, vegetation-rich lakeside habitat, exactly as the geological and palaeoecological evidence had already indicated.

Heron-like, fish-eating dinosaur from 70 million years ago discovered in Argentina - Taylor & Francis Newsroom

In my previous post, I wrote about Labrujasuchus expectatus, a bizarre distant relative of the crocodile line which walked on two legs, had tiny arms, and possessed a toothless mouth tipped with a beak. Although not a dinosaur, it looked superficially dinosaur-like — a neat example of convergent evolution. Because earlier and later shuvosaurids were already known from the region, palaeontologists predicted that a form occupying the gap between them should exist, and Labrujasuchus duly turned up in the right place and in the right rock formation.

That is how science works: evidence fits into a testable, predictive framework. Creationism, by contrast, has nothing to offer except hand-waving, misrepresentation and denial when confronted with a bizarre extinct archosaur from some 212 million years ago, just as it has nothing to offer in explanation of this almost equally bizarre dinosaur from about 70 million years ago.

The new species, Kank australis, is described by palaeontologist Dr Matías J. Motta, of the Bernardino Rivadavia Natural Sciences Museum in Buenos Aires (Museo Argentino de Ciencias Naturales “Bernardino Rivadavia”), and his colleagues in a paper published on 28 May 2026 in the peer-reviewed Journal of Vertebrate Paleontology.

Kank australis was a paravian theropod — an unenlagiid, belonging to a group of small- to medium-sized raptor-like dinosaurs known from Late Cretaceous Gondwanan deposits. Its discoverers suggest that it may have lived rather like a large heron. Its long jaws, armed with teeth, suggest a fish-eating habit, while its cervical vertebrae show structures associated with muscle attachment and the protection of neck blood vessels, features comparable with those seen in modern birds that rely on rapid, precise neck movements. In other words, this was probably not the familiar pop-culture image of a raptor as a fast-running terrestrial predator, but a specialised animal exploiting the riverine and wetland ecosystems of southern Patagonia.

And, as so often with new fossil discoveries, Kank australis fills in yet another of those gaps so beloved of creationists looking for somewhere to hide their ever-shrinking little god. In this case, it helps bridge a distributional gap in the Late Cretaceous record of southern Patagonia, connecting better-known unenlagiid records from northern Patagonia with those from Antarctica, and adding more detail to the still-patchy evolutionary history of these South American paravian dinosaurs.

New Species of Bizarre, Bipedal, Toothless Crocodile Relative from the Triassic Discovered | Natural History Museums of Los Angeles County

Evolution, proceeding without a plan and lacking any sense of direction, can produce some truly bizarre creatures which, despite their appearance, survived perfectly well in the environments in which they evolved. Indeed, it would be bizarre to suppose otherwise, given that natural selection favours those forms that work well enough to survive and reproduce over those less well fitted to do so. To suppose otherwise would rival creationism for irrationality.

In this post, I’ll deal with a bizarre distant relative of the crocodiles; in the next, I’ll write about a strange theropod dinosaur from 70 million years ago that comes close to what any creationist might imagine a transitional species between dinosaurs and birds should look like.

Creationism is, of course, itself the product of an evolutionary process, forced into ever more bizarre forms by the hostile environment of scientific evidence. Modern creationism has therefore, by a similar process, become almost as bizarre as the life forms it is forced to deny in order to survive.

The sad thing is that creationists are denied the wonder of the truth about our planet as revealed in increasingly astonishing detail by science, because the facts must be waved aside and denied in order to cling to the childishly simplistic belief in magic and a world full of evil conspirators diligently working to trick them into changing their minds.

Who, for example, could have predicted that a distant relative of the crocodiles walked on two legs, had tiny arms, and had a toothless mouth tipped with a beak? It is almost as bizarre as the mental gymnastics creationists need to perform to dismiss it and force-fit the evidence into the predetermined conclusion that it must have been magically created within the last few thousand years and then allowed to go extinct for no apparent purpose — or that the evidence must either have been forged, misinterpreted or planted to test or deceive us.

Nevertheless, this creature, Labrujasuchus expectatus, did exist about 212 million years ago, in the Late Triassic, and its description is the subject of a recent paper in the Journal of Vertebrate Paleontology. Its fossilised remains were unearthed in Late Triassic rocks at the Hayden Quarry, Ghost Ranch, New Mexico, USA, by a team of palaeontologists led by Dr Alan H. Turner of Stony Brook University, New York, USA, with colleagues including Dr Nathan D. Smith of the Natural History Museum of Los Angeles County, Los Angeles, California, USA.

