The discovery of a short-snouted, oceangoing reptile with a whip-like tail suggests that some marine reptiles evolved quickly (geologically speaking) after a mass extinction 250 million years ago, a new study finds. The finding turns an old theory on its head, showing that early marine reptiles didn't evolve slowly after the end-Permian extinction. The extinction wiped out about 96 percent of all marine species, largely due to climate change, volcanic eruptions and rising sea levels, the researchers said. The newfound specimen from China is an early ichthyosaur, a marine reptile that looks a bit like a dolphin. Its discovery suggests...
