吃：肉魚龍類侏羅紀晚期到白堊紀早期嚴格來說不是恐龍

Arthropterygius was a large, fish-shaped marine reptile that swam in the oceans during the late Jurassic period. It had a long snout and strong flippers, and it was a fast hunter of fish and squid.1 3

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。

趣味知識

Arthropterygius had a special opening for the internal carotid artery on the back of its braincase, a feature unique among ichthyosaurs.2

Fossils of Arthropterygius have been found in both the Northern and Southern Hemispheres, showing it lived in warm and cold seas.1 2

One specimen from Svalbard, Norway, was about 3.8 to 4.3 metres (12 to 14 feet) long and was probably an adult.1

The name Arthropterygius means 'wing fin', referring to the shape of its flippers.1

Arthropterygius lived in shallow seas with methane seeps, where the seafloor was about 150 metres (490 feet) deep and had little oxygen.1

It belonged to a group called ophthalmosaurids, which were the last surviving ichthyosaurs before they went extinct.1
