Diabloceratops BW

Hypothetical restoration of the ceratopsian.

[[Image:Diabloceratops skull side2.jpg|thumb|left|Sketch of the side view of the skull. Diabloceratops eatoni is a recently discovered species of extinct herbivorous dinosaur in the infraorder ceratopsia that lived during the Campanian stage of the Late Cretaceous epoch. Its fossils were discovered in the Wahweap Formation of Southern Utah.

EtymologyEdit

The genus name combines the Spanish word Diablo, meaning "devil", a reference to the horns on the neck shield, with the Latinised Greek word ceratops, meaning "horned face", a usual element in ceratopsian names. The specific name honours Jeffrey Eaton, a paleontologist at Weber State University and long time friend of the lead author Jim Kirkland. Eaton had a big role in establishing the Grand Staircase-Escalante National Monument where the specimen was found. The type species, Diabloceratops eatoni, was named and described in 2010 by James Ian Kirkland and Donald DeBlieux.

Discovery and occurrenceEdit

Description Edit

Diabloceratops was built like a centrosaurine ceratopsian, whose parietosquamosal frill contained a pair of elongated, slightly curved spikes extending from the top of the parietal . It is more closely related to Einiosaurus and Styracosaurus (also centrosaurines) than it is to Chasmosaurus, Pentaceratops, or Triceratops (chasmosaurine ceratopsians).

Upon the frill it also had a pair of very long spikes as in Einiosaurus and Styracosaurus. It being one of the earliest centrosaurine ceratopsids, Kirkland noted a character Diabloceratops shared with the more "primitive" protoceratopsid forms. Both possess an accessory opening in the skull that would become much reduced or disappear in later, more advanced ceratopsids. Kirkland saw this as an indication that the earlier species were not together included in some single natural group but instead presented a gradual sequence of ever more derived forms, increasingly closer related to the Ceratopsidae.
