Vegasaurus

Naam beteken: “Vega lizard”1

Het geëet: VleisPlesiosourusseLaat KrytTegnies nie 'n dinosourus nie

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

Prettige feit: hierdie seereptiel het geswem terwyl dinosourusse op land geloop het. Almal noem hulle dino's, maar hulle was 'n ander tak van die reptiele.

Prettige feite

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

Vegasaurus is closely related to other plesiosaurs from the Weddell Sea region, like Aristonectes and Kaiwhekea.2 1
