New species of ancient crocodile named in honour of Welsh school teacher | Natural History Museum

A newly named, 215-million-year-old species of crocodile-like reptile, discovered in Gloucestershire, UK, and described in The Anatomical Record, looks rather like the sort of creature creationists imagine a transitional fossil should be: half of one modern species and half of another from an unrelated group. That, of course, is the ridiculous parody of evolution that the creationist cult teaches its followers to believe is what those crazy scientists think the Theory of Evolution describes.

In reality, this discovery is nothing of the sort. What it actually reveals is a species that raises interesting questions about the environmental pressures that shaped its evolution. It was a long-legged, fast-running crocodylomorph, resembling a greyhound with scales and a crocodile’s head and jaws. It probably lived its entire life on land, using its speed to hunt small animals. That, in turn, suggests its prey were also fast-moving, rather like the relationship between cheetahs and gazelles, which have co-evolved speed in an evolutionary arms race: one to catch fast prey, the other to escape a fast predator. It is exactly the sort of process that refutes the notion of intelligent design, yet is entirely predictable under the Theory of Evolution by natural selection.

This animal lived in what was then an area of high ground overlooking hot, arid plains during the Late Triassic. That was a period of major diversification, brought to an end by a mass extinction caused by intense volcanic activity. It was followed by the Jurassic, so comparing animals from before and after that extinction event can help us understand how life responded to those dramatic environmental changes. Among the creatures that survived were the ancestors of the dinosaurs, and later, birds and mammals.

The research team, led by PhD student Ewart H. Bodenham of University College London, with colleagues from UCL, the Natural History Museum, London, and the Staatliches Museum für Naturkunde Stuttgart, Germany, carried out a detailed analysis of this and other fossils from fissure deposits on either side of the Bristol Channel, in South Wales and South-West England. They concluded that this specimen represented a species new to science.

New pieces link fish puzzle – News

Today we have not one but two papers which together help fill a gap between the bony fishes and the first fish to venture onto land and evolve into the terrestrial tetrapods from which all land vertebrates subsequently evolved. It is a gap that presents creationists with a dilemma: it would have been a perfect god-shaped gap into which to insert their designer; however, it dates to some 410 million years ago, far too distant for their preferred timeline of 6,000–10,000 years, into which they need to try to compress the entire history of the universe.

One of these papers, just published in Canadian Journal of Zoology, is by a team from Flinders University, led by Dr Alice Clement, who have reassessed a mysterious fossil from the Late Devonian Gogo Formation in Western Australia using the latest technology, including CT scanning and computed tomography.

This work adds to our understanding of lungfish evolution from a key Australian fossil site that contains a diversity of lungfish fossils, including some poorly preserved specimens.

Meanwhile, Flinders University researcher Dr Brian Choo and colleagues at the Chinese Academy of Sciences, led by the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing, have described a new fossil, Paleolophus yunnanensis (‘old crest from Yunnan’). This team's work has just been published in Current Biology.

Paleolophus helps fill the gap between ancestral lungfish and their diversification a few million years later; in other words, it is one more example of the sort of transitional form that creationists insist does not exist: yet another so-called 'missing link'.

Analysis of 90-million-year-old fossil rewrites history | University of Minnesota

Many creationists believe the Theory of Evolution is primarily about fossils and that it predicts every stage in the evolution of a species should be present in the fossil record. From this misunderstanding comes the claim that any “missing link” falsifies the entire theory. The fact that palaeontologists have discovered yet another of those supposed “missing links” will therefore cause another bout of cognitive dissonance between what reality shows and what creationists insist reality ought to look like.

Creationists also traditionally deny that dinosaurs are evidence of an ancient Earth and of a mass extinction event 66 million years ago. Instead, they claim dinosaur fossils are normally found in sedimentary rocks because they were killed and buried during the Biblical Flood. This specimen, however, was rapidly buried and preserved by an advancing sand dune — something that is difficult to reconcile with the idea of a catastrophic global flood.

