The mesorostral groove is completely filled with the vomer. The dorsal surface of the latter becomes progressively keeled from mid-length of the rostrum in the posterior direction and a longitudinal sulcus marks the right and left vomer-premaxilla contacts. A median suture is visible on the posterior half of the vomer in the mesorostral groove. The vomer-presphenoid suture is transversely directed, located at a level posterior to the premaxillary foramen. Deep longitudinal openings on the lateral surfaces of the rostrum most likely result from partial wear of superior alveolar canals. The shallow groove appearing ventral to these openings in the anterior half of the rostrum is probably a vestigial alveolar groove. The lateral margin of the rostrum raises posterodorsolaterally, forming a robust ridge that laterally defines a medial depressed area made of the premaxillae and vomer. No distinct prominential notch being present, the ridge joins the elevated, dome-like rostral maxillary crest, the latter being posterior and slightly medial to the widely open and relatively deep antorbital notch. The right rostral maxillary crest is transversely narrower than the left, slightly higher, and extends more posteriorly. A large dorsal infraorbital foramen is anteromedial to each rostral maxillary crest.</paragraph>

At its maximum width, the premaxillary sac fossa is transversely concave. The relatively short ascending process of premaxilla displays an abrupt elevation, with its anterior surface becoming roughly vertical in its upper part; the left process is slightly less erected. Right and left ascending processes display a strong transverse constriction as seen in anterior view. Each premaxillary crest is directed laterally and slightly posterolaterally, with a curve more pronounced on the slightly longer right crest. The nasals occupy a large area on the vertex, with the right nasal longer and wider than the left. The anteromedial tip of the joined nasals reaches the same anteroposterior level as the anterior margin of the premaxillary crests. The anterodorsal margin of each nasal is excavated by a wide, subvertical groove, best seen in dorsal view. The dorsal surface of the nasals displays a slight medial depression and anteromedial slope. The contribution of each nasal to the corresponding premaxillary crest is minor.</paragraph>
