VP 17431 (Everhart, 2009). The left and right dentaries are fused and form a predentary symphysis, which articulates with the predentary. In ventral aspect, the symphysis sits within a small recess, and the two dentaries interdigitate to form a crosshatched pattern with small bulbous ridges. This may be a new feature for

The element is ornamented with a series of strong parallel striations that extend the length of the premaxilla and cover the dorsal and lateral edges. These striations occasionally intersect along the dorsal margin. In ventral view, a shallow sulcus extends medially along the entire length of the premaxilla. This sulcus is V-shaped in posterior view, and it becomes gradually shallower towards the anterior end. Positioned on each lateral side of this sulcus is a single row of minute, tightly packed, alveoli (

The crown on the individual teeth is rounded and lacks a distinct cusp. A pronounced ridge extends medially across the length of the labial and lingual faces of the dentary. The ventral face is composed of a thin crest that also extends the length of the element and forms a distinct Tshaped outline in profile view.