Its discovery was announced in a paper in Nature by a team co-led by University of Minnesota researcher Peter Makovicky and Argentinian colleague Sebastián Apesteguía. The paper describes the discovery of the complete skeleton of Alnashetri cerropoliciensis, a 90-million-year-old small dinosaur that fills an important gap in our understanding of where this group of dinosaurs originated and how they spread across the world.

Alnashetri belonged to a group of dinosaurs known as the alvarezsaurids, later members of which were characterised by their short, stubby arms and small teeth. Alnashetri, however, had longer arms and larger teeth, yet it was one of the smallest adult dinosaurs ever found in South America, weighing only about 4 pounds (around 2 kg). These primitive features and its small size show that the group became small before evolving their characteristic reduced arms and teeth. At 90 million years old, the fossil also suggests that the group originated on the supercontinent Pangaea before it fully fragmented, meaning their later global distribution reflects continental drift rather than migration across oceans.

Signs of Ancient Life Turn Up in an Unexpected Place | GSA News Release 26-02

Geologists led by Dr Rowan Martindale of the University of Texas at Austin, working with colleagues including Stéphane Bodin of Aarhus University, Denmark, have discovered strange crenulated structures in rocks in the Atlas Mountains of Morocco that reveal something unexpected about microscopic life 160 million years ago. Their findings are published today in the journal Geology. The evidence, plain to see in the rocks, should not exist if creationist mythology had any basis in fact.

The reality is that, during that vast span of Earth’s history before creationists imagine their god created the small flat world with a dome over it described in the Bible, something unusual was happening deep within marine sediments that later became the Atlas Mountains. Bacteria were forming microbial mats at least 160 metres below the sea floor, far beyond the reach of sunlight.

That alone is remarkable, but what makes the discovery particularly unusual is the distinctive ripple-like crenulations the mats produced. Structures like these are normally associated with microbial mats forming on the surface of undisturbed sediment. Such mats were common before the Cambrian Period, more than 540 million years ago, when complex mobile animals had not yet evolved to burrow through and mix the seafloor. In those earlier times, microbial mats could grow across the sediment surface and preserve delicate textures and ripples.

However, once burrowing animals proliferated during the Cambrian, the upper layers of marine sediment began to be constantly churned up in a process known as bioturbation. This destroyed microbial mats and prevented the formation of the characteristic surface patterns they once produced. For the last half-billion years these textures have therefore been extremely rare in normal marine sediments, appearing today only in limited environments such as very shallow waters where photosynthetic microbial mats can still establish themselves.

Yet the Moroccan rocks contain similar crenulated structures formed about 160 million years ago—hundreds of millions of years after burrowing animals had transformed the seafloor. The explanation is that these features formed not at the surface but deep within the sediment, where chemosynthetic microbes were able to grow undisturbed by burrowing organisms. Instead of relying on sunlight and organic debris, these microbes obtained energy from chemical reactions involving minerals in the sediment itself.

Far from supporting creationist assertions that life cannot arise from inorganic sources, chemosynthetic microbes have been exploiting chemical energy from rocks and minerals for billions of years.

Miniscule fossil discovery reveals fresh clues into the evolution of the earliest-known relative of all primates - Taylor & Francis Newsroom

Scientists have recently announced the discovery of a small tooth in the Corral Bluffs, in the Denver basin, Colorado that shows one of the group of early mammals from which primates later emerged probably evolved in North America. For Creationists keen to find a reason to dismiss science and the evidence it keeps revealing showing creationism is nothing but an evidence free superstition, this is eerily reminiscent of what they regard as the 'Nebraska Man' hoax.

The supposed hoax was nothing of the sort and was, in reality a creationists lie intended to mislead people, perpetrated by two evangelical Christian con-men, Hank Hanegraff and Grant Jeffrey, who falsely proclaimed it to have been a failed attempt to trick people into believing in evolution - a trick that still has some success on creationists, notorious as they are for failing to fact-check their claims.

Creationists like to pretend that palaeontology is little more than a catalogue of embarrassing mistakes and hoaxes. In reality, of course, the history of palaeontology shows the opposite: new discoveries steadily refine and improve our understanding of life’s history, filling gaps in the fossil record and clarifying evolutionary relationships. A recent discovery reported in a press release by Taylor & Francis and described in a peer-reviewed paper in the Journal of Vertebrate Paleontology is a good example of this process at work.

