吃：肉海生爬蟲類三疊紀中期嚴格來說不是恐龍

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

趣味小知識：這種海生爬蟲類在海裡游泳的時候，恐龍正在陸地上走路。大家都叫牠們恐龍，但牠們其實是爬蟲類的另一個分支。

酷東西

趣味知識

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

給恐龍專家

學名: Hispaniasaurus
命名者: Marquez-Aliaga et al. 20173
類群: 海生爬蟲類
科 / 演化支: Eosauropterygia3
分類: Sauropterygia3
岩石的年代: 241 到 237 百萬年 (Ladinian)3
岩層: Cañete3
國家: 西班牙3
化石紀錄: The Paleobiology Database 收錄 1 筆3
發現: 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
仍有爭議: 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
