Diagnosis
ReferenceDiagnosis
X. Pereda-Suberbiola et al. 2009Lambeosaurine hadrosaurid characterized by a very prominent frontal dome, more developed than in other adult specimens; nearly vertical prequadratic process of the squamosal and jugal process of the postorbital; deltopectoral crest of the humerus oriented anteriorly. Differs from other lambeosaurines in having a unique combination of characters: short frontal, with a posterior length/with ratio estimated at 0.5; midline ridge of parietal approximately at the level of the postorbital-squamosal bar; parietal not interposed between the squamosals in the occipital surface of the skull; lateral side of squamosal relatively low above the cotyloid cavity.