The discovery concerns a few minuscule fossil teeth belonging to Purgatorius, a tiny, shrew-sized mammal that lived about 65.9 million years ago, shortly after the asteroid impact that wiped out the non-avian dinosaurs. Purgatorius is widely regarded as one of the earliest known relatives of the primate lineage—the group that eventually gave rise to monkeys, apes and humans. Fossils of this animal were previously known mainly from Montana and parts of western Canada, but the new finds from the Denver Basin in Colorado extend its known range several hundred miles further south.

According to the researchers, this discovery helps fill an awkward gap in the early fossil record of primate relatives. Slightly younger species appear in the southwestern United States about two million years later, leaving palaeontologists wondering why earlier forms seemed confined to the north. The Colorado fossils suggest that these early primate relatives probably spread southwards fairly rapidly after the mass extinction that ended the Cretaceous Period, diversifying as forests recovered in the aftermath of the impact.

However, before creationists begin sharpening their pencils in preparation for another round of “Nebraska Man” rhetoric, it is important to understand what this discovery does—and does not—show. The paper is not claiming that primates themselves evolved in North America, nor that this tiny mammal was a direct ancestor of humans. Purgatorius is better described as a stem relative of primates—an early member of the broader evolutionary group from which primates eventually emerged. In other words, it sits near the base of the evolutionary tree leading to primates, not within the modern primate group itself.

What the discovery really demonstrates is something far more typical of evolutionary biology: as new fossils are found, the geographical distribution and timing of early evolutionary lineages become clearer. In this case, a few teeth barely larger than grains of rice are helping palaeontologists reconstruct how the earliest primate relatives spread across ancient North America in the chaotic ecological world that followed the extinction of the dinosaurs.

January: Bristol scientists discover early sponges were soft | News and features | University of Bristol

Creationists have a massive gap to try to close; a gap so wide it makes the Grand Canyon look like a mere ditch. It is the gap between the earliest signs of life in the fossil record and the timeline a literal reading of the Bible allows. And that gap just got a lot wider.

Creationists could once take comfort from the fact that there was little solid fossil evidence of multicellular life much before the Cambrian, when organisms with hard body parts that fossilise begin to appear in the record. That gap was closed, not by fossils as we normally understand the term, but by chemical fossils contained in ancient rocks, as I explained in my last blog post. This evidence, together with genetic evidence from other work, shows that the common ancestors of multicellular animal life were very probably sea sponges.

But to a creationist, conditioned to believe that the Theory of Evolution is a theory about fossils—so that any gaps in the fossil record must be fatal for the theory—there is still some comfort in the fact that whatever left these chemical fingerprints in ancient rocks left no tangible fossils.

Now a team of palaeontologists, led by the University of Bristol, have shown that the lack of fossil evidence of these ancestral sponges has a simple explanation: they were soft-bodied, having yet to evolve the characteristic skeletons composed of millions of microscopic glass-like spicules. These did not evolve until about 560 million years ago. The team have recently published their findings, open access, in the journal Science Advances.

The Bristol-led team have now pushed back the evolution of these soft-bodied sponges to between 615 and 600 million years ago by using a combination of genetic evidence from 133 protein-coding genes and fossil evidence. This approach also showed that the spicules evolved independently in different sponge groups by convergent evolution.

We have another example today of how the evidence written into the fossil record — which creationists insist either does not exist, or is at best a lie forged to deceive us — stubbornly refuses to conform to creationist requirements. Instead, it continues to tell the only story it can: of life evolving slowly over deep time on a planet that is billions of years old.

The latest example comes from a paper published in Nature Ecology and Evolution by researchers from the Field Museum of Natural History in Chicago, Carleton University in Ottawa, Ontario, Canada and the Smithsonian Museum. The study was co-led by Arjan Mann, assistant curator of fossil fishes and early tetrapods at the Field Museum.

