Discovery and naming

Skeletal diagram showing known remains

The type species Chuandongocoelurus primitivus was first described and named by Chinese paleontologist He Xinlu in 1984.[1]

Chuandongocoelurus was based on two partial skeletons. The holotype, a thighbone, is part of specimen CCG 20010. Vertebrae, pelvic bones and hindlimb elements, also catalogued under this inventory number, may belong to the same individual. Chaundongocoelurus was a close relative of Elaphrosaurus[2]

The thighbone of C. primitivus has a length of 20.1 cm.[1]
