Diabloceratops

Diabloceratops /daɪˌæbloʊˈsɛrətɒps/ is an extinct genus of centrosaurineceratopsian dinosaur that lived approximately 79 million years ago during the latter part of the Cretaceous Period in what is now Utah, in the United States. Diabloceratops was a medium sized, moderately-built, ground-dwelling, quadrupedal herbivore, that could grow up to an estimated 5.5 m long. At the time of its discovery, it was the oldest known ceratopsid, and first centrosaurine known from latitudes south of the US state of Montana.
