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.

Refuting Creationism - Nosey Secrets of Triceratops Reveal Advanced Evolution - 100 Million Years Before 'Creation Week'

Why Triceratops has such a big nose | The University of Tokyo

Once upon a time, in that ancient world during the 99.975% of Earth’s history that elapsed before creationism’s small god supposedly conceived the idea of creating a small flat plane with a dome over it in the Middle East, there lived a dinosaur that had evolved a horned head and a wide protective frill to shield its vulnerable neck from the jaws of the large predators that ruled the land some 100 million years ago. Carrying those horns and that protective neck shield required a large head — and a large head is difficult to keep cool.

The solution, according to researcher Seishiro Tada of the University of Tokyo Museum, was a large nasal cavity containing turbinate bones to mix incoming air, together with a plentiful blood supply to dissipate excess heat. Tada and colleagues from various Japanese research institutions have recently published their findings in The Anatomical Record.

This is not a fairy story, but what palaeontology is revealing.

From an evolutionary perspective, this research shows that Triceratops was the product of a long evolutionary process in which predation drove the development of large defensive structures, which in turn created new physiological challenges — in this case, the risk of overheating. Those challenges then drove further evolutionary adaptations. In other words, the solution to one problem generated another problem to be solved, all as part of a predator–prey arms race. This dynamic makes no sense as the work of an intelligent designer, but it is precisely what evolutionary theory predicts.

Almost eight weeks into the New Year and not a single scientific paper has emerged in support of creationism—or its pseudo-scientific variant, Intelligent Design. Not even a speculative hint of the long-predicted collapse of ‘Darwinism’, nor any sign that Intelligent Design is making inroads into biomedical science. Instead, the steady flow of research continues to do precisely the opposite: quietly and methodically reinforcing evolutionary biology as the indispensable framework through which palaeontology, cell biology, virology and the rest of modern life sciences make coherent, testable sense of the evidence.

Today brings yet another example. An international team led by researchers from the Centre national de la recherche scientifique (CNRS), working at the Université de Rennes, has identified a new species of iguanodontian dinosaur that lived in what is now China around 125 million years ago. Their paper, recently published in Nature Ecology & Evolution, reports that this species was probably covered in hollow spikes, somewhat reminiscent of porcupine quills. The team have named the new species Haolong dongi in honour of Dong Zhiming, a pioneer of Chinese palaeontology.

Using X-ray scans and high-resolution histological sections, the researchers were able to identify preserved skin structures, revealing hollow cutaneous spikes over much of the animal’s body. Although herbivorous, this dinosaur lived in an environment where predation pressure from small carnivores would have been significant, and the spikes likely provided a degree of protection comparable to that of modern porcupines. The structures may also have played roles in thermoregulation and/or sensory perception.

Tiny new dinosaur Foskeia pelendonum reshapes the dinosaur f | Vrije Universiteit Brussel

Researchers from the Vrije Universiteit Brussel (VUB), working with colleagues in Spain and elsewhere in Europe, have just described a remarkable new species of dinosaur from the Early Cretaceous of northern Spain. Their findings are the subject of a read-only paper in Papers in Palaeontology.

The tiny herbivore, named Foskeia pelendonum, lived around 125 million years ago, yet it is already forcing palaeontologists to rethink part of the ornithopod family tree. The discovery provides another striking example of how the fossil record continues to grow in detail, resolution, and explanatory power.

This will come as an unwelcome development for creationists, who still cling to the claim that evolution is “just speculation” and that the fossil record contains no meaningful evidence of transitional relationships or evolutionary diversification. On the contrary, finds like Foskeia show exactly what evolutionary science predicts: new lineages appearing in the right strata, in the right environments, with a mixture of ancestral and derived traits that help clarify how later forms evolved.

Creationists will, of course, respond in the usual way. Some will insist that this dinosaur is “just another dinosaur”, as though classification and evolutionary relationships are irrelevant. Others will retreat to the vacuous assertion that it represents merely “variation within a kind”, without ever defining what a “kind” is or explaining why such variation produces a nested hierarchy that maps so precisely onto geological time. And as always, the more committed will simply dismiss the evidence altogether, because no amount of fossil discovery can compete with a belief system that must remain true regardless of what the rocks contain.

