Therizinosauria

Life reconstruction of Jehol therizinosaurians, illustrating variation in body size, skeletal proportions and inferred ecological strategies among species (from bottom to top): Lingyuanosaurus sihedangensis is shown in a posture suggesting greater cursoriality; Jianchangosaurus yixianensis is depicted engaging in lingual-assisted feeding, consistent with its robust hyoid apparatus; Beipiaosaurus inexpectus exhibits a robust, less cursorial bauplan; and Kayrasaurus changliensis is reconstructed browsing on higher vegetation, reflecting its larger body size and inferred feeding strategy

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.