The paper presents evidence of the earliest known herbivorous vertebrate — dating to some 307 million years before creationists believe the Earth was created. Once again, this highlights the fundamental problem creationists face when they begin with a dogmatic belief that the Earth is only a few thousand years old because a handful of Bronze Age pastoralists said so. Having declared in advance that there has been no significant evolution, only minor variation within “kinds”, they are then forced to twist and contort the real-world evidence in a futile attempt to shoehorn it into their absurdly compressed timescale.

The animal, named Tyrannoroter heberti by the researchers, evolved over the tens of millions of years since the first vertebrates transitioned from lobe-finned fish to terrestrial tetrapods around 375 million years ago — perhaps to escape aquatic predators, or to exploit the invertebrate prey that had already colonised the land. Plants, meanwhile, which had begun spreading onto land some 475 million years ago, had also been evolving, and by this time were well established as ferns, horsetails, and other tough early vegetation.

Tyrannoroter heberti, known so far from a single skull, was probably among the largest terrestrial animals alive at the time, reaching around a foot in length — roughly the size of an American football — based on the proportions of close relatives. The fossil was recovered from shoreline cliffs in Cape Breton, Nova Scotia, Canada.

It is thought to represent a stem amniote: part of the lineage of vertebrates that evolved the ability to lay eggs away from water, unlike amphibians which must still return to water to reproduce. This group ultimately gave rise to reptiles, birds, and mammals — in other words, to almost the entire later terrestrial vertebrate world, including ourselves.

Creationism Refuted - How The Fossil Record Tracks Climate Change

The climate in Catalonia was much rainier 10 million years ago - Universitat Autònoma de Barcelona - UAB Barcelona

A paper published a few days ago in the Journal of Mammalian Evolution describes how the climate in Catalonia was much wetter 10 million years ago than it is today, with rainfall roughly twice the present rate, and how this was reflected in the evolution of mammals in the region. The study was conducted by palaeontologists at the Institut Català de Paleontologia Miquel Crusafont (ICP-CERCA), in association with colleagues from the Universitat Autònoma de Barcelona (UAB).

This must be deeply frustrating for creationists because, no matter how much they ignore the evidence, misrepresent it, or shout abuse at scientists, the evidence stubbornly refuses to support creationism and invariably supports evolution over deep time on an ancient Earth. The findings presented in this paper are, of course, no exception.

Scientists have previously established a close link between rainfall and the composition of mammalian communities, with wetter conditions favouring insectivores. Increased rainfall promotes the development of forests, which in turn provide abundant niches for insects and other invertebrates—the primary food source of insectivorous mammals. This relationship between small mammals and climate was first studied in detail by Jan van Dam, an associate researcher at the ICP. Van Dam developed equations that allow both average annual rainfall and its seasonal distribution to be estimated from fossil assemblages of small mammals.

Building on that earlier work, the present study analyses the abundant fossil record of small mammals to reconstruct populations that changed dynamically through time in response to shifting climatic conditions—exactly as predicted by the Theory of Evolution. There is, unsurprisingly, no evidence of spontaneous creation of species, nor of a global biological reset caused by a genocidal flood a few thousand years ago.

Baby dinosaurs a common prey for Late Jurassic predators | UCL News - UCL – University College London.

The prolific-waste reproductive strategy of Late Jurassic dinosaurs has been highlighted in a paper published in a New Mexico Museum of Natural History and Science Bulletin by a team of palaeontologists led by Dr Cassius Morrison of University College London’s Department of Earth Sciences.

The team constructed a detailed food web using fossil data laid down around 150 million years ago in the Morrison Formation of the United States. The Morrison Formation is a prominent sequence of Upper Jurassic sedimentary rocks (approximately 156–147 million years old) spanning around 1.5 million square kilometres across the western United States. It is North America’s most prolific source of dinosaur fossils, preserving vast deposits of mudstone, sandstone, and limestone formed in ancient river systems and floodplains.

Their analysis revealed that a major food source for carnivorous dinosaurs consisted of the young of the largest herbivores. These animals followed a reproductive strategy in which large numbers of offspring were produced and then effectively abandoned after hatching. Such juveniles would have been abundant, vulnerable, and easy prey for predators. This strategy is a familiar one in biology and only makes sense as the outcome of evolutionary processes. As an intelligently designed reproductive strategy, however, it is difficult to make sense of at all.

