Name: Diabloceratops (Devil horned face).
Named By: Kirkland et al - 2010.
Classification: Chordata, Reptilia, Dinosauria, Ornithischia, Ceratopsidae, Centrosaurinae.

Fossil representation: Well preserved skull.
Although named in 2010, the skull of Diabloceratops was discovered in 2002. The first thing about the skull of Diabloceratops is that it has two large horns that rise from the top of its neck frill, that then curve slightly to the sides. These 'Devil horns' are the reason why Diabloceratops got its name. The second thing about the skull is that it contains an accessory skull opening. This opening is a common feature amongst basal ceratopsians, but would eventually disappear from later ceratopsaians. This means this skull opening was once a feature of all ceratopsians not just a specific group.
