Cryopterygius was a large, fish-shaped marine reptile that lived in the chilly seas near the North Pole during the Late Jurassic. It was an ichthyosaur, not a dinosaur, and its fossil was dug out of permafrost, which is frozen ground.1

1

The name Cryopterygius means 'cold fin' or 'frozen fin' because it was found in frozen ground in a very cold place.1

2

Its skeleton was nearly complete and still joined together, which is very rare for an ichthyosaur fossil.1

3

Cryopterygius had 52 vertebrae in front of its hips, which is a lot for an ichthyosaur.1

4

Its upper arm bone, the humerus, had only two bumps at the end where it connected to the rest of the fin.1

5

It lived in the Late Jurassic, about 149 to 143 million years ago, in the cold polar seas.4

6

Scientists found a complete left hip and leg, which helped them understand how ichthyosaurs moved their hind fins.1