Yet the significance of Foskeia pelendonum lies precisely in the details. This was not simply a juvenile form of a larger dinosaur, but a genuinely small-bodied species, confirmed by bone histology to have reached adulthood. Even more intriguingly, it possessed unexpectedly specialised skull and dental features, showing that evolutionary change does not always follow the simplistic “bigger and more advanced” caricature imagined by creationists, but often proceeds through ecological experimentation, miniaturisation, and adaptation to local conditions.

Far from undermining evolutionary theory, discoveries like this strengthen it. They refine the dinosaur family tree, help fill long-recognised gaps in the ornithopod record, and demonstrate once again that the history of life is written not in Bronze Age mythology but in the sedimentary archive of deep time — an archive that continues to contradict creationism with every new fossil unearthed.

Creationism Refuted - A Rich Collection of Dinosaur Fossils from 72 Million Years Before 'Creation Week'

The ancient environment and its fauna.

Reconstruction by Tibor Pecsics

Paleontoligists have discovered an exceptionally rich dinosaur site in Transylvania.

Normally, creationists seize on any concentration of animal fossils that can be attributed to flooding as supposed “evidence” for their favourite Bronze Age myth of a global genocide. On that basis, they should be delighted by recent news from Romania describing a rich deposit of dinosaur fossils that appears to have accumulated as a result of flooding in the Hațeg Basin.

There is, however, a serious snag. These fossils occur in deposits dated to around 72 million years ago — tens of millions of years before creationists believe the Earth even existed — and the evidence points clearly to repeated local flooding events, not a single global catastrophe.

The discovery of the fossil site is reported in the journal PLOS ONE by the Valiora Dinosaur Research Group, a collaboration of Hungarian and Romanian palaeontologists co-led by Gábor Botfalvai and Zoltán Csiki-Sava of the Institute of Geography and Earth Sciences, Department of Palaeontology, ELTE Eötvös Loránd University, Budapest, Hungary.

This, the second paper, published in 2022 that utterly refutes creationism on several different levels, reports evidence that particularly undermines their claim that an omnibenevolent god created a world fine-tuned for life.

This belief arises from a deeply ignorant, rose-tinted view of the world — one that conveniently ignores history and habitually attributes anything bad to something else: sin, free will, or other theological constructs that, by their own narrative, could only have applied after some supposed “fall”.

In reality, even a superficial understanding of Earth’s history — 99.9975 % of which took place before creationism’s legendary “Creation Week” — reveals that the planet is anything but fine-tuned for life. Life on Earth has repeatedly been subjected to mass extinctions triggered by geological and cosmological catastrophes that wreaked havoc on the environment, often at a pace too rapid for most species to adapt.

One of the most famous of these events was the meteor impact in what is now the Yucatán Peninsula, 66 million years ago. This strike plunged the planet into a “nuclear winter” as atmospheric dust blotted out the Sun. Within weeks, almost all large species were exterminated, leaving only the avian dinosaurs — likely shielded by insulating feathers — and early mammals, protected by their insulating fur.

But as this recent paper shows, the dinosaurs were thriving in a healthy, biodiverse environment in which they were the dominant species right up until the moment the meteor struck. Had they shared the creationists’ mindset, they might well have concluded that Earth was “fine-tuned” for them too.

The evidence for this comes from an international team of palaeontologists and ecologists, including researchers from University of Oulu (Finland), Universidade de Vigo (Spain), University of Washington (Seattle, USA), University College London (UK), New Mexico Museum of Natural History and Science (USA), and University of Edinburgh (UK).

New Jurassic ichthyosaur species discovered in Mistelgau

It's shaping up to be another bad week for creationism, with the evidence for evolution on an old Earth continuing to accumulate, and evidence against any intelligence being involved in its evolution growing unabated. There is even a paper describing how and when Earth was really formed, and the contrast between that reality and the Bible’s version could hardly be greater.

This article looks at just one of these developments (more will follow). From the perspective of evolutionary biology, it is not especially remarkable—simply the description of a new species of extinct ichthyosaur, Eurhinosaurus mistelgauensis, from the Lower Jurassic (around 200 million years ago).

But for creationism, it serves as yet another stark reminder of how wrong the biblical creation story and timeline are. To put it bluntly, this fossil would not exist if the Bible’s story were true. It doesn’t take a genius to see how the fact of its existence bears on debates about the truth or falsity of Genesis—though creationists appear to struggle with this basic deductive logic.

September: Newtonsaurus identification | News and features | University of Bristol

A newly-identified dinosaur from the Late Triassic of Wales has turned out to be hiding in plain sight. The fossil, discovered in 1899 and displayed for years in the National Museum of Wales, has only now been correctly recognised thanks to modern imaging technology unavailable to earlier researchers.

