吃：魚海生爬蟲類三疊紀中期嚴格來說不是恐龍

Sanchiaosaurus was a marine reptile that swam in the warm seas of what is now China about 245 million years ago. It was a nothosaur, a type of long-bodied reptile that paddled through the water with its flippers. Scientists only know it from one partial skeleton found near Guiyang City.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

Sanchiaosaurus is known from just one skeleton, which is preserved with its belly facing up, so scientists see it from below.1

The name Sanchiaosaurus comes from Sanchiao, the place where it was found, and the Greek word 'sauros' meaning lizard.1

This reptile lived during the Anisian stage of the Middle Triassic, about 245 million years ago.1

The only known fossil of Sanchiaosaurus is kept at the Institute of Vertebrate Paleontology and Paleoanthropology in China.1

Sanchiaosaurus was a nothosaur, a group of marine reptiles that were not dinosaurs but lived in the sea.1

The skeleton includes the skull, lower jaw, one loose tooth, and parts of the body after the skull.1
