Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| A. T. McDonald et al. 2010 | For genus and species by monotypy. Non-hadrosaurid hadrosauroid characterized by two autapomorphies: highly vascularized, rugose texture covering entire lateral surface of postorbital (from orbital rim to at least the base of squamosal process) and large neurovascular foramen at base of jugal process of postorbital. Also diagnosed by the following combination of characters: extremely slender dentary (rostrocaudal length/depth at midpoint ratio = 5.6), coronoid process with strong rostral expansion, high number (32) of tooth alveoli in dentary, caudal extent of dentary tooth row is even with apex of coronoid process, at least two replacement teeth per dentary alveolus, asymmetrical tooth crowns, reduced accessory ridge on either side of primary ridge on dentary tooth crowns, lack of accessory ridges on maxillary tooth crowns, and paraquadrate foramen present. |
