Barnum Brown found the first "Anchiceratops" skulls in 1912. He gave them their name, "Anchiceratops ornatus", in 1914, two years later. "Anchiceratops" means "almost "Ceratops"" and "ornatus" means "ornate". In 1924, C. M. Sternberg discovered another skull. It was smaller and had a long beak. In 1929, he named this species "A. longirostris", meaning "long snout." However, in 1990, Leham decided that "A. longirostris" was only the female of "A. ornatus". Another study done by Dodson and Currie in the same year agreed with this idea. In 1925, Sternberg found a headless skeleton that he thought belonged to "Anchiceratops". However, it could belong to "Arrhinoceratops" or a new genus. Other skulls have been found but they have never been described.