This is yet another example of the prolific waste that characterises living systems and betrays the absence of intelligent foresight in their design. Prolific waste and unnecessary complexity are hallmarks of evolution, whereas minimal waste and minimal complexity are the defining features of genuinely intelligent design — a distinction I explore in detail in my book The Unintelligent Designer: Refuting the Intelligent Design Hoax.

Refuting Creationism - Blood Tests On Ancient Fossils - And What They Can Tell Us

Life in fossil bones: what we can learn from tiny traces of ancient blood chemicals

A paper recently published in Nature details the application of a new field known as palaeometabolomics to reconstruct ancient African environments and track how they changed over time.

Modern medicine can learn a great deal about our health and lifestyle from a blood test, because blood contains traces of metabolites derived from the food we eat, as well as indicators of liver and kidney function and how effectively metabolic waste is disposed of.

But what if we could perform blood tests on archaic animals and human ancestors? Over time, this could tell us not only what they ate, but how their diets changed, which in turn reveals changes in rainfall, temperature, vegetation cover — forest versus savannah — and the species that were hunted and consumed.

DNA from wolf pup’s last meal reveals new facts about woolly rhino’s extinction

A new research paper published in the journal Genome Biology and Evolution, by a team led by palaeogeneticists from the Centre for Palaeogenetics, Stockholm, Sweden, may make uncomfortable reading for any creationists with the courage to read it.

Firstly, it deals with events from that long period of pre-“Creation Week” history — evidence which would not exist if the biblical Flood myth were true. Secondly, it illustrates how, in contrast to the claim that scientists are only permitted to publish findings that conform to a rigid scientific orthodoxy, researchers are perfectly willing to revise established ideas when new evidence demands it. In this case, the study shows that one aspect of what palaeobiologists thought they understood about the evolutionary history of Eurasian megafauna may be wrong.

The Age of Fishes began with mass death | Okinawa Institute of Science and Technology OIST

A recent paper published in Science Advances by Wahei Hagiwara and Professor Lauren Sallan of the Macroevolution Unit at the Okinawa Institute of Science and Technology, Japan, closes a long-standing gap in our understanding of the early radiation of vertebrates into jawed and jawless fishes following the Late Ordovician mass extinction, around ~445–443 million years ago. Their analysis shows that this radiation arose from a small number of fortunate survivors clinging on in ecological refugia. From those few lineages, of course, all modern marine and terrestrial vertebrates ultimately evolved.

This study neatly dismantles one of creationism’s favourite rhetorical fallbacks: the claim that Earth was deliberately “fine-tuned” to support complex life, and ultimately humans. The evolutionary pattern revealed here—near-annihilation followed by recovery from a few scattered refugia—is not the signature of foresight or optimisation, but of contingency and survival against the odds. Life does not flourish because conditions are perfectly arranged for it; rather, whatever happens to survive is forced to adapt to whatever conditions remain. The history of vertebrates, like that of life more generally, is therefore not one of careful planning, but of repeated catastrophe followed by opportunistic evolutionary radiation.

Creationists are notable for clinging to demonstrably false beliefs in the face of overwhelming evidence, childishly mistaking stubbornness for intellectual strength, rather like a spoilt toddler refusing to accept that they have just lost a game of Snap!. Alongside the patently absurd claim that Earth is only 6,000–10,000 years old sits the almost equally untenable belief that the planet was created exactly as it is, perfectly suited for human life. This notion is maintained despite abundant evidence for repeated mass extinctions driven by cosmic impacts, large-scale geological processes such as plate tectonics and associated seismic activity, major reorganisations of ocean circulation, and delicately balanced biogeochemical feedback systems involving oxygenation and carbon cycling that periodically spiral out of control, triggering catastrophic climate change.

What the evidence actually reveals is not a cosy, well-regulated world resembling some tranquil small town in Kansas, but a planet that is frequently so hostile to life that much of it is wiped out entirely. Most species go extinct, leaving only a handful of survivors to inherit the aftermath and radiate into new forms adapted to altered conditions—until they too are eliminated by some future catastrophe. The conclusion is unavoidable: Earth is not fine-tuned for human life, or for life in general. Instead, today’s species are the fortunate descendants of a few lucky survivors, shaped by natural selection to fit available ecological niches as neatly as a hand fits a glove.

