A new ornithischian dinosaur, Yueosaurus tiantaiensis gen. et sp. nov., is
erected based on a partial postcranial skeleton from the Liangtoutang
Formation (Aptian?Cenomanian) of Zhejiang Province, China. It differs from
other ornithischians in possessing the following unique combination of
characters: prominent and slightly ventrally directed cervical
parapophyses; anteroposteriorly narrow neural spines on caudal vertebrae;
scapula with a ventroscapular groove, supraglenoidal buttress, supraglenoid
fossa, and a strong anteroventral expansion of the scapular blade.
Yueosaurus represents the first basal ornithopod taxon from southeastern
China. It expands our understanding of the Cretaceous dinosaurian fauna of
Zhejiang Province.
