2026 is shaping up to be yet another dreadful year for the creationist cult, as palaeontology, archaeology, geochronology, and genetics continue to uncover facts that do not merely show creationism to be a divinely inspired allegory or metaphor, but demonstrate that it is simply and unequivocally wrong at every level.

At times it seems like an unfair contest between myths invented by Bronze Age pastoralists—without the slightest benefit of scientific understanding—and the cumulative output of modern science. It is rather like a chess match between a pigeon and a powerful computer, in which the pigeon’s concept of chess is to knock the pieces over, then strut about on the board declaring victory. This tactic is known in creationist circles as “debate”, and everywhere else as “pigeon chess”.

As usual, the closing months of the year have brought yet more palaeontological evidence that creationism cannot accommodate. This latest find dates to around 37 million years before creationists believe Earth was magicked into existence, bears the unmistakable fingerprints of one of those supposedly “non-existent” transitional forms, and displays the familiar mosaic of archaic and modern features that are commonplace in the fossil record. It also fits precisely into the established timeline of reptilian evolution and was discovered in southern England, in deposits that align exactly with the known geological and climatological history of the region.

The fossil was discovered in 1981 at Hordle Cliff, England, and donated to the Natural History Museum in London, where it has now been identified as a new species. The identification was made by Professor Georgios L. Georgalis of the Institute of Systematics and Evolution of Animals at the Polish Academy of Sciences in Kraków, currently a visiting researcher at the Natural History Museum. His paper, co-authored with Dr Marc E. H. Jones, curator of fossil reptiles and amphibians, has recently been published open access in Comptes Rendus Palevol.

Hordle Cliff, Geology. Hordle Cliff is one of the most important and intensively studied fossil-bearing coastal exposures in southern England. Its significance lies in the exceptional sequence of Eocene marine sediments exposed by continual coastal erosion along the western Solent.



Geological setting

Hordle Cliff lies on the coast of Hampshire, west of Milford-on-Sea, forming part of the Hampshire Basin, a large sedimentary basin that accumulated marine and marginal-marine deposits during the early Cenozoic. The strata exposed here date mainly to the Late Eocene, approximately 41–34 million years ago, a time when southern England lay beneath a warm, shallow sea.

Stratigraphy

The cliff exposes a classic succession of Eocene formations, including:
  • Barton Group (upper Eocene)
    • Dominated by clays, silts, and fine sands
    • Deposited in shallow marine conditions
    • Exceptionally fossil-rich
  • Barton Clay Formation
    • The most famous unit at Hordle Cliff
    • Known for abundant molluscs, sharks’ teeth, rays, fish remains, turtles, crocodilians, birds, and reptiles (including snakes)
    • Indicates warm, subtropical seas with nearby coastal and estuarine environments

These sediments accumulated gradually, layer upon layer, in calm marine settings—exactly the opposite of the chaotic, high-energy deposition required by flood-geology models.



Depositional environment

During the Late Eocene, this region experienced:
  • **Warm greenhouse climates
  • High sea levels
  • Low-energy marine sedimentation

Fine-grained clays settled slowly out of suspension, allowing delicate fossils to be preserved intact. Many beds show bioturbation, shell beds, and orderly fossil assemblages—clear evidence of stable ecosystems persisting over long periods.



Fossil significance

Hordle Cliff is internationally important because it preserves:
  • Highly diverse faunas spanning multiple ecological niches
  • Mosaic evolutionary forms, including transitional reptiles
  • Fossils preserved in situ, not reworked or mixed from different ages

This makes the site particularly valuable for reconstructing Eocene ecosystems and tracing evolutionary change through time.



Structural and erosional features

The cliffs themselves are relatively soft and unstable:
  • Frequent slumping and landslips continually expose fresh material
  • Ongoing erosion has made Hordle Cliff productive for over two centuries
  • The geology is simple and undisturbed, with gently dipping strata—no folding, overturning, or tectonic chaos



Why this matters for creationist claims

The geology of Hordle Cliff presents multiple, independent problems for young-Earth creationism:
  • The sediments record millions of years of gradual deposition
  • Fossils are ordered, local, and ecological, not globally mixed
  • Climatic signals match global Eocene warming trends
  • The strata fit seamlessly into the wider regional and global geological record

There is no evidence whatsoever of rapid, catastrophic deposition, let alone a single global flood. Instead, Hordle Cliff is a textbook example of slow geological processes operating exactly as modern geology predicts.
The discovery and its broader significance were explained in a recent Natural History Museum news item by James Ashworth.
“Weird” new species of ancient fossil snake discovered in southern England
An extinct snake has slithered its way out of obscurity over four decades after its discovery.

The newly described species of reptile, Paradoxophidion richardoweni, is offering new clues in the search for the origin of ‘advanced’ snakes.

In 1981, the backbones of an ancient snake were uncovered at Hordle Cliff on England’s south coast. They’ve now been revealed as the remnants of a previously unknown species.

