Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. M. Sullivan et al. 2011 | Lambeosaurines distinguished from parasaurolophines by the following features: premaxilla has a vertical groove on the caudolateral process rostral to the maxillary dorsal process that extends vertically from a small lateral opening between the premaxillary caudal processes; nasal vestibule morphology consists of an S-loop in the enclosed premaxillary passages rostral to the dorsal process of the maxilla; and 13 or fewer cervical vertebrae present (characters 5, 8, and 66, respectively, of Evans and Reisz, 2007). | |
| A. Prieto-Marquez et al. 2013 | Lambeosaurine hadrosaurids possessing vertical groove on lateral process of premaxilla, located rostral to dorsal process of maxilla and extending ventrally from small opening between premaxillary medial and lateral processes; vertical groove bounded rostrally by triangular ventral projection of lateral process of the premaxilla; nasal articulation surface for frontal shaped into rostroventrally-sloping platform; nasal vestibule folded into S-loop in enclosed premaxillary passages rostral to dorsal process of maxilla; and lateral premaxillary process extending caudodorsal to prefrontal in adults. |
