Kimmerosaurus

Kimmerosaurus ("lizard from Kimmeridge") is an extinct genus of plesiosaur from the family Cryptoclididae. It is known from remains found in England and Norway.

==Discovery and naming== There are very few fossil remains of Kimmerosaurus known. In fact, nothing has been found to show what Kimmerosaurus may have looked like below the neck, although the atlas and the axis are similar to those of the plesiosaur Colymbosaurus. It is this lack of any post-cranial fossils, and the bone similarities that has led to the belief that Kimmerosaurus fossils could be the missing head of Colymbosaurus, a similar plesiosaur with no known skull fossils.
