Vegasaurus was a long-necked marine reptile that swam in the cold seas near Antarctica about 72 million years ago. It was not a dinosaur, but a plesiosaur, and it used its four flippers to paddle through the water. This ancient creature is one of the few Late Cretaceous plesiosaurs from the Southern Hemisphere whose skeleton is well known.2 1
