Simosaurus

Igama lithetha: “snouted lizard”1

Yayitya: InyamaIzirhubuluzi zaselwandleiTriassic ephakathi ukuya ku-iTriassic yamvaNgokwenene ayisiyo dayinaso

Simosaurus was a marine reptile that swam in warm, shallow seas during the Middle Triassic, about 240 to 230 million years ago. It had a blunt, flattened head and blunt teeth for crushing hard-shelled prey like clams and ammonites.1

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

izinto ezimnandi

Iinyani ezimnandi

Simosaurus had large openings behind its eyes called upper temporal fossae, which were bigger than its eye sockets.1

Its jaw joint was set far back, projecting beyond the main part of the skull, giving it a unique bite.1

Simosaurus had a flattened trunk that prevented side-to-side swimming, unlike most other nothosaurs.1

It swam using powerful downstrokes of its forelimbs, but its upstroke was weak, making it a moderately strong swimmer.1

The first Simosaurus fossils were found in Lunéville, France, and described by German paleontologist Hermann von Meyer in 1842.1

Simosaurus is known from the Muschelkalk deposits in Germany, where it appears in layers marked by the ammonite Ceratites nodosus.1

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

?How big was Simosaurus?

Simosaurus grew from 3 to 4 metres (9.8 to 13.1 ft) in length.1

?What did Simosaurus eat?

It ate hard-shelled organisms like ammonites and holostean fish, using its blunt teeth to crush them.1

?How did Simosaurus swim?

It swam with powerful downstrokes of its forelimbs, but its upstroke was weak, making it a moderately strong swimmer.1

Ukufunyanwa: German paleontologist Christian Erich Hermann von Meyer named Simosaurus in 1842 based on a skull from Lunéville, France. That original skull has since been lost.1
Kusaxoxwa ngayo: Scientists debate whether Simosaurus was a nothosaur, a pachypleurosaur, or a more primitive sauropterygian.1
