New Species of Extinct Snake Found in Wyoming Fossil: Unraveling Ancient Secrets

The Fossil Find

Name and Origin: The fossilized snake, officially named Hibernophis breithaupti, was unearthed in Wyoming. It provides a rare glimpse into the distant past when these reptiles roamed North America.

Social Lives Revealed: Four remarkably well-preserved specimens of Hibernophis breithaupti were found huddled together. This unique clustering hints at social behavior, a rarity among reptiles. These ancient snakes were fossilized within a structure called a hibernaculum—a cozy space where animals seek warmth during winter months.

Anatomical Features: The articulated skeletons of Hibernophis breithaupti are a scientific treasure. Unlike most fossil snakes, these specimens were found intact, with bones arranged in their original order. This unusual preservation sheds light on the snake’s anatomy and evolutionary history.

Insights into Snake Evolution

Boas and Pythons: Researchers believe that Hibernophis breithaupti may be an early member of Booidea, a group that includes modern boas and pythons. While modern boas are widespread in the Americas, their early evolution remains enigmatic. This discovery provides crucial information about their origins.

Burrowing Boas: Traditionally, the evolution of small burrowing boas has sparked debate. Hibernophis breithaupti suggests that northern and central parts of North America played a pivotal role in their development. These fossils offer a window into the ancient ecosystems where these snakes thrived.

Hibernation in Groups

Ancient Behavior: The curled-together fossils hint at an intriguing behavior—hibernation in groups. Modern garter snakes are known to gather by the thousands in dens and burrows for warmth during colder months. The discovery of Hibernophis breithaupti provides the oldest potential evidence of this social behavior, dating back 34 million years.

Heat Conservation: Michael Caldwell, a paleontologist from the University of Alberta, explains that garter snakes hibernate together to conserve heat. The ball of hibernating animals creates an effective insulation mechanism. Witnessing this behavior in ancient snakes adds a fascinating layer to our understanding of their lives.

Conclusion

Hibernophis breithaupti invites us to explore the mysteries of prehistoric reptiles. As we unravel its secrets, we gain valuable insights into snake evolution, social dynamics, and the ancient landscapes they inhabited. This remarkable discovery reminds us that the past holds hidden wonders waiting to be revealed.