To add insult to injury for creationists, this find fills one of those beloved gaps into which creationists try to force fit their creator god. The gap was that between two earlier discovered shuvosaurs from the region. It's discovery was thus a predicted by the Theory of Evolution, not by a book of Bronze Age mythology.

Refuting Creationism - The Fossil Record Confirms Evolution - And Falsifies Creationism

Fossil Trove Expands Range of Squishy Early Animals - American Museum of Natural History

A paper published on 20 May 2026 in Science Advances by a team of palaeontologists led by Scott D. Evans of the American Museum of Natural History, New York, very neatly illustrates the difference between evolutionary biology and creationism. It reports the discovery of a rich new Ediacaran fossil site in the Mackenzie Mountains of Canada’s Northwest Territories, containing fossils that appear earlier in the record, and in deeper-water settings, than current models of the Ediacaran biota had led palaeontologists to expect.

That is not a problem for evolution; it is how science progresses. Unexpected evidence does not destroy a scientific theory merely because it requires a refinement of detail. In this case, the discovery extends the known geographical, ecological and chronological range of part of the Ediacaran biota — the strange, mostly soft-bodied organisms that preceded, and helped set the stage for, the later Cambrian diversification of animal life.

When asked what would falsify the theory of evolution, the evolutionary biologist J.B.S. Haldane is said to have replied, “a fossil rabbit in the Precambrian”. He was making the simple point that evolutionary theory predicts a broad historical sequence: mammals should not appear before vertebrates, vertebrates should not appear before animals, and rabbits should not appear hundreds of millions of years before their ancestors. A genuine rabbit in Precambrian rocks would be an anachronism so extreme that it would call the whole historical framework into question.

But that is not what palaeontologists have found here. The newly reported fossils are not out of sequence; they are exactly the kind of organisms that belong in late Precambrian rocks. The surprise is not that they are in the wrong part of life’s history, but that some of them appear a little earlier, in a wider geographical range, and in somewhat different environments than previously recognised. In other words, the anomaly is chronological and ecological, not evolutionary.

To a creationist, of course, the question of falsification has to be avoided, because the honest answer is deeply uncomfortable. The fossil record as a whole does not show a sudden magical creation of all living things a few thousand years ago. It shows succession: organisms appearing, diversifying, changing and disappearing through vast spans of geological time. The dating of the rocks, using multiple independent geological and radiometric methods, consistently points to an ancient Earth and a long history of life, not to a recent creation week followed by a global flood.

That is why every such discovery is awkward for creationism but routine for science. Fossils are not distributed randomly, as they would be if all life had been created at once and then jumbled together in a recent catastrophe. They occur in a recognisable sequence, constrained by stratigraphy, radiometric dating, comparative anatomy, developmental biology and, for later organisms, genetics. The details are continually revised, but the broad pattern remains overwhelmingly consistent with evolution and wholly inconsistent with Biblical literalism.

By any honest application of the scientific method, that should be enough to falsify the creationist narrative beyond reasonable doubt. That it does not do so for creationists is not because the evidence is weak, but because the conclusion is protected from evidence. When the conclusion is sacred, facts become things to be explained away, misrepresented or ignored.

For evolutionary biologists, however, an unexpected fossil is not an embarrassment to be dismissed, but a clue to be investigated. If the evidence shows that part of the White Sea assemblage was present in Laurentia earlier than previously recognised, and in deeper-water environments, then the scientific response is to refine the model. The theory is not weakened by that process; it is strengthened, because it can absorb new evidence, generate better questions and produce a more accurate account of what happened.

The fossils described in this paper include more than 100 specimens, with several groups not previously recorded from North America, including Dickinsonia, Funisia, Kimberella and Eoandromeda. Some are estimated to be about 567 million years old, overlapping with the older Avalon assemblage and extending the known range of the White Sea assemblage by around 5–10 million years. The researchers also found that these organisms lived in deeper-water settings than had previously been recognised for this assemblage, supporting the idea that some early animal innovations may have begun offshore before spreading into shallower environments.

How Creationists Lie To Us - Ken Ham Shows Us His Cult Is For Fools Who Believe Lies

Tiny fossils found in 1.7 billion-year-old mud yield clues to the evolution of complex life.

