Therizinosauria

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.

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.