Originally described by Edwin Tully Newton in 1899 as Zanclodon cambrensis, the specimen has now been reclassified by a team of palaeontologists led by Owain Evans of Bristol University. Since the name Zanclodon is no longer used for early reptiles, the team have given it a new name: Newtonsaurus.

As always, discoveries like this present a problem for creationists. Fossils of species that lived tens or even hundreds of millions of years ago sit uneasily with their narrative that all life was magically created just a few thousand years ago. To preserve that story, they are forced into feats of mental gymnastics — whether by bearing false witness against scientists, rejecting well-established dating techniques, or simply dismissing the evidence outright as “wrong.”

The rocks, however, are not so easily ignored. Unlike ancient manuscripts, said to have been dictated by a god to prophets and accepted only on faith, the fossil record is physical, testable, and open to constant re-examination. Evidence can be checked, rechecked, and reassessed as methods improve — something faith alone cannot provide.

‘Teen’ Pachycephalosaur Butts Into Fossil Record | NC State News

Here we have another of those regular discoveries which, according to the press, supposedly means history will need to be “re-written” — something creationists, always looking for a stick to beat science with, will assume means the whole of history, because science has got everything wrong yet again. Unlike their religion, of course, which — so they claim — has never got anything wrong and is therefore eternally true, including the parts about a six-day creation 6,000–10,000 years ago, a global flood which left no evidence, and a universe consisting of a small, flat planet with a dome over it.

In reality, this is merely journalistic hyperbole designed to draw the reader in — or, in the case of creationists, to be seized upon as ‘scientific’ evidence that science is fatally flawed.

The “re-written” part of history is simply the bit about which we previously had no information. The process is not one of tearing up the past but of filling a gap in our knowledge and thereby arriving at an account closer to reality. In this case, “re-writing the history books” will mean telling a more complete history of a group of dinosaurs. The discovery in question is a 108-million-year-old adolescent pachycephalosaur fossil found in the Gobi Desert, Central Asia. Being both the oldest (by about 15 million years) and the most complete skeleton of this group of dinosaurs yet discovered, it provides crucial information about their origins.

Newly dated 85-million-year-old dino eggs could improve understanding of Cretaceous climate

The dating of a clutch of fossil dinosaur eggs will leave creationists scrambling for excuses to dismiss the evidence and cling to the childish notion that Earth is only 6,000–10,000 years old, created ex nihilo by magic, with all extant and extinct species brought into existence without ancestors just a few days later. In other words, this discovery is yet another small addition to the mountain of evidence showing that the biblical creation story was the work of ignorant Bronze Age people trying to make sense of the world around them, not the word of an omniscient creator god who would have known better.

An added problem for creationists is that the research team used a new method of dating the eggs based on measuring when the eggshell itself formed, rather than relying solely on dating the rock in which the eggs were embedded. The difficulty with the latter approach is that, while it gives the age of the surrounding rock, the mineral grains in that rock may predate the eggs and could have been transported there by water or wind.

The new technique is conceptually similar to the uranium–lead (U–Pb) method used to date zircon crystals in volcanic tuff. Tiny amounts of uranium, which readily substitute into the crystal lattice, are incorporated when the zircon forms, but lead is excluded. Over time, uranium isotopes decay into stable isotopes of lead. Thus, any lead present within a zircon crystal must have come from radioactive decay, and by measuring the ratio of uranium to lead isotopes, scientists can calculate the crystal’s age with high precision.

A very similar process occurs in the carbonate of dinosaur eggshells: uranium is incorporated during formation, but lead is excluded. Measuring uranium–lead isotope ratios in the shell carbonate therefore provides a direct and highly accurate age for the eggs themselves, leaving little room for error.

What Dinosaur Teeth Reveal About Life 150 Million Years Ago - Information for Media and Journalists | Freie Universität Berlin

An international team of researchers, led by Dr Daniela E. Winkler (postdoctoral researcher at Kiel University), Dr Emanuel Tschopp (visiting scientist at the Leibniz Institute for the Analysis of Biodiversity Change and research associate at Freie Universität Berlin), and André Saleiro (PhD student at NOVA University Lisbon), has shed new light on the diet and movements of the 150-million-year-old long-necked dinosaur, Giraffatitan.

