Brachypterygius

名字的意思： “short wing or paddle”1

吃：肉魚龍類侏羅紀晚期到白堊紀早期嚴格來說不是恐龍

Brachypterygius was a fast-swimming marine reptile that lived in the Late Jurassic seas. It looked a bit like a dolphin but was a reptile, not a fish or a dinosaur. Its short, wide front flippers helped it steer through 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

Brachypterygius had a short, wide front flipper with up to six fingers, and some fingers had as many as 16 bones.1

Its skull was between 0.5 and 1.2 metres long, about the size of a big dog's head.1

The first fossil of Brachypterygius was just a single right front flipper, found in England.1

Brachypterygius lived during the Kimmeridgian and Tithonian ages, about 154 to 143 million years ago.3

It is closely related to other ichthyosaurs like Platypterygius and Caypullisaurus.1

Scientists once thought Brachypterygius was the same as another ichthyosaur called Grendelius, but now many think they are different.1
