Vegasaurus

Igama lithetha: “Vega lizard”1

Yayitya: InyamaIiplesiosauriiCretaceous yamvaNgokwenene ayisiyo dayinaso

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

Inyani emnandi: esi sirhubuluzi saselwandle sasiqubha ngelixa iidayinaso zazihamba emhlabeni. Wonke umntu uzibiza ngokuba ziidayinaso, kodwa zazilisebe elahlukileyo lezirhubuluzi.

izinto ezimnandi

Iinyani ezimnandi

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

Umfanekiso owenziwe yi-AI: Vegasaurus — Umfanekiso owenziwe yi-AI obonisa indlela Vegasaurus esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

ubuzile

Eyona mibuzo ibuzwa kakhulu: Vegasaurus

?How big was Vegasaurus?

About 6.15 to 6.5 metres long and weighed around 839 kilograms.1

?What did Vegasaurus eat?

Scientists are not sure exactly what it ate, but it had gastroliths (stomach stones) that may have helped grind up food like fish or squid.1

?Where was Vegasaurus found?

Its only fossil was found on Vega Island, near the Antarctic Peninsula, in 1989.1

Ukufunyanwa: Vegasaurus was named in 2015 by José P. O'Gorman and colleagues. The only fossil was found in 1989 on Vega Island, Antarctica, and was collected during three Antarctic summer expeditions in 1993, 1999, and 2005.1
Kusaxoxwa ngayo: Scientists are still debating exactly how Vegasaurus is related to other plesiosaurs, especially the aristonectines.2 1
