Diabloceratops (from ancient Greek Διάβολος Diábolos 'devil', κέρας kéras 'horn' and ὤψ ōps 'face'; literally meaning 'face with devil's horns') was a genus of bird basin dinosaurs (Ornithischia) from the group of Ceratopsia . The herbivore Diabloceratops lived in North America, where he in 2002 Wahweap Formation in the area of Grand Staircase-Escalante National Monument in the US - state of Utah was discovered. The holotype specimen consists of an almost completely preserved skull. Another fragmentary skull could also belong to this genus.

Artistic reconstruction of life

features

Diabloceratops reached a length of about 3.5 meters and a height of 1.2 meters, its weight is estimated at 150 kilograms.

The most striking feature is its ruff and curved horns head, from which it owes its name.

Systematic position of Diabloceratops according to Evans & Ryan (2015).

Diabloceratops is one of the Ceratopsidae . In 2015, the family tree of the Centrosaurinae was revised by Evans & Ryan (2015) on the occasion of the first description of the Wendiceratops found in Canada . Accordingly, Diabloceratops is the most basal genus and the sister taxon of all other known Centrosaurinae, followed by a common taxon from Nasutoceratops and Avaceratops . In a phylogenetic analysis in 2012, Xenoceratops was considered the most basal genus of the Centrosaurinae and compared to all other known genera including the Diabloceratops .