By using high-resolution microscopy to examine patterns of microscopic wear on fossilised teeth, the team could reconstruct not only what Giraffatitan ate, but also how it foraged and where it roamed. The results show that these enormous sauropods fed on a wide range of vegetation, from soft leaves to tougher plant material, indicating a flexible feeding strategy. The wear patterns also suggest that the animals migrated across different habitats, rather than remaining in one area, allowing them to exploit seasonal changes in plant availability. This paints a picture of a highly adaptable browser, capable of sustaining its gigantic size by ranging widely across the Jurassic landscape.

In many ways, their lifestyle resembles that of today’s elephants or giraffes, which travel long distances to reach food and switch between different types of vegetation depending on what is available. Like elephants stripping branches or giraffes plucking leaves from the tops of trees, Giraffatitan used its immense neck to access food that other animals could not, helping to reduce competition and maintain the balance of its ecosystem.

They also represent an interesting example of convergent evolution where two unrelated species, in this case a dinosaur and giraffes, converge on the same solution to the same environmental problem - how to reach the leaves at the top of tall trees, so avoiding competition with other browsing animals - long necks and long front legs.

As ever, such discoveries are impossible to reconcile with creationist notions of a young Earth, supposedly only 6,000–10,000 years old. Yet this is merely one more example of the widening gulf between the reality uncovered by science and the superstitions preserved in ancient texts. These texts, after all, were written by Bronze Age pastoralists who imagined the universe as a flat disc beneath a dome, bounded by the few square miles they could walk in a couple of days across the Canaanite hills.

“Bizarre” armoured dinosaur, Spicomellus afer, had spikes sticking out from its neck, fossils show - University of Birmingham

A newly-identified bizarre dinosaur fossil from Morocco has presented creationists with yet another thorny problem to ignore.

It is that of an ankylosaur from early in the evolutionary history of that group. Not only is its great age a problem for those who believe Earth was magicked into existence by a god with all living things fully formed and an environment perfectly tuned for life (i.e. human life — supposedly the god’s favourite), but at 165 million years old it comes from the vast span of Earth’s pre-“Creation Week” history — that 99.9975% of the planet’s history which creationists pretend never happened. This is, in fact, the oldest ankylosaur yet discovered.

Unlike later ankylosaurs, however, this one had long spikes firmly attached to its bones. These appear to have been lost as the group evolved, showing relatively rapid change. That in itself runs counter to the creationist dogma that evolution cannot proceed by loss of genetic information and must always involve increasing complexity for it to be “real” evolution. This claim, like so many creationist assertions, ignores abundant evidence — such as the reduction in genome size and anatomical complexity in many endoparasites.

Now they have yet another example to ignore while busily constructing their infantile strawman versions of evolution to attack.

The discovery by palaeontologists co-led by Professor Susannah Maidment of Natural History Museum, London, and the University of Birmingham, has just been reported in Nature and is explained in a news item from the University of Birmingham and an accompanying YouTube video:

Creationism Crushed - By Big Biting Dinosaurs

Dinosaur bite illustrations.

Rowe and Rayfield, Current Biology (2025)

Gigantic, meat-eating dinosaurs didn’t all have strong bites | EurekAlert!

Creationists will likely dismiss the recent paper in Current Biology because, as is common in creationist psychology, any scientific evidence contradicting their fundamental beliefs is either ignored, misrepresented, or actively denied—particularly if it suggests their views should be reconsidered.

The study by Andre J. Rowe and Emily J. Rayfield of the University of Bristol (UK) demonstrates that, during the long stretch of Earth’s history predating creationist timelines, giant carnivorous dinosaurs evolved markedly different jaw mechanics to tackle prey—leading to distinct ecological roles. For example, crushers such as Tyrannosaurus rex developed jaws optimised for forceful crushing, akin to crocodilians, whereas slashers - other large theropods such as allosaurids or spinosaurs - developed weaker jaws tailored to ripping and slashing flesh, like modern Komodo dragons [1.1].

This divergence in feeding mechanics underscores a fundamental principle in evolutionary biology: adaptive radiation and allopatric speciation — whereby offspring inheriting intermediate jaw characteristics (neither fully adapted for crushing nor ripping) would likely be at a disadvantage, reducing their reproductive success. Over time, this selective pressure fosters reproductive barriers and drives lineages apart.

