Diabloceratops (Dee-ab-low-seh-rah-tops), Devil horned-face, lived in the early Campanian of the Late Cretaceous of North America. Unlike most other centrosaurine ceratopsians it lived further south. This southern fauna had two different types of hadrosaur, two ceratopsians and a theropod. Diabloceratops is one of the oldest centrosaurines from southern USA, with it appears to be most closely related to Albertaceratops. It looked like most centrasaurines with its short frill.



Genera and Species

Classification: Marginocephalia, Ceratopsia, Ceratopsidae, Centrosaurinae.

Species: D. eatoni


Diabloceratops had big round nose, long horns above its eyes, and spiked frill. There were 2 long parietal horns, 2 postorbital horns and a small nose horn. In North America the horned dinosaurs are divided into two broad groups the chasmosaurs (Chasmosaurus, Triceratops) and centrosaurs like Diabloceratops. Centrosaurs had solid relatively short frills with large nasal horns or bosses. Brow horns are small or nonexistent but frill can be decorated with hornlets and spikes. They are often found in large bone beds.


Length 4 - 5 m (12 - 15 ft).

Weight 1.3 tons.


It was an herbivore. Large bone beds found in Montana of related species indicate that at least seasonally they must have migrated in large herds.

History of Discovery

Discovered by DeBlieux in 2002 known from two fossils.


Found in North America southern Utah and northern Arizona in lakes, floodplains, and east-flowing rivers a wet, seasonal climate.
