Manemergus

名字的意思： “snake neck”1

吃：肉蛇頸龍類白堊紀晚期嚴格來說不是恐龍

Manemergus was a plesiosaur, a marine reptile that swam in the warm seas of Morocco about 90 million years ago. It had a long, stiff neck and a narrow snout full of smooth, slender teeth for catching fish.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。

酷東西

趣味知識

Manemergus is known from a single skeleton of a juvenile, so scientists think it was a young animal when it died.2

Its neck was probably very stiff because the bones had strong ligaments connecting them, like tough rubber bands.2

Manemergus lived in the same place as another plesiosaur called Thililua, both found near the town of Goulmima in Morocco.1

It belonged to a group of plesiosaurs called polycotylids, which were fast swimmers with short necks and big heads.1 4

The name Manemergus means 'snake neck' in Latin, because its neck was long and snake-like.1
