A 260-million-year-old fossil species Eunotosaurus africanus sheds new light on turtle evolution. Details of its skull provide the real clues.
Crocodiles roamed areas of Wyoming and Canada 50 million years ago, enjoying the temperate climates. But since these areas are so far from ocean warming effects, scientists wondered how they remained habitable for large aquatic reptiles.
Despite their long, long time on Earth, sharks and ray-finned fishes are losing in the competition of species proliferation. An evolutionary biologist has findings regarding land vs. water, and predictions for other biodiversity patterns.
Scientists have just discovered a new 9-foot-long crocodilian ancestor that was once one of North America's top predators, dominating the Earth before dinosaurs came on the scene, new research indicates.
About 13 million years ago in what is now northeastern Peru, ancient shell-crunching crocodiles ruled the Amazon, according to new research.
