Etymology: "Ceratops" is a modern scientific coinage, not an ancient word. It was formed in the 1880s from Greek "keras" (horn) and "ops" (face), so it literally means "horned face." The Greek roots are classical, but the name itself dates from the paleontology of the late nineteenth century, when fossil hunters in the American West were uncovering horned dinosaurs and needed names for them. The name was first applied to the genus Ceratops, described by the American paleontologist Othniel Charles Marsh in 1888 from fossils found in Montana. Marsh's choice of a face-based name reflected the animal's most striking features: a beaked skull crowned with horns above the eyes and nose. The family-level term Ceratopsia, and later Ceratopsidae, were built on the same stem, which is why the word now covers a whole group of related dinosaurs rather than a single species.
