Two hundred and fifty million years ago, life on earth was in a tail-spin—climate change, volcanic eruptions, and rising sea levels contributed to a mass extinction that makes the death of the dinosaurs look like child’s play. Marine life got hit hardest—96% of all marine species went extinct. For a long time, scientists believed that the early marine reptiles that came about after the mass extinction evolved slowly, but the recent discovery of a strange new fossil brings that view into question.

In 2014, scientists discovered a bizarre fossil—a crocodile-sized sea-dwelling reptile that lived 242 million years ago in what today is southern China. Its head was poorly preserved, but it seemed to have a flamingo-like beak. But in a paper published today in Science Advances, paleontologists reveal what was really going on—that “beak” is actually part of a hammerhead-shaped jaw apparatus, which it used to feed on plants on the ocean floor. It’s the earliest known example of an herbivorous marine reptile. Read more about “Hammerhead” creature was world’s first plant-eating marine reptile
How is it that a Museum can have 1,200+ fossils of a particular species in its collection since the 1960's... and not even know what it is? For decades, it was thought the 'Tully monster' -- a bizarre animal that lived 307 million years ago -- was an invertebrate, like a kind of worm. But in March, Field Museum scientists helped finally crack the mystery of the monster, to reveal it's actually related to lamprey fish. BOOM. Read more about Tully monster mystery SOLVED!
