"Diceratops" is a dubious genus of Ceratopsian that lived in North America during the Late Cretaceous.
Classification[]
"Diceratops" is directly synonymous with "Nedoceratops", which itself is synonymous with Triceratops. "Diceratops" was named alongside Diceratus around the same time, and are based off of a Ceratopsian skull with a short frill, and upturned brow horns. The material holotype this genus is based on has been confirmed to be the same holotype skull that creates the genus Nedoceratops.
Like Nedoceratops; "Diceratops" is about 15 feet long, and weighs about 2-3 tons, and ate plants during the Late Cretaceous in North America. "Diceratops" was authored by Hatcher, and co-authored by Lull, who then published the paper posthumously. Scientists were not sure about the validity of "Diceratops", and suggested it may be a pathological. It was made a subgenus of Triceratops, being published as Triceratops (Diceratops) hatcheri. The subgenus included the species T. (D. ) obtusus, which further solidified the ontogenetic stage theory.
The name was made synonymous due to the name being used in the family Hymenopteran, and was reclassified in 2007 by Andrey Sergeevich Ukrainsky. Unaware that the animal had been named by Ukrainsky, Octávio Mateus erected another dubious genus: "Diceratus".
