名字的意思： “Bishan lizard”5

吃：肉蛇頸龍類侏羅紀早期到侏羅紀晚期嚴格來說不是恐龍

Bishanopliosaurus was a short-necked plesiosaur that lived in a warm, freshwater lake in China. It was a fierce hunter, using its long jaws and sharp teeth to catch fish and other prey. Even though it lived in water, it was not a dinosaur but a marine reptile.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。

趣味知識

Bishanopliosaurus is one of the most complete plesiosaur fossils ever found in Asia from the Jurassic period.1

It had a short neck and a long body, with at least 17 neck bones, 19 back bones, 3 hip bones, and 26 tail bones.2

Its sacral ribs (ribs near the hips) were split into two branches, a unique feature that helps identify it.2

The type specimen was a young individual, so adults might have been larger than 4 metres long.1

Bishanopliosaurus lived in a subtropical freshwater lake, which is unusual because most plesiosaurs lived in the sea.1

Its name means 'Bishan lizard' after the county in China where it was found.5

Scientists are not sure exactly how old the rocks are that contained Bishanopliosaurus, so it could be from the Early or Middle Jurassic.1
