Paleontologists describe a new snake genus, Hibernophis breithaupti, from four nearly complete Oligocene specimens in Wyoming's White River Formation, setting a formal genus and suggesting the oldest evidence of communal hibernation in snakes, while illuminating early evolution and diversification of boa‑like snakes in North America.
Paleontologists in China discovered a new species of false saber-toothed cat, Taotienimravus songi, from the middle Oligocene era, which provides insights into early large carnivores and their ecological niches in Eurasia.
Scientists discovered four nearly complete snake fossils from 38 million years ago in Wyoming, leading to the identification of a new species, Hibernophis breithaupti. The fossils provide valuable insights into snake evolution, social behavior, and size development, suggesting that ancient boas were small and that communal hibernation behaviors existed millions of years ago. The exceptional preservation was due to volcanic ash covering the snakes' burrows, offering a rare glimpse into prehistoric reptile life.
Scientists have discovered a 25 million-year-old predatory dolphin with long, sharp teeth jutting straight out from its snout in a museum collection in New Zealand. The extinct dolphin, named Nihohae matakoi, lived during the late Oligocene epoch and likely ate soft-bodied animals like squids and octopuses. The researchers believe the dolphin may have used its teeth to thrash its prey to death, similar to the behavior of juvenile sawfish. The use of these strange jutting teeth should be investigated further to understand why they evolved and why teeth like this keep appearing in different groups of animals.
