Caypullisaurus

名字的意思： “Caypulli's lizard”4

吃：肉魚龍類侏羅紀晚期到白堊紀早期嚴格來說不是恐龍

Caypullisaurus was a large, dolphin-like marine reptile that swam in the warm seas of what is now Argentina. It had a long, slender snout and huge eyes to hunt fish and squid in the dark ocean.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

Caypullisaurus had four main fingers in its front flipper, made of tightly packed, many-sided bones, plus extra fingers on the front and back edges.1

Its eyes were very large, like those of Ophthalmosaurus, helping it see in dim water.1

Adult Caypullisaurus had weak or missing teeth, so it probably sucked in soft prey like squid.1

The only known skeleton is the most complete ichthyosaur ever found from the Jurassic of South America.1

Caypullisaurus lived about 145 million years ago, during the Late Jurassic period.4

Its fossils were found in the Vaca Muerta formation, a famous rock layer in Argentina that also holds many other marine reptiles.4