Research published in the journal Comptes Rendus Palevol has identified that the vertebrae belong to a new species named Paradoxophidion richardoweni. This animal would have lived around 37 million years ago, when England was home to a much wider range of snakes than it is now.

While little is known about this animal’s life, it could shed light on the early evolution of biggest group of modern snakes. This is because Paradoxophidion represents an early-branching member of the caenophidians, the group containing the vast majority of living snakes.

The new species is so early in the evolution of the caenophidians that it has a peculiar mix of characteristics now found in different snakes throughout this group. This mosaic of features is summed up in its genus name, with Paradoxophidion meaning ‘paradox snake’ in Greek.

Its species name, meanwhile, honours Sir Richard Owen. Not only did he name the first fossil snakes found at Hordle Cliff, but this scientist was also instrumental in establishing what’s now the Natural History Museum where the fossils are cared for, giving the name multiple layers of meaning.

Lead author Dr Georgios Georgalis, from the Institute of Systematics and Evolution of Animals of the Polish Academy of Sciences in Krakow, says that being able to describe a new species from our collections was ‘a dream come true’.

It was my childhood dream to be able to visit the Natural History Museum, let alone do research there, so, when I saw these very weird vertebrae in the collection and knew that they were something new, it was a fantastic feeling. It’s especially exciting to have described an early diverging caenophidian snake, as there’s not that much evidence about how they emerged. Paradoxophidion brings us closer to understanding how this happened.

What’s been discovered at Hordle Cliff?

Hordle Cliff, near Christchurch on England’s south coast, provides a window into a period of Earth’s history known as the Eocene that lasted from around 56 to 34 million years ago.

Dr Marc Jones, our curator of fossil reptiles and amphibians who co-authored the research, says that this epoch saw dramatic climatic changes around the world.

Around 37 million years ago, England was much warmer than it is now, though the Sun was very slightly dimmer, levels of atmospheric carbon dioxide were much higher. England was also slightly closer to the equator, meaning that it received more heat from the Sun year round.

Fossils were first uncovered at Hordle Cliff around 200 years ago. In the early 1800s Barbara Rawdon-Hastings, the fossil-hunting Marchioness of Hastings, collected the skulls of crocodile relatives from the site, one of which Richard Owen would later name after her.

Since then, a variety of fossil turtles, lizards and mammals have also been uncovered at Hordle Cliff. There are also abundant snake fossils, including some particularly important species.

The fossil snakes found at Hordle Cliff were some of the first to be recognised when Richard Owen studied them in the mid-nineteenth century. They include Paleryx, the first named constrictor snake in the fossil record. Smaller snakes from this site, however, haven’t been as well investigated. Paradoxophidion’s vertebrae are just a few millimetres long, so historically they’ve not had a lot of attention.

Dr Georgios Georgalis.

To get a better look at these fossils, Marc and Georgios took CT scans of the bones. In total, they identified 31 vertebrae from different parts of the spine of Paradoxophidion.

We used these CT scans to make three dimensional models of the fossils. These provide a digital record of the specimen which we’ve shared online so that they can be studied by anyone, not just people who can come to the museum and use our microscopes.

Dr Marc E.H. Jones.

The scans show that the fossils are all slightly different shapes and sizes, as the snake’s spine bones gradually taper from head to tail. However, they share some features that show they all belong to one species.

Georgios estimates that Paradoxophidion would have been less than a metre long, but other details about this animal’s life are hard to say. The lack of a skull makes it difficult to know what it ate, while the vertebrae don’t have any sign of being adapted for a specialised lifestyle, such as burrowing.

The backbones of Paradoxophidion are surprisingly similar to those of Acrochordus snakes.

A living link to the past?

Though the vertebrae don’t give much away about Paradoxophidion’s lifestyle, they are strikingly similar to a group of snakes known as the Acrochordids. These reptiles are known as elephant trunk snakes due to their unusually baggy skin.

Today, only a few species of these snakes can be found living in southeast Asia and northern Australia. But they’re among the earliest branches of the caenophidian family tree, with a fossil record extending back over 20 million years.

As Paradoxophidion is really similar to the acrochordids, it’s possible that this snake could be the oldest known member of this family. If it was, then it could mean that it was an aquatic species, as all Acrochordids are aquatic. On the other hand, it might belong to a completely different group of caenophidians. There’s just not enough evidence at the moment to prove how this snake might have lived, or which family it belongs to.

Dr Georgios Georgalis.

Finding out more about Paradoxophidion and the early evolution of the caenophidians means that more fossils will need to be studied. Georgios hopes to continue his work in our fossil reptile collections in the near future, where he believes more new species might be waiting.

I’m planning to study a variety of snake fossils in the collection, including those originally studied by Richard Owen. These include the remains of the giant aquatic snake Palaeophis, which were first found in England in the nineteenth century. There are also several bones with differing morphology that haven’t been investigated before that I’m interested in looking at. These might represent new taxa and offer additional clues about snake evolution.

Dr Georgios Georgalis.

