Styxosaurus

Igama lithetha: “river of the dead lizard”1

Yayitya: InyamaIiplesiosauriiCretaceous yamvaNgokwenene ayisiyo dayinaso

Styxosaurus was a long-necked marine reptile that swam in the shallow seas that once covered North America. It was not a dinosaur, but a plesiosaur, and it used its sharp teeth to catch fish and squid.1 2

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

izinto ezimnandi

Iinyani ezimnandi

Styxosaurus had an extremely long neck, with over 60 vertebrae, making it one of the longest necks of any animal that ever lived.2

It lived in the Western Interior Seaway, a huge inland sea that split North America in two during the time of the dinosaurs.2

Some fossils of Styxosaurus were once thought to belong to a different animal called Hydralmosaurus, but scientists now think they are the same.2

Umfanekiso owenziwe yi-AI: Styxosaurus — Umfanekiso owenziwe yi-AI obonisa indlela Styxosaurus 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: Styxosaurus

?How big was Styxosaurus?

About 11.3 metres (37 ft) long and weighed around 3.1 metric tons (3.4 short tons). Its neck alone was about 5.25 metres (17.2 ft) long.4

?What did Styxosaurus eat?

It ate fish, squid, and belemnites. It grabbed slippery prey with its sharp, interlocking teeth and swallowed it whole.4

?When did Styxosaurus live?

It lived during the Late Cretaceous period, about 100 to 72 million years ago.4 5

?Did Styxosaurus have a long neck?

Yes, it had an extremely long neck with over 60 vertebrae, making it one of the longest necks of any animal.4 2

?Is Styxosaurus a dinosaur?

No, it is a plesiosaur, a marine reptile that lived in the sea, not a dinosaur.4

?Where was Styxosaurus found?

Fossils have been found in North America, mainly in Kansas, South Dakota, Nebraska, and Wyoming, in rocks that were once the bottom of a shallow sea.4 5

Kusaxoxwa ngayo: Scientists are still debating exactly how many species of Styxosaurus existed, and whether some fossils belong to this genus or to other elasmosaurids.2