The creationist Ken Ham’s website, Answers in Genesis (AiG), is notorious for the way it exploits the ignorance of its target readership and their eagerness for spurious “scientific” validation of evidence-free superstition. For example, AiG recently posted on X, formerly Twitter, asserting that the fossil record is “the graveyard of the global flood”:

The fossil record is the graveyard of the global flood. pic.twitter.com/1OWyNcEk5o

— Answers in Genesis (@AiG) May 20, 2026

What AiG does not say, of course, is that fossils are not found in a chaotic jumble, as would be expected from a single global catastrophe. They occur in a consistent geological sequence, with older rocks containing older fossil assemblages and younger rocks containing later ones. The succession is not random; it records changing environments, extinctions, radiations and evolutionary transitions over immense spans of time. The rocks themselves contain independent evidence of their age and origin — including stratigraphic relationships, geochemical signatures, volcanic ash layers where present, and other dating markers — and many sedimentary sequences accumulated gradually over thousands, millions, or even hundreds of millions of years.

Nor do fossil-bearing rocks show the global mixing that a planet-wide genocidal flood should have produced. Instead, they preserve organisms that lived in particular environments at particular times. Marine organisms occur in marine sediments; freshwater organisms in freshwater deposits; terrestrial organisms in terrestrial deposits. Local and regional faunas remain local and regional.

We do not find Australian marsupials randomly mixed through Cambrian marine deposits, nor African mammals churned together with Jurassic dinosaurs and Ordovician trilobites. If a flood had covered even the highest mountains, tearing up ecosystems across the planet and carrying bodies wherever the currents took them, that is exactly the kind of disorder we should expect. It is not what the fossil record shows.

So, far from proving there was a global genocidal flood just a few thousand years ago, fossils in sedimentary rocks demonstrate exactly the opposite. They record a long, ordered, localised and historically structured history of life on Earth. That history is not only incompatible with the childish flood myth promoted by AiG; it is one of the strongest lines of evidence for evolution over deep time. And that is probably why Ken Ham’s creationist organisation needs its followers to believe otherwise. The tactic is perfectly plain and deliberately dishonest: if the facts contradict your claims, misrepresent the facts.

Creationism Refuted - Australian Crocodiles Are Fatal To Creationism

129,000 years of crocodiles: what we know about Australasia’s ancient apex predators

According to Bronze Age Biblical mythology, existing species should have no ancestors because they were all supposedly magicked into existence fully formed during a few days of creation, just a few thousand years ago.

That childish belief has to be clung to by creationists despite the evidence of the real world, which tells a very different story: not of sudden manufacture, but of deep evolutionary history, extinction, replacement and survival. The iconic saltwater crocodiles of northern Australia provide a good example. They are not isolated products of a one-off act of creation, but living survivors of a much richer Australasian crocodylian history stretching back tens of millions of years, during which crocodile relatives occupied a variety of ecological niches, including those of formidable predators.

Modern Australia has only two native crocodile species: the freshwater crocodile, Crocodylus johnstoni, and the Indo-Pacific or saltwater crocodile, Crocodylus porosus. But the fossil and archaeological evidence shows that these are merely the remnant survivors of a once more diverse crocodylian fauna, including the now-extinct mekosuchines, a distinctive Australasian group whose members included species very unlike the crocodiles familiar today.

Now a group of researchers from the University of Queensland and Griffith University, together with colleagues from several other institutions, has pieced together the fragmentary evidence from 26 fossil and archaeological sites across Australasia to build a clearer picture of the crocodylians that once lived in the region, and of their interactions with humans. Their review of the evidence was recently published, open access, in the Zoological Journal of the Linnean Society.

The study shows that the late Pleistocene record of Australian crocodylians is still incomplete and often difficult to date securely, but it nevertheless reveals a lost diversity. The extinct mekosuchines appear to have declined and disappeared on mainland Australia around the same broad period as other Australian megafauna, while some survived much later on south-west Pacific islands such as New Caledonia, Vanuatu and Fiji. There, their remains occur in archaeological contexts, suggesting that they persisted until after human arrival and may have been affected by human activity.

Three of the authors have also written an article in The Conversation, explaining their research and its significance for understanding the evolutionary history of these reptiles. Their article is reprinted here under a Creative Commons licence, reformatted for stylistic consistency:
