Therizinosauria

Kayrasaurus is a therizinosaurian dinosaur that lived during the Early Cretaceous period in what is now China. At an estimated 3.6 m in total body length, it is the largest therizinosaur known from the Jehol Biota. Like other therizinosaurs, Kayrasaurus was a bipedal herbivore with large curved claws on each hand.

Reconstitution des thérizinosauriens de Jehol, illustrant les variations de taille corporelle, de proportions et de stratégies écologiques supposées entre les espèces (de bas en haut) : Lingyuanosaurus sihedangensis représenté dans une posture suggérant une plus grande aptitude à la course. Jianchangosaurus yixianensis représenté en train de se nourrir à l’aide de sa langue. Beipiaosaurus inexpectus présentant une morphologie robuste et moins adaptée à la course et Kayrasaurus changliensis reconstitué en train de brouter de la végétation plus haute, ce qui reflète une plus grande taille et une stratégie alimentaire différente.
