Diagnosis
ReferenceDiagnosis
W. Zheng et al. 2012A small ornithischian dinosaur distinguished by the following unique combination of characters including autapomorphies (marked*) within basal Ornithopoda: prominent and slightly ventrally directed cervical parapophyses; slender and posteriorly inclined caudal neural spines; *anteroventral expansion of the scapula exceeds its posteroventral expansion, and its posterior edge is almost perpendicular to the shaft; *scapula bears a distinctive ventroscapular groove; *scapula also possesses both a supra-glenoidal buttress and supraglenoid fossa; distal fibula anteroposteriorly compressed and tightly appressed to the tibia.