Metabolic Analyses of Animal Fossils Helps Scientists Reconstruct Million-Year-Old Environments

The bad news for creationism continues unabated. Scientists led by Professor Timothy G. Bromage of the Department of Molecular Pathobiology at New York University College of Dentistry have developed a technique that opens an entirely new window onto the deep past. By analysing metabolites preserved in fossilised bones, the researchers are able to extract detailed biological and environmental information from animals that lived between 1.3 and 3 million years ago.

The team have published their findings in Nature, describing a method that pushes palaeobiology well beyond traditional morphology-based reconstruction.

The significance of this technique lies in its ability to reconstruct ancient environments with remarkable precision. From the chemical signatures locked within fossil bone, researchers can infer temperature, soil conditions, rainfall patterns, vegetation, and even the presence of parasites. The resulting picture is one of ecosystems changing over time, with animals adapting in step with shifting environments — exactly what evolutionary theory predicts, and wholly incompatible with the childish notion of magical creation a few thousand years ago or a recent biological reset caused by a genocidal flood.

This paper will have creationists searching for reasons to dismiss evidence that would, if they were prepared to accept it honestly, force them to concede that their beliefs are wrong. It reports a discovery by researchers at Stellenbosch University showing that dinosaur eggshells can be dated with a high degree of precision using an already well-established technique: uranium–lead (U–Pb) radiometric dating.

Until now, U–Pb dating has been most famously applied to zircon crystals in volcanic ash, where the age can be determined by measuring the ratio of radioactive uranium isotopes to the stable lead isotopes produced by their decay. In this study, however, the same underlying principles are applied to calcite crystals preserved in dinosaur eggshells.

The scientists have published their method, open access, in the journal Communications Earth & Environment.

Apex predators in prehistoric Colombian oceans would have snacked on killer whales today: McGill study | Newsroom - McGill University

Two researchers at McGill University, Montréal, Québec, Canada, have uncovered evidence of an ecosystem teeming with giant marine predators some 130 million years ago. The largest of these predators could, quite literally, have eaten something the size of a modern orca as little more than a snack. This will make depressing reading for creationists, not only because it all happened deep in the long pre-“Creation Week” history of life on Earth, but because the evolutionary arms races that led to these giants are precisely what the theory of evolution by natural selection predicts.

The two researchers, Dirley Cortés and Professor Hans C. E. Larsson, have just published their findings, open access, in the Zoological Journal of the Linnean Society.

It doesn’t get any easier for creationists. Just because it’s Christmas week doesn’t mean the awkward facts are going to go away, or that scientists are going to stop uncovering more of them. No matter what they post on social media; no matter how loudly they shout; or how fervently they gather on Sundays to collectively drown out their doubts, Santa is not going to deliver evidence that the Bronze Age creation myths in the Bible contain even a grain of historical truth. The problem is that truth remains true whether a creationist believes it or not, and regardless of whether their parents believed it. No amount of looking the other way or pretending the facts aren’t there will ever change that.

The palaeontologists reached their conclusions by reconstructing an ecosystem network for all known animal fossils from the Paja Formation in central Colombia. They used body sizes, feeding adaptations, and comparisons with modern animals, and then validated the results against one of the most detailed present-day marine ecosystem networks available: the living Caribbean ecosystem, which they used as a reference. The Paja ecosystem thrived with plesiosaurs, ichthyosaurs, and abundant invertebrates, giving rise to one of the most intricate marine food webs known. This complexity emerged as sea levels rose and Earth’s climate warmed during the Mesozoic era, including the Cretaceous, triggering an explosion of marine biodiversity.

A New Global Discovery by Mansoura University's Vertebrate Paleontology Center - Mansoura University, Egypt

When scientists from Mansoura University, Egypt, recently announced in the Zoological Journal of the Linnean Society of London the discovery of an 80-million-year-old marine crocodyliform unearthed in Egypt’s Western Desert, the headlines hailed it as “the earliest known member of Dyrosauridae”, a forgotten branch of ancient crocodile-relatives adapted for coastal and marine life.

