Species: C. belli

C. belli is an average sized ceratopsian, known from the late Cretaceous. It is notable for its long, rectangular, and fenestrated frill. Although the edges were interspersed with bony projections, the large openings in the frill would have been covered with skin, and would not have provided the skull with any physical protection. Instead, C. belli may have relied on the horns situated above the eyes and on the snout for any defensive behaviour.

C. belli is also considered to be the exemplar of the Ceratopsinae, or long-frilled, subfamily of ceratopsians.
