Suevoleviathan

名字的意思： “Swabian Leviathan”1

吃：肉魚龍類侏羅紀早期嚴格來說不是恐龍

Suevoleviathan was a giant, fish-like marine reptile that swam in the warm Jurassic seas. It was not a dinosaur, but a kind of ichthyosaur with a long tail and big front flippers.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

Suevoleviathan had unusually large front flippers compared to other ichthyosaurs, which it used for slow swimming.1

Its tail was very long and flexible, helping it steer at high speeds.1

The front flipper had three main fingers and one extra finger, with the third finger splitting into three rays.1

Scientists think Suevoleviathan gave birth to live young, like other ichthyosaurs.2

Its fossils were found in the Posidonia Shale, a rock layer famous for well-preserved Jurassic sea creatures.1 3

Suevoleviathan lived about 183 to 182 million years ago, during the Early Jurassic period.1