Found in mid-Campanian deposits of the Quseir Formation, Wadisuchus kassabi is represented by partial skulls and jaws from several individuals — enough to show that by this stage dyrosaurids already possessed the long, narrow snout and needle-sharp teeth suited for grabbing fish or turtles. What makes this find so important is not merely the age — though pushing the dyrosaurid fossil record back by several million years is notable — but the evolutionary implications and what it tells us about the scientific method. The cranial anatomy of Wadisuchus exhibits a transitional mixture of primitive and derived features: reduced premaxillary alveoli, modified jaw-occlusion patterns, and dorsally positioned nostrils for surface-breathing, reflecting a transitional form on the path from earlier crocodyliforms toward specialised marine dyrosaurids. Phylogenetic analyses consistently recover Wadisuchus as the basal (earliest-diverging) dyrosaurid — pushing the origin and early diversification of the family deeper into the Cretaceous.

This discovery underscores a fundamental truth of modern science: claims are not fixed dogma, but provisional explanations always subject to revision in the light of new evidence. Just as Wadisuchus reshapes our view of when and where dyrosaurids emerged, other fossil finds have repeatedly nudged back the origins of major vertebrate lineages, re-drawn phylogenetic trees, or revealed unexpected ancestral forms. In this way the scientific method resembles nothing so much as a continual conversation with Nature — a conversation always open to challenge, refinement, or outright contradiction when the data demand it.

Unlike creationists, whom recent research has shown, believe not changing their mind is a sign of strength of character and commitment to their 'faith', scientists know that the real test of character is a willingness to accept the evidence and the humility to allow it to dictate opinion.

Incidentally, it might come as a shock to creationists that a marine fossil was found in the Sahara Desert and that Earth was not created as it just a few thousand years ago, but has changed significantly over the millions of years, including periods of 'green Sahara'. As someone who has flown in a small plane over the Egyptian desert, I can attest to the existence of dry riverbeds and feeder streams in that desert, even though today rain is almost unknown in the vicinity of Luxor.

It’s Coelacanth time for creationist disinformers again.

Hilariously, I’ve known creationists claim that the 'fact' that coelacanths haven’t changed for 200 million years somehow proves the “evilutionists” are wrong and that Earth is only 6,000–10,000 years old. How they managed to examine the genome of a 200-million-year-old fossil remains a mystery, but DNA appears to play no part in a creationist’s definition of evolution.

So, for an alternative fallacious argument, here’s an even older fossil that’s still around today, apparently in much the same form as it was almost half a billion years ago. It’s a parasitic worm that attacks oysters. The details have just been published in the journal iScience by scientists led by University of California, Riverside palaeobiologist Karma Nanglu, with colleagues from Harvard.

The parasitic, soft-bodied bristle worm belongs to a group called the spionids. It’s common in today’s oceans and feeds on the shells of mussels and oysters, leaving a characteristic question mark-shaped track in their shells. Their parasitism doesn’t kill the shellfish but probably shortens their lifespan.

Creationism Refuted - Scientists Revisit Some Old Fossils, Extend Scientific Knowledge - And Casually Refute Creationism Again

296-Million-Year-Old Fossil Unearthed in Brazil Sheds Light on Ancient Plant Mystery Hidden for Over Half a Century - Notícia

In another of those regular events in science, a team of researchers led by the University of Vale do Taquari – Univates, Rio Grande, Brazil, through the Graduate Program in Environment and Development (PPGAD), re-examined material held in the Univates Palaeontological Collection. Using modern equipment that was not available when the fossils were first studied more than 50 years ago, they uncovered new information – and, without intending to, once again demonstrated the weakness of creationist claims. As usual, creationism is refuted by the evidence.

What the team discovered were plant spores preserved in situ in fossils dating to between 298.9 and 252.17 million years ago – long before dinosaurs appeared and well before flowering plants evolved. At that time, the most advanced land plants were spore-bearing, like today’s mosses and ferns. This showed that the original classification as Lycopodites was incorrect. Instead, the fossils belonged to a new genus, which the team named Franscinella, giving the newly described Upper Palaeozoic plant the species name Franscinella riograndensis.

