The nasals occupy a large nearly rectangular surface on the wide and low vertex, much longer than the short strip of frontals (complete on SAM PQ2339), and wider than long. The lateral margin of the nasal is moderately convex and its anterolateral corner forms only a small part of the premaxillary crest. A vertical groove excavates the anterior margin of each nasal and the rounded anterior point of the nasals is only slightly more anterior than the premaxillary crests. The naso-frontal suture is roughly rectilinear. The morphology of the posterior portion of the vertex is not as well preserved as in
