A new species of fossil snake unearthed in Wyoming is rewriting our understanding of snake evolution. The discovery, based on four remarkably well-preserved specimens found curled together in a burrow, reveals a new species named Hibernophis breithaupti. This snake lived in North America 34 million years ago and sheds light on the origin and diversification of boas and pythons.
Palaeontologists are helping resolve the evolution and ecology of Odaraia, a taco-shaped marine animal that lived during the Cambrian period. Fossils reveal Odaraia had mandibles. Palaeontologists are finally able to place it as belonging to the mandibulates, ending its long enigmatic classification among the arthropods since it was first discovered in the Burgess Shale over 100 years ago and revealing more about early evolution and diversification.
The Cambrian fossil record indicates that most animal phyla had diversified and inhabited the Earth's oceans approximately 518 million years ago. But even though chordates—the group that includes vertebrates like humans—were part of this early animal diversification, they make up a relatively small portion of fossils from more than 50 Cambrian sites worldwide.
A team of paleontologists and natural science specialists from the U.K., the U.S. and France reports that ancient fossil evidence uncovered on Scotland's Isle of Skye suggests small mammals living millions of years ago may have had longer developmental periods and lifespans than those alive today.
