吃：肉海生爬蟲類三疊紀晚期嚴格來說不是恐龍

Bobosaurus was a big marine reptile that lived in the sea during the Late Triassic, about 228 to 223 million years ago. It was a relative of plesiosaurs and had a long neck and strong flippers for swimming.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。

酷東西

趣味知識

Bobosaurus was named in 2006 by paleontologist Fabio M. Dalla Vecchia.1

The only known fossil is a partial skeleton that includes parts of the skull, neck, body, tail, and limbs.3

Bobosaurus had very high spines on its back vertebrae, similar to another marine reptile called Nothosaurus.3

Its ribs had a special hook-shaped process called an uncinate process, which is also seen in the placodont Paraplacodus.3

Bobosaurus lived during the Carnian age of the Late Triassic, about 237 to 233.6 million years ago.2

Scientists think Bobosaurus was a surface swimmer with a stiff body and large front flippers.3
