Diagnosis
ReferenceDiagnosis
H.-D. Sues and A. Averianov 2009A basal hadrosauroid iguanodontian that differs from known non-hadrosauroid iguanodontians in the following features: ectopterygoid–jugal contact absent; predentary gracile and shovel-shaped, with gently rounded anterior margin; surangular foramen absent; and dentary tooth crowns with one primary ridge and faint (if any) secondary ridges. Differs from Bactrosaurus (Gilmore 1933) in presence of tall sagittal crest on parietals, absence of lacrimal process on prefrontal, and absence of club-shaped neural spines on dorsal vertebrae in adults. Differs from Gilmoreosaurus (Brett-Surman 1979) by shorter contribution of frontal to orbital rim, longer diastema between first dentary tooth and predentary (equivalent to more than one-fifth of tooth row length), and nearly vertical coronoid process of dentary. Differs from more derived Hadrosauroidea in absence of well-developed continuous ectopterygoid ridge on maxilla; dentary tooth row and posterior end of dentary terminating at apex of coronoid process; and dentary tooth row bowed lingually in occlusal view.
