Carentonosaurus

名字的意思： “lizard from the Charente region of France”3 1

吃：肉滄龍類白堊紀晚期嚴格來說不是恐龍

Carentonosaurus was a marine lizard that swam in warm, shallow seas during the time of the dinosaurs. It had a strange, heavy backbone that made it extra dense, like a living anchor in the water.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

Carentonosaurus had very thick, heavy bones in its back, a condition called pachyostosis, which helped it stay underwater without floating up.1

Its neck bones were not thickened, only the back bones were pachyostotic, which is unusual among marine lizards.1

This lizard lived about 100 to 94 million years ago, during the Cenomanian stage of the Cretaceous Period.3

Carentonosaurus fossils have been found in France, Portugal, and Spain, showing it lived in the warm Tethys Sea.2

It is part of a group called aigialosaurs, which are close relatives of the giant mosasaurs.3

The first fossils were discovered in western France, in rocks that were once a shallow, warm sea near a coast.1
