Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. J. Ryan et al. 2012 | Unescoceratops, gen. nov. differs from Cerasinops, Leptoceratops, Prenoceratops, Udanoceratops, and Zhuchengceratops in having a gentle rather than pronounced curvature of the ventral margin of the dentary, and from Montanoceratops, which has a straight ventral margin. Unescoceratops shares with Leptoceratops and Prenoceratops the flange-like anteroventral margin of the predentary-dentary symphysial surface, but differs from them in having this flange developed as a small “chin” projecting below the ventral margin. Additionally, in Prenoceratops, the flange is separated from the ventral margin by a notch. Unescoceratops is similar to Leptoceratops, Montanoceratops, and Zhuchengceratops in having a dentary that is deeper anteriorly than it is posteriorly (Chinnery and Weishampel, 1998), but the presence of the chin gives its dentary a distinct hatchet-shape when viewed laterally. Unescoceratops shares with Cerasinops a distinctly recumbent coronoid process, but it can be differentiated from this taxon in having the contacts for the surangular and articular being positioned more posteriorly below the coronoid process. It differs from all other leptoceratopsids for which the teeth are known in that the teeth from the middle region of the dentary are as wide as high and have a rounded lingual profile with marginal denticles that extend almost to the root. The dentary teeth of other leptoceratopsids are much taller than wide, have vertical mesial edges, with the denticles on the mesial edge restricted to the top of the tooth. |
