Scientists find 245 million-year-old burrows of land vertebrates in Antarctica

... about 245 million years ago. The fossils were created when fine sand from an overflowing river poured into the animals' burrows and hardened into casts of the open spaces.

The Eocene age calculated by the Science researchers casts some doubt on another mystery involving seep animals: what is their relationship to whale falls? Whale falls, the slowly decaying remains of large ...

Did feathered dinosaurs exist?

... majority of evidence supports a 2-3-4 digit identity for bird wings. The bird hand "appears different from that in theropod dinosaurs," they say, and casts doubt upon the theropod derivation hypothesis.
