Changchunsaurus (meaning "Changchun lizard") is an extinct genus of small herbivorous neornithischian dinosaur from Early or Late Cretaceous deposits of Gongzhuling, Jilin, China. It is the first named dinosaur genus from that region.
==Description== Changchunsaurus was first named by Zan Shu-Qin, Chen Jun, Jin Li-Yong and Li Tao in 2005. The type and only known species is C. parvus ("parvus" meaning "petite"), named for its small size. It is known from a skull and skeleton and additional skull fragments. All specimens of Changchunsaurus were collected from the Quantou Formation of the Songliao Basin, dating to the Aptian–Cenomanian stages. Changchunsaurus is based on the holotype JLUM L0403-j–Zn2, a skeleton and skull, with a premaxilla (upper beak) and partial lower jaw also known. Only the skull was figured and described in the official description.
