Yueosaurus is an extinct genus of basal ornithopod dinosaur known from Zhejiang Province, China.[1]

Description[edit]

Yueosaurus is known only from the holotype ZMNH M8620, an articulated, partial but well preserved postcranial skeleton which includes cervical, dorsal (back) and caudal vertebrae, scapula, rib, hip bones, partial forelimb and partial hindlimb. It was collected in Tiantai locality from the Liangtoutang Formation, dating to the Aptian-Cenomanian stages of the latest Early Cretaceous and the earliest Late Cretaceous. Yueosaurus represents the southernmost basal ornithopod dinosaur from Asia, and the first one from China. It differs from other ornithischians by a combination of characters.[1] Han et al. found it plausible that Yueosaurus might be a member of Jeholosauridae or closely related to it.[2]

Etymology[edit]

Yueosaurus was first named by Wenjie Zheng, Xingsheng Jin, Masateru Shibata, Yoichi Azuma and Fangming Yu in 2012 and the type species is Yueosaurus tiantaiensis. The specific name refers to the Tiantai, where the holotype was discovered.[1]
