""Ceratops"" is a dubious genus of herbivorous ceratopsian dinosaur which lived during the Late Cretaceous. Its fossils have been found in Montana. Although poorly known, "Ceratops" is important in the history of dinosaurs, since it is the type genus for which both the Ceratopsia and the Ceratopsidae have been named. The material is too poor to be confidently referred to better specimens, and "Ceratops" is thus considered a "nomen dubium". The first remains referred to "Ceratops" — an occipital condyle and a pair of horn cores — were found by John Bell Hatcher in the late summer of 1888 near the Cow Creek in Blaine County in the uppermost Judith River Formation of Montana. Hatcher was at the time employed by Professor Othniel Charles Marsh who the same year named the find as the type species "Ceratops montanus". The generic name was derived from Greek κέρας, "keras", "horn", and ὤψ, "ops", "face". The specific name referred to Montana. Marsh originally believed the animal to be similar to "Stegosaurus", but with two horns on the back of its head, a body length of twenty-five to thirty feet, horizontal plates on its back and bipedal. According to Marsh it would have "represented a very strange appearance". In his illustration of the horn pair, purportedly showing them from behind, Marsh had switched their position and rotated their outside to the rear to make them point inwards. The holotype, "USNM 2411", was found in a layer dating from the Campanian. It consists, apart from the occipital condyle, of two supraorbital horn cores of about twenty-two centimetres length. The right horn is attached to a part of the prefrontal. Marsh later referred two squamosals to the species, specimens USNM 4802 and USNM 2415. These however are more likely centrosaurine; they have also been referred to "Avaceratops". Wiz Science™ is "the" learning channel for children and all ages.