Taken together, the geology of Hordle Cliff leaves no room for creationist evasions. The sediments accumulated slowly in warm, shallow Eocene seas, preserving stable marine ecosystems over millions of years. The fossils are local, ordered, and ecologically coherent, embedded within undisturbed strata that fit seamlessly into the wider geological history of southern England and the global Eocene record. None of this resembles the chaotic aftermath of a recent global catastrophe; all of it is exactly what conventional geology predicts.

The newly identified fossil from this site simply adds to the embarrassment. It is neither out of place nor out of time, but sits precisely where evolutionary theory says it should—both stratigraphically and anatomically—displaying the familiar mosaic of ancestral and derived features that creationists insist do not exist. Hordle Cliff has been yielding such transitional forms for over two centuries, and every one of them tells the same story.

For creationism, this presents a recurring and insoluble problem. Each new discovery must be dismissed, distorted, or ignored, not because it is anomalous, but because it fits too well. Hordle Cliff is not an exception to the rule; it is the rule itself—one more quietly devastating reminder that the natural world records its own history with remarkable consistency, and that history bears no resemblance whatsoever to a Bronze Age flood myth.

Unintelligent Design - When Snakes Borrow Genes from the Sea - It's Fatal To Creationism

New study unlocks mystery origin of iconic Aussie snakes | Newsroom | University of Adelaide

Intrigued by the information I unearthed while researching for my recent blog post about Australia's elapsid snakes and how skinks have evolved resistance to their venom, I discovered that these snakes have evolved from a common ancestor that once lived in the sea, and, while there, picked up a number of 'jumping genes' that are only found in marine animals as diverse as fish, sea squirts, sea urchins, bivalve molluscs and turtles.

The more we learn about genomes, the clearer it becomes that evolution is not a neat or predictable process—it is messy, opportunistic, and deeply influenced by historical contingency. A striking example of this comes from a recent genomic study that traced the origins of Australia’s iconic elapid snakes—not just through their DNA, but through the foreign DNA embedded within it. Researchers have identified at least 14 distinct horizontal gene transfer (HGT) events in these snakes, in which transposable elements—“jumping genes” — from unrelated marine organisms such as fish, tunicates, molluscs, and turtles have been incorporated into the snake genome.

This is compelling evidence that the ancestors of modern Australian elapids passed through a marine environment, acquiring genetic material from the organisms they encountered there. The transfers are not random. They show ecological specificity, temporally sequenced occurrence, and a nested pattern of inheritance — hallmarks of an evolutionary process rather than the actions of an intelligent designer.

For proponents of Intelligent Design creationism, this presents a serious interpretive problem. The idea that different species share features because of a “common designer” does not explain why Australian elapids should contain such a unique suite of genes from marine animals—genes absent in closely related snakes that remained on land. Nor does it account for the fact that many of these sequences serve no obvious function, are neutral or even mildly deleterious, and resemble the genetic detritus typical of unguided evolution.

ID advocates will likely claim this is just more evidence of “design reuse” or “genetic toolkits.” But such claims are not only ad hoc; they fail to explain the clear environmental and phylogenetic patterns observed in the data. The evolutionary explanation, by contrast, is both predictive and parsimonious: snakes dispersed through a marine environment, interacted with marine organisms, and as a result, their genomes bear the signature of that history.
In what follows, we will explore how this discovery not only sheds light on the evolutionary past of Australian elapids, but also exposes the weaknesses in ID’s core explanatory framework. The genome of a snake tells a story—and it's not the story of design.

A new paper published in the Zoological Journal of the Linnean Society should give creationists cause to wonder if the people who wrote their favourite creation myth knew what they were talking about. That's assuming they have enough courage and intellectual integrity to consider that evidence trumps superstition and not the other way round, which is a big ask for most creationists as it would also mean their mummy and daddy could have been wrong too.

The evidence the new paper reveals is that of a collection of fossilised snakes found in Oligocene rocks in western Wyoming are those of a new species from 38 million years before creationists believe the Universe was created out of nothing by magic, when snakes had legs and could talk, and didn't have to eat nothing but dust [sic].

Malevolent Design - Combatting The Highly Toxic, Tissue Destroying Spitting Cobra Venom

First effective treatment found for spitting cobra snakebite - Lancaster University

Snake venom is usually a potent cocktail of multiple different toxins, 'designed' to kill, mostly small vertebrate prey very quickly, so the snake can strike, then wait for the prey to become paralyzed or die before it can go very far.

The reason for this rich cocktail is an interesting piece of evolutionary biology that would embarrass any creationist with the courage to learn about it. It is the result of repeated arms races between the snake and its prey species. Not only that, but it involves new genetic information arising, by gene duplication and mutations - contrary to creationist dogma that such a thing is impossible.

As one prey species starts to evolve resistance there is selection pressure on the snake to change its venom to overcome the resistance or loose one source of food, but, there must be a balance between retaining one food species but loosing several others if the changed venom is less effective against them. Resistance usually arises when there is a change in receptor sites on cell surfaces, on which the venom acts so the active venom molecule doesn't bind to it.
