Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| D. C. Evans and R. R. Reisz 2007 | Lambeosaurine hadrosaurid that has the following autapomorphies: crest procumbent with a crestsnout angle less than 110 degrees; caudal margin of crest formed predominantly by the premaxilla (with the nasal contributing to the lateroventral region of a solid caudal process); rostral nasalcaudodorsal process of premaxilla (pml) joint in which the nasal fits along ventral edge of the premaxilla; premaxilla caudodorsal process with accessory ventral flange that overlaps the nasal in the rostral region of the crest (convergently evolved in Hypacrosaurus altispinus); complete enclosure of trie ophthalmic canal of the laterosphenoid. Differs from Corythosaurus and Hypacrosaurus in three features of the crest: 1) the caudodorsal and caudolateral processes of the premaxilla are expanded rostrally and the apex of the crest occurs rostral to the orbit, 2) the nasal forms a relatively small contribution to the external crest surface, 3) caudodorsal process of the premaxilla extends to the caudalmost limit of the crest. |
