Reference	Diagnosis
G. Peng et al. 2005	Medium-sized ornithopod about 3.2 m of body length. It is recognized by triangular maxilla with a narrow but long dorsal process and a longitudinal lateral ridge; triradial jugal with a extremely ventrally arched ventral margin; broad and Buddha hand-shaped maxillary teeth with developed wear surfaces so that outer side of crowns deeper than its inner side; tooth crown with a short lateral ridge along anterior and posterior margins, but lacking median ridge; platyancoelous cervical centra with obvious ventral keels; amphiplatyan dorsals; scapula with laterally convex shaft; coracoid with an obvious anteroventral ridge; length of humerus same as that of scapula; obviously arched radius less than 2/3 of humerus length; inner distal condyle of femur much bigger than outer one.
R. J. Butler et al. 2008	The mid–posterior cervicals have circular, pit-like depressions developed at the base of their postzygapophyses.
