Hispaniasaurus

Naam beteken: “lizard of Spain”1

Het geëet: VleisSeereptieleMiddel-TriasTegnies nie 'n dinosourus nie

Hispaniasaurus was a strange marine reptile that lived in the shallow seas of Spain about 240 million years ago. It had a long, rectangular skull with no openings on top, and its teeth were big and strong.1 2

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

Hispaniasaurus is known only from a partial skull, which is very small and rectangular in shape.2

The bones on top of its skull were highly vascularised, meaning they had lots of blood vessels. Scientists think this might have helped it feed in a special way.2

It lived during the Middle Triassic period, about 241 to 237 million years ago, in a shallow marine environment.3 2

The upper temporal openings on its skull might have been closed shut, which is unusual for reptiles.2

Hispaniasaurus belongs to a group called eosauropterygians, which includes nothosaurs and other ancient marine reptiles.3 2

Vir dino-kenners

Wetenskaplike naam: Hispaniasaurus
Benoem deur: Marquez-Aliaga et al. 20173
Groep: Seereptiele
Familie / klade: Eosauropterygia3
Klassifikasie: Sauropterygia3
Ouderdom van die rotse: 241 tot 237 miljoen jaar (Ladinian)3
Rotsformasies: Cañete3
Lande: Spanje3
Fossielrekords: 1 in The Paleobiology Database3
Ontdekking: Hispaniasaurus was named in 2017 by Ana Marquez-Aliaga and her team. The only fossil found so far is a partial skull from the Cañete Formation in Spain.1 3
Steeds omstrede: Scientists are not sure whether the upper temporal openings on its skull were completely closed or located further back, because the fossil is incomplete.2
