吃：每樣都來一點海生爬蟲類三疊紀中期嚴格來說不是恐龍

Doliovertebra was a small marine reptile that swam in the seas during the Triassic Period, about 247 to 241 million years ago. It was a sauropterygian, a group of ocean-dwelling reptiles, but it was not a dinosaur.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

Doliovertebra lived in the Anisian age, which was about 247 to 241 million years ago, during the middle part of the Triassic Period.1

Its fossils were found in the Jena Formation in Germany, which was a marine environment at the time.1

The name Doliovertebra means 'barrel vertebra', which might refer to the shape of its backbone bones.2

Scientists think it was an actively moving animal that lived in the ocean, not on land.1

Doliovertebra is known from only one fossil site, making it a very rare find.1

迷思破解王

迷思： Doliovertebra was a dinosaur.

真相： Doliovertebra was a marine reptile called a sauropterygian, not a dinosaur. Dinosaurs lived on land and had different body features.2

發現: Doliovertebra was named by the scientist F. v. Huene in 1902. The first fossils were found at Freyburg an der Unstrut in Germany.2
仍有爭議: Scientists are not sure if Doliovertebra is a valid genus. Some researchers think it might be a nomen dubium, meaning the fossils are too incomplete to be certain about its identity.1