The significance extends further: the spores, now positively linked to this species, are index microfossils found in Permian strata of the Paraná Basin. Yet creationists routinely dismiss the use of index fossils in geochronology as “circular reasoning.” The ability to tie these spores directly to a particular species undermines that objection and strengthens their role in stratigraphy.

Refuting Creationism - How Baby Pterosaurs Met Their Death - 150 Million Years Before "Eve's Sin"

The Bible hints at the notion that human death only entered the world through "The Fall," as seen in Romans 5:12 and 1 Corinthians 15:22; however, it says nothing about the possibility of plant or animal death prior to that. Setting aside the tautology that humans cannot die before being created, some creationist fundamentalists regard this as a profound New Testament revelation absent from Genesis, inferring that no death whatsoever occurred before the Fall. This interpretation often serves as a psychological counterbalance: death is unpleasant and unexpected in a supposedly perfect, evil-free world.

Creationists need to believe absurdities to cope with believing absurdities.

I'm not concerned about people clinging to absurd delusions for comfort, but what does concern me is the fact, confirmed by recent history, that those capable of believing absurdities can be persuaded to commit atrocities, often underpinned by the very book from which their delusions derive.

In a recent blog post, I mentioned the absurdity of believing that the food consumed by people or animals somehow remained alive through and after digestion. Additionally, the fossil record unequivocally demonstrates that plants and animals died tens to hundreds of millions of years before creationists' "creation week".

Now, paleontologists from the University of Leicester, led by Robert S. H. Smyth, have shed new light on why two juvenile pterosaurs in the 150-million-year-old Solnhofen Limestone of southern Germany died and were preserved in such extraordinary detail. These Solnhofen deposits are known for exquisitely preserved fossils, especially juveniles, but few intact adult remains.

A forensic-style examination revealed broken wing bones on the hatchlings - somewhat ironically nicknamed “Lucky” and “Lucky II” - consistent with storm-induced injuries, possibly from being hurled by powerful winds. These fractures likely prevented flight, causing them to crash into a lagoon, drown, and be rapidly buried by sediment washed in by the same storm—thus preserving them in remarkable fidelity.

These findings explain why juvenile pterosaurs are disproportionately represented in the Solnhofen fossil assemblage: young, relatively flight-inexperienced individuals suffered catastrophic outcomes during storms, while adults—better flyers—were less likely to meet the same fate, and their remains were more likely scavenged or fragmented before preservation.

Refuting Creationism - Why Plant-Mimicking Insects Make a Fool of ID Creationists

Scientists Discover 165-Ma Jurassic Orthopterans with Leaf Mimicry, First for Co-preserved Insect-Plant Fossils----Chinese Academy of Sciences

When we think of leaf mimicry, we usually picture modern insects like stick insects or katydids blending seamlessly into their surroundings. But new fossil discoveries show that this evolutionary trick is far older than we might imagine. In fact, insects were already disguising themselves as leaves 165 million years ago, during the Jurassic, long before flowering plants even appeared.

Scientists at the Chinese Academy of Sciences have uncovered an astonishing fossil example of close mimicry between three species of orthopteran insects—a group that includes grasshoppers, crickets, and katydids — and the leaves of an extinct cycad-like seed-bearing plant, almost certainly the very plant on which they lived. These fossils come from the 165-million-year-old Daohugou Biota of Inner Mongolia, northeastern China.

Instances of defensive mimicry or camouflage are exactly what one would expect from evolution by natural selection. In fact, it would be more surprising if potential prey species hadn’t evolved some form of defence. To an intelligent design advocate, however, such examples are awkward to explain—unless one imagines a forgetful designer who repeatedly undermines his own work. Why design predators that rely on a given prey species for food, and then deliberately design prey that are difficult for those predators to find? An arms race against oneself is hardly the hallmark of an intelligent mind.

And yet, arms races are precisely what we observe throughout the natural world — whether in competition for resources, the struggle for the fittest mate, parasite–host dynamics, or, as in this case, the evolutionary contest between predator and prey.
