• Four well-preserved snake fossils were found intertwined in a single burrow, indicating possible social behavior.
• The new species, Hibernophis breithaupti, lived 34 million years ago and is related to modern boas and pythons.
• Articulated skeletons provided rare anatomical details, aiding in the identification of the species.
• The discovery suggests that northern and central North America played a key role in the evolution of burrowing boas.
• Researchers believe these snakes may have hibernated together to conserve heat, similar to modern garter snakes.
