Barracudasauroides

名字的意思： “barracuda-like”1

吃：肉魚龍類三疊紀中期嚴格來說不是恐龍

Barracudasauroides was a small, fast-swimming marine reptile that lived in the sea during the Middle Triassic, about 247 to 241 million years ago. It was not a dinosaur, but a type of ichthyosaur, with a long snout and sharp teeth for catching fish.5 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

Barracudasauroides had a skull less than 250 millimetres long, which is about the length of a pencil.2

It had 15 or fewer teeth in the front of its upper jaw, and those teeth were long, cone-shaped, and pointed.2

Its front teeth were weaker than its back teeth, which were stronger and more blunt.2

The bones in its skull behind the eye were arranged in a very old-fashioned way, more primitive than other mixosaurids.2

Its radius bone, in the front flipper, had two notches on the front edge, which is a special feature.2

It lived in the sea during the Anisian stage of the Middle Triassic, about 247 to 241 million years ago.5 1

發現: The first fossil, a partial skeleton, was found in the Guanling Formation in Guizhou, China. It was first named Mixosaurus panxianensis in 2006, but in 2010 Michael W. Maisch gave it its own genus, Barracudasauroides.1 2
仍有爭議: Scientists are still debating whether Barracudasauroides should be its own genus or just a species of Mixosaurus, because some think the differences are not big enough.2
