gauza bikainak

Datu dibertigarriak

Kayrasaurus had more teeth in its lower jaw than any other therizinosaur known.1

Its neck vertebrae were much longer than its back vertebrae, giving it a long neck.2

The claws on its hands were large and strongly curved, probably used for gathering plants or defense.1

The only known fossil is a nearly complete skeleton, but it is missing the legs and most of the pelvis.1

Kayrasaurus was about 1.6 times larger than its relative Beipiaosaurus, which lived at the same time and place.2

The fossil was flattened into nearly two dimensions, like a pancake, during the process of fossilization.1
