Prepare to dive into a fascinating discovery that has left scientists intrigued! A 37-million-year-old snake ancestor has been unearthed, offering a glimpse into the ancient past and challenging our understanding of snake evolution. But here’s the twist: this find, made decades ago, has only recently revealed its secrets, leaving us with more questions than answers.
In a groundbreaking study, a team from the Natural History Museum has identified a new, extinct snake species from ancient backbones found on England’s south coast in 1981. Named Paradoxophidion richardoweni, this ancient creature lived millions of years ago, and its discovery is a game-changer for snake enthusiasts and scientists alike.
Dr. Georgios Georgalis, the lead author of the study, emphasizes the significance of this find, stating, “There’s not much evidence about how [advanced snakes] emerged. Paradoxophidion brings us closer to understanding this enigma.”
What makes Paradoxophidion unique is its early appearance in the evolutionary timeline of snakes. It exhibits a fascinating blend of traits, a mosaic of characteristics seen in various modern snake groups. This paradoxical nature inspired its name, translating to “paradox snake” in Greek.
The species is named in honor of Richard Owen, a pioneering scientist who named the first fossil snakes and played a pivotal role in establishing the Natural History Museum. The tiny backbones, just a few millimeters long, were discovered in 1981 but had remained relatively unnoticed until now.
Using advanced imaging techniques, the research team studied the remains, identifying 31 vertebrae from different sections of the snake’s spine. The scans even allowed for the creation of 3D models, shared online for global study. Through extensive analysis, the team confirmed that all the bones belonged to a single species, estimated to be less than a meter in length.
One of the most intriguing aspects is the potential aquatic lifestyle of Paradoxophidion. Due to the absence of a skull, its diet remains a mystery, and the vertebrae provide no clear signs of adaptation for specialized behaviors. However, the bones bear a striking resemblance to those of modern Acrochordids, or elephant trunk snakes, known for their loose skin. Since all living Acrochordids are aquatic, and Paradoxophidion shares many similarities with this family, it could be the oldest known member, suggesting an aquatic existence.
But here’s where it gets controversial: the evidence is not yet conclusive. More research is needed to determine its exact lifestyle and family classification.
The fossil site at Hordle Cliff offers a window into the Eocene epoch, a period of significant global climatic change. Around 37 million years ago, England enjoyed warmer conditions, maintained by higher atmospheric carbon dioxide levels and its more equatorial position.
Hordle Cliff has been a treasure trove for fossil hunters for over 200 years, with early discoveries dating back to the 1800s. The site has yielded a diverse range of fossils, from turtles and lizards to mammals and, of course, snakes.
The discovery of Paradoxophidion highlights the untapped potential of the museum’s collections, showcasing the wealth of knowledge yet to be uncovered.
The findings were published in the journal Comptes Rendis Palevol, and they leave us with an intriguing question: What other secrets lie hidden in the museum’s collections, waiting to be revealed?
