Vegasaurus
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.21

ເລື່ອງໜ້າຮູ້ມ່ວນໆ
Vegasaurus had 54 neck vertebrae, which is more than most other plesiosaurs.1
The only known fossil of Vegasaurus was found in 1989 by a team of scientists on Vega Island, Antarctica.1
This plesiosaur had gastroliths, or stomach stones, which may have helped it digest food or control its buoyancy.1
Vegasaurus is named after Vega Island, where it was discovered, and the Greek word for lizard, 'sauros'.1
Its humerus (upper arm bone) had a forward-facing knee and a backward projection with an extra joint surface, a feature only shared with a few other plesiosaurs.1
