吃：肉海生爬蟲類三疊紀晚期嚴格來說不是恐龍

Chelyoposuchus was a marine reptile that lived in the Late Triassic period, about 205 to 201 million years ago. It had a shell like a turtle and swam in ancient seas, but it was not a dinosaur.1 3

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

Chelyoposuchus is a type of placodont, a group of marine reptiles that often had turtle-like shells.1

Its name means 'turtle crocodile' because it looked a bit like both a turtle and a crocodile.1

The only known species is Chelyoposuchus crassisquamatus, which was named in 1939 by scientist O. Kuhn.1 3

Fossils of Chelyoposuchus were found in the Trossingen Formation in Germany, which is made of rocks from the Late Triassic.1

The first fossils were collected by Otto Jaekel between 1909 and 1913, but the animal was not named until 1939.1

Chelyoposuchus lived in a marine environment, meaning it swam in the ocean.2
