Median teeth are wider than long; those in upper dentition have a very convex occlusal surface and sinuous to arcuate (convex labially) occlusal outline. Labial and lingual crown foot straight. Teeth in lower dentition with flat occlusal surface; occlusal outline sinuous or arcuate. In labial and lingual views, crown is thickest medially; crown foot is convex and tapers toward the distal margins. Labial crown face of median teeth weakly concave; generally inclined lingually, but at times near vertical. Lingual face with reticulated ornamentation; forms network of fine pits across the surface. Less worn teeth show the ornamentation may have longitudinal component apically (that is obliterated as the crown is worn through

use). Labial crown face weakly convex, usually lingually inclined, may be nearly vertical. Lingual face ornamented with interconnected beaded ridges. Median teeth with rounded, strongly obtuse lateral angles; intersection of labial and lingual parts of the angle located closer to the anterior or posterior crown margin, depending on tooth position. Labial crown foot overhangs the root; lingual face bears thin and sharp transverse lingual ridge at the boundary between the crown and root. Root is low; labial face strongly inclined basiolingually; lingual margin extends beyond the crown foot. Root of median teeth polyaulocorhize, subdivided into numerous thin lamellae.

MSC 35808 is an upper dentition consisting of nine articulated median teeth, with the remnants of an additional (tenth) tooth preserved on the labial face of the anterior-most tooth. This specimen, as well as all the available upper dentitions, shows that the entire upper dentition was a convex plate. Median teeth in the labial portion of the dentition have a sinuous occlusal outline, whereas the outline becomes more arcuate towards the back of the mouth. Although teeth are thickest medially, the crown tapers laterally to a very short and thin shelf. Although no complete lateral teeth are preserved on specimen MSC 20988.5, a part of a lateral tooth row is preserved on one side. A second lateral row is indicated by distal articular surfaces on teeth in the first lateral row. MSC 33956 consists of two articulated median teeth, both of which have very convex occlusal surfaces, that we interpret as having formed part of an upper dentition.</paragraph>
