Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. J. Ryan et al. 2012 | Adult-sized supraorbital horn cores are inflated (but not elongated as in Zuniceratops, chasmosaurines, Albertaceratops, and Diabloceratops) and project laterally over the orbit; sub-adult-sized postorbital horn cores have an attenuated pyramidal shape with a slight lateral inflection of the distal one half; posterior parietal bar has a number of accessory epiparietal ossifications that fuse to the posterior and dorsal surfaces and through ontogeny develop as short spines that may fuse along their adjacent margins into larger, irregular masses. They contribute to the substance of P1 and, through fusion, form the composite epiparietal at the P2 loci. The P3 epiparietal is variably developed as a short tongue-like hook or tapered spike that is dorsolaterally oriented. |
