On the only known skull, the rostrum was probably relatively short, not much longer than the preserved length. It is somewhat wider than high along its anterior half and as wide as high posteriorly. The mesorostral groove is filled by the vomer, with a median suture on the posterior half. The ventral margin of the alveolar groove, lacking marks of alveoli, extends to the antorbital notch; contrary to

The rostrum base lacks a prominental notch; the antorbital notch is wide and probably shallow, at the level of the premaxillary foramen and slightly anterior to the small maxillary foramen lying along the premaxilla-maxilla suture. Posterior to the antorbital notch, a low maxillary crest thickens the preorbital process, with a lateral slope similar to
