Simosaurus

Naam beteken: “snouted lizard”1

Het geëet: VleisSeereptieleMiddel-Trias tot Laat TriasTegnies nie 'n dinosourus nie

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

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

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

KI-prent van Simosaurus — 'n KI-prent van hoe Simosaurus dalk gelyk het, deur 'n rekenaar gemaak uit wat wetenskaplikes weet. Dit is 'n raaiskoot: die regte dier het dalk anders gelyk, en niemand weet wat sy regte kleure was nie.

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

Vir dino-kenners

Wetenskaplike naam: Simosaurus
Benoem deur: Meyer 18423
Groep: Seereptiele
Familie / klade: Simosauridae3
Klassifikasie: Nothosauria > Sauropterygia3
Ouderdom van die rotse: 247 tot 201 miljoen jaar ()3
Rotsformasies: Jilh, Erfurt, Gevanim3
Lande: Duitsland, Frankryk, Saoedi-Arabië, Israel, Italië3
Fossielrekords: 15 in The Paleobiology Database3
Ontdekking: 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
Steeds omstrede: Scientists debate whether Simosaurus was a nothosaur, a pachypleurosaur, or a more primitive sauropterygian.1
