Fossils shed light on 'bizarre' reptile
A crocodile-sized creature that lived 242 million years ago was the first known vegetarian marine reptile, according to new fossil evidence.
Two specimens unearthed in China reveal details of the animal's skull and how it fed.
Named Atopodentatus, scientists say its hammer-shaped skull helped it to feed on underwater plants.
