Cryptoclidus was a medium-sized plesiosaur that swam in warm seas during the Middle and Late Jurassic. It had a small head, a long neck, and four flippers. It probably ate soft animals like squid and small fish.1

Dintlha tse di monate

The name Cryptoclidus means 'hidden collarbone' because its collarbones are tiny and hidden in the shoulder area.1

Fossils of Cryptoclidus have been found in the Oxford Clay of Cambridgeshire, England, and in the Kimmeridge Clay of France.1

The type species was first called Plesiosaurus eurymerus, which means 'wide thigh bone', because scientists mistook a front flipper bone for a back leg bone.1

Cryptoclidus had a small, fragile skull and teeth that could not handle tough prey, so it ate only soft animals.1

Scientists think Cryptoclidus used its long, intermeshing teeth to strain small animals from the water or sift through mud.1

The size and shape of its nostrils suggest Cryptoclidus could smell chemicals in seawater, helping it find food.1

Complete skeletons of Cryptoclidus have been found, including some that are nearly entirely preserved, showing both adults and juveniles.1

?Was Cryptoclidus a dinosaur?

No, it was a plesiosaur, which is a marine reptile that lived in the sea. It is not a dinosaur.1

?When did Cryptoclidus live?

It lived during the Middle and Late Jurassic Period, about 166 to 160 million years ago.1

?Where were Cryptoclidus fossils found?

Fossils have been found in England, France, Cuba, and Russia. Many come from the Oxford Clay in Cambridgeshire, England.1 2

?Could Cryptoclidus swim?

Yes, it was a good swimmer. It used its four flippers to move through warm Jurassic seas.1
