Shenzhou is the ancient name of China; orientalis refers to the east. Material: A partial skeleton preserved on a sandstone block in a death pose with its head above the torso. The distal hindlimbs, distal tail, and the forelimbs (except for part of the right hand) and the pectoral girdle are missing. The head is crushed, exposing the left side obliquely.
An ornithomimosaur distinguishable from all others except Harpymimus in having teeth restricted to the anterior sentarys... primitive characters not found in advanced ornithomimosaurs, like a straight ischium and a postacetabular process that is gently curved rather than truncated... distinguishable from Pelecanimimus by the tooth distribution pattern and the primitive configuration of the hand where digit I is shorter than digits II and III.
