Odoiporosaurus

名字的意思： “traveler lizard”1

吃：魚海生爬蟲類三疊紀中期嚴格來說不是恐龍

Odoiporosaurus was a small marine reptile that swam in warm, shallow seas during the Middle Triassic, about 239 million years ago. It looked a bit like a modern sea turtle but with a long tail and four flipper-like legs. It lived in what is now northern Italy.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。

趣味知識

Odoiporosaurus is one of the oldest known pachypleurosaurs from the Besano Formation, older than its relative Serpianosaurus.3

Its name means 'traveler lizard' because scientists think its ancestors migrated from the eastern Paleotethys Ocean into the Germanic Basin.1 3

Odoiporosaurus is the sister group to the clade that includes Serpianosaurus and Neusticosaurus.1 3

The only known fossil of Odoiporosaurus was found in the Besano Formation, which is famous for preserving many marine reptiles from the Middle Triassic.1 3

Odoiporosaurus lived during the Anisian stage of the Middle Triassic, about 239 million years ago.1 2

This reptile was a pachypleurosaur, a group of small, long-necked marine reptiles that were not dinosaurs.1