Creationism Refuted - How The Survivors of a Mass Extinction Evolved Into Dinosaurs

Contrary to the child-like naivety and carefully cultivated ignorance of creationists, Earth is not — and never has been — a paradise perfectly designed for life, let alone tailor-made for humans. In reality, the vast majority of Earth's history — around 99.9975% of it — took place long before creationists believe the planet even existed, during which time the environment has frequently become so hostile that mass extinctions wiped out the majority of living species. Life as we know it today descends from the lucky few that managed to survive and adapt to radically altered conditions.

One of the most devastating of these extinction events was the end-Permian climate catastrophe, during which one group of reptiles — the archosauromorphs — managed to endure. From this resilient lineage emerged the dinosaurs, who would go on to dominate the planet until they too were annihilated by a cataclysmic meteor impact 66 million years ago.

While palaeontologists have long known about the survival and evolutionary significance of archosauromorphs, a lingering mystery remained: how did they manage to disperse across vast "dead zones" of the tropics, where temperatures were thought to be lethally high? A new study by researchers from the University of Birmingham and the University of Bristol has now shed light on this question. Their findings have been published, open access, in Nature Ecology & Evolution.

One of the major challenges for creationism is how to ignore the overwhelming volume of evidence that contradicts it—especially from the vast span of Earth’s pre-'Creation Week' history, during which 99.9975% of geological time unfolded. Even allowing for their standard claim that scientists fake their dates and Earth is really only a few thousand years old, there is a vast amount of history to compress into so short a timeline.

During that immense period, something remarkable was happening: a distant ancestor of Tyrannosaurus rex, destined to become one of the most formidable land predators the planet has ever seen, was making its way across a land bridge from Asia into North America.

That’s the conclusion of a new study led by researchers at University College London (UCL), recently published in Royal Society Open Science. The team found that this transcontinental migration—via the Beringian land bridge over 70 million years ago—marked a key moment in the evolution of tyrannosaurids. They also noted a rapid increase in body size that appears to have coincided with a global cooling event following a climatic peak around 92 million years ago. The study was a collaboration between scientists from UCL and the universities of Oxford, Pittsburgh, Aberdeen, Arizona, Anglia Ruskin, Oklahoma, and Wyoming.

To normal people, the discovery of feather-eating beetles and feather fragments in 105-million-year-old amber, 30 million years before there were birds might be a clue that something had feathers before bird had them, suggesting that birds might have evolved from whatever that was.

Not so, creationists, however. Creationists conclude that any evidence that doesn't agree with them must be wrong because their evidence-free dogma is sacred and therefore uninfluenced by real-world evidence.

So, the following is just something else for creationists to ignore while they pretend to know better than the experts who have, unlike creationists, actually studied the subject.

It is news that a study, co-led between the Geological and Mining Institute of Spain of the Spanish National Research Council (CN IGME-CSIC) and Oxford University Museum of Natural History (OUMNH) has shown that beetles fed on the feathers of dinosaurs about 105 million years ago. This is based on an analysis of spectacular fossil amber fragments, from the locality of San Just in north-eastern Spain, revealed moults of tiny beetle larvae tightly surrounded by portions of downy feathers.

The feathers belonged to an unknown theropod dinosaur that lived around 105 million years ago, during the Early Cretaceous. This means that the feathers could not have come from a ‘modern bird’ species, since current evidence indicates that this group appeared about 30 million years later in the fossil record, during the Late Cretaceous.

If there is anything guaranteed to have creationists metaphorically, if not actually, screwing up their eyes, putting their hands over their ears and jumping up and down shouting "'Tisn't! 'Tisn't!

This event reminds them not only that Earth is very much older that their cult requires them to believe but also that Earth is not the 'finely-tuned' haven for life that their belief in a perfect creator requires them to believe. Instead, Earth is very old and subject to unpredictable catastrophes, not the least of which are cosmological events such as meteor strikes and the consequential mass extinctions.

Research reveals the most complete dinosaur discovered in the UK in a Century | University of Portsmouth

The fossil remains of a dinosaur, discovered in the cliffs of Compton Bay, Isle of Wight, England, have been shown to be a species new to science. The fossils were discovered in 2013 by the late fossil collector Nick Chase, who sadly died of cancer before his finds could be fully analysed. Nick Chase had a record of fossil discovery, including the most complete Iguanodon skull ever found, yet never had a new species named after him

That has now been rectified by retired GP and PhD student at the School of the Environment, Geography and Geosciences, University of Portsmouth, UK, Jeremy Lockwood, who helped with the dinosaur's excavation and has spent years analysing it to determine that it is a new species which he has named Comptonatus chasei. It has proven to be the most intact dinosaur ever discovered in Britain.
