Diagnosis
ReferenceDiagnosis
J. Leidy 1870Crowns of the teeth tuberculate at their enameled margins.
A. Prieto-Márquez 2011Basal hadrosaurid dinosaur characterized by the unique combination of the following plesiomorphic humeral and derived iliac characters within the context of Hadrosauroidea as defined by Prieto-Márquez (2010): very short pectoral crest, being only slightly over 40 per cent of the total length of the humerus; deltopectoral crest expanding smoothly from the humeral shaft, so that its laterodistal corner displays a wide and arcuate profile; ventral apex of supraacetabular crest located above the posteroventral corner of lateral ridge on posterior tuberosity of ischial peduncle of ilium; anteroposteriorly shortened supraacetabular crest, its breadth being half the length of central iliac plate.
