       Nedoceratops is a genus of ceratopsian dinosaur that lived in North America in the late Cretaceous.‭ ‬So far only a single skull has been attributed to the genus,‭ ‬but originally this skull was called Diceratops.‭ ‬When this name was found to already be in use however,‭ ‬the name Nedoceratops was given to the skull.‭ ‬One year later Octávio Mateus,‭ ‬then unaware that a new genus had been created,‭ ‬named the skull Diceratus,‭ ‬which is now listed as a synonym to Nedoceratops.‭ ‬In life Nedoceratops would have been a medium to large genus of ceratopsian dinosaur.‭ ‬The name Nedoceratops is a reference to the lack of a nasal horn.
       Nedoceratops is currently seen as a dubious genus with some researchers considering the skull to be valid,‭ ‬while others consider it to belong to an already named genus.‭ ‬Indeed,‭ ‬Nedoceratops got caught up early in the great Triceratops/Torosaurus synonymy debate.‭ ‬This started in‭ ‬2010‭ ‬when John Scanella and John Horner proposed that Torosaurus was the true adult form of Triceratops,‭ ‬and that the holotype skull of Nedoceratops was the link that showed this growth.‭ ‬However,‭ ‬a later study by Andrew Farke showed that the holes in Nedoceratops were probably the result of disease and did not match the form of the holes seen in Torosaurus.‭ ‬At the time of writing Scanella and Horner concede that Nedoceratops is probably not‭ ‘‬the‭’ ‬transitional form that they need to prove their theory,‭ ‬but insist that the holotype skull is of a diseased Triceratops.
