Eotriceratops BW.jpg

Eotriceratops (meaning "dawn Triceratops") is a genus of ceratopsian dinosaurs which lived during the late Cretaceous period. Fossils of the only known species, Eotriceratops xerinsularis, have been found in the uppermost Horseshoe Canyon Formation, dating to about 67.6 million years ago. Possible additional specimens, which have been variously classified in the species Ojoceratops fowleri and Torosaurus utahensis, are known from the same time period in New Mexico and may also belong to Eotriceratops. The largest known skull is reported to have been around 3 metres (10 ft) long. It has been estimated that this specimen had a total length of about 9 meters (30 ft), making it the second-largest ceratopsian, after Titanoceratops.
