Diagnosis
ReferenceDiagnosis
R. L. Nydam and B. M. Fitzpatrick 2009Differs from Contogenys ekalakaensis sp. nov. in the following combination of dentary features: more gracile subdental shelf; intramandibular septum extending posteriorly to penultimate tooth position; ventralmost portion of coronoid facet on coronoid process directed anteroventrally; greater degree of hypertrophy of Meckelian canal results in more pronounced, shelf-like lateral expansion along posterior portion of dentary; and tooth crowns lacking striae.
