名字的意思： “Baise lizard”1

吃：魚魚龍類三疊紀早期到三疊紀中期嚴格來說不是恐龍

Baisesaurus was an ancient marine reptile that swam in the oceans long before dinosaurs ruled the land. It was a strong swimmer with long, compact forelimb bones, and it likely ate fish and other sea creatures.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

Baisesaurus lived about 248 to 247 million years ago, during the Early Triassic period.2

Its name means 'Baise lizard' after the Baise region in China where its fossils were found.1

The only known fossil of Baisesaurus is a partial skeleton including ribs, vertebrae, and a limb bone.1

Baisesaurus was a basal ichthyosauromorph, meaning it was an early relative of later dolphin-like ichthyosaurs.1

Scientists think Baisesaurus was at least 3 meters (about 10 feet) long, similar in size to another early marine reptile called Utatsusaurus.1
