吃：魚海生爬蟲類三疊紀中期嚴格來說不是恐龍

Partanosaurus was a marine reptile that swam in the warm seas of the Middle Triassic, about 240 million years ago. It is known from just a few bones found in the Austrian Alps, and scientists are not sure exactly what it looked like.2 1

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

Partanosaurus was named in 1893 by Theodor Skuphos, based on a few bones from the back and chest of one animal.2 1

For many years, scientists thought Partanosaurus might be the same as another marine reptile called Simosaurus, but a 2019 study said it is too incomplete to be sure.1

Partanosaurus lived during the Ladinian age of the Middle Triassic, between about 241 and 237 million years ago.2

The only known fossils of Partanosaurus come from the Partnach Formation in the Austrian Alps.2

Partanosaurus is considered a nomen dubium, which means its name is doubtful because the fossils are too few and lack unique features.1

Partanosaurus belonged to a group of marine reptiles called sauropterygians, which includes long-necked plesiosaurs and shorter-necked nothosaurs.2

迷思： Partanosaurus was a dinosaur.

真相： Partanosaurus was a marine reptile called a sauropterygian, not a dinosaur. Dinosaurs lived on land.2
