Kimmerosaurus

名字的意思： “lizard from Kimmeridge”1

吃：肉蛇頸龍類侏羅紀晚期嚴格來說不是恐龍

Kimmerosaurus was a plesiosaur, a long-necked marine reptile that swam in the Jurassic seas. It had a broad skull and sharp, curved teeth for catching fish. Only its skull and a few neck bones have been found, so scientists are still guessing what the rest of its body looked like.1 2

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

Kimmerosaurus is known from only a few skulls and neck bones. No one has found its flippers, tail, or body.1

Some scientists think Kimmerosaurus might actually be the missing head of another plesiosaur called Colymbosaurus, because their neck bones look alike.1

The first Kimmerosaurus fossil was a partial skull found in 1976 by Peter Langham on the Jurassic Coast of England.1

Kimmerosaurus had 8 teeth in its upper jaw and 36 teeth on each side of its lower jaw, all sharply pointed.1

The most complete specimen was discovered on March 7, 2015, and includes the skull roof, brain case, teeth, and vertebrae.1

Kimmerosaurus lived about 152 to 147 million years ago, during the Late Jurassic period.1 2

發現: Kimmerosaurus was named by D. S. Brown in 1981 based on a partial skull found in Dorset, England, in 1976 by Peter Langham. The name comes from the Kimmeridge Clay where it was found.1 2
仍有爭議: Scientists are not sure what the rest of Kimmerosaurus's body looked like. Some think it might be the same animal as Colymbosaurus, but no one knows for certain.1
