History

The first remains referred to Ceratops (an occipital condyle and a pair of horn cores) were found by John Bell Hatcher (1861-1904) in the summer of 1888 in the Judith River Formation of Montana. John Bell Hatcher ( October 11, 1861 &ndash July 3, 1904) was an American Paleontologist and fossil hunter best known The Judith River Formation is a Fossil -bearing Geologic formation in northern Montana, and is part of the Judith River Group. O. C. Marsh originally believed the animal to be similar to Stegosaurus, but with two horns on its head. Othniel Charles Marsh ( October 29, 1831 &ndash March 18, 1899) was one of the pre-eminent Paleontologists of the 19th century who Stegosaurus (ˌstɛgəˈsɔrəs is a Genus of stegosaurid armoured Dinosaur from the Late Jurassic period (

Classification

Ceratops belonged to the Ceratopsia (the name is Ancient Greek for "horned face"), a group of herbivorous dinosaurs with parrot-like beaks which thrived in North America and Asia during the Cretaceous Period, which ended roughly 65 million years ago. The Ancient Greek language is the historical stage in the development of the Hellenic language family spanning the Archaic (c Parrots are birds of the roughly 350 Species in 85 genera comprising the order Psittaciformes, found in most warm and tropical regions The Cretaceous (kriːˈteɪʃəs, usually abbreviated 'K' for its German translation "Kreide" is a geologic period and system, reaching from the end of It is the first named member of the subfamily popularly known as Chasmosaurinae which has been renamed Ceratopsinae under ICZN rules.

In 1999, Penkalski and Dodson concluded Ceratops is a nomen dubium because the material is too meager. In zoological nomenclature, a nomen dubium ( Latin for "doubtful name" plural nomina dubia) is a scientific name that is They add that Avaceratops appears closely related and may even be a juvenile Ceratops but there is just not enough material to prove it. Avaceratops is a Genus of small Ceratopsian Dinosaur which lived during the late Campanian during the Late Cretaceous

Diet

Ceratops, like all Ceratopsians, was a herbivore. Herbivory is a form of Predation in which an Organism, known as a herbivore, consumes principally Autotrophs ref name=Campbell>Campbell During the Cretaceous, flowering plants were "geographically limited on the landscape", and so it is likely that this dinosaur fed on the predominant plants of the era: ferns, cycads and conifers. The Cretaceous (kriːˈteɪʃəs, usually abbreviated 'K' for its German translation "Kreide" is a geologic period and system, reaching from the end of A fern is any one of a group of about 20000 Species of Plants classified in the phylum or division Pteridophyta, also known as Filicophyta Cycads are a group of Seed plants characterized by a large crown of compound leaves and a stout trunk. It would have used its sharp Ceratopsian beak to bite off the leaves or needles.
