Ojoceratops
''Ojoceratops'' is a genus of ceratopsian dinosaur which lived in what is now New Mexico, United States. ''Ojoceratops'' fossils have been recovered from strata of the Ojo Alamo Formation (Naashoibito Member), dating to the late Cretaceous period (probably Maastrichtian age, 68 million years ago〔Sullivan, R.M., and Lucas, S.G. 2006. "(The Kirtlandian land-vertebrate "age" – faunal composition, temporal position and biostratigraphic correlation in the nonmarine Upper Cretaceous of western North America )." New Mexico Museum of Natural History and Science, Bulletin 35:7-29.〕). The type species is ''Ojoceratops fowleri''. It is very similar to its close relative ''Triceratops'', though it is from an earlier time period and has a more squared-off frill.〔Robert M. Sullivan and Spencer G. Lucas, 2010, "A New Chasmosaurine (Ceratopsidae, Dinosauria) from the Upper Cretaceous Ojo Alamo Formation (Naashoibito Member), San Juan Basin, New Mexico", In: Ryan, M.J., Chinnery-Allgeier, B.J., and Eberth, D.A. (eds.) ''New Perspectives on Horned Dinosaurs: The Royal Tyrrell Museum Ceratopsian Symposium'', Bloomington, Indiana University Press, 656 pp.〕 Nick Longrich, in 2011, noted that the squared-off frill is also found in some true ''Triceratops'' specimens and that ''Ojoceratops'' is probably a junior synonym of ''Triceratops'', while Holtz (2010) noted that it is probably ancestral to ''Triceratops'' and possibly synonymous with the contemporary ''Eotriceratops''.〔Holtz, Thomas R. Jr. (2011) ''Dinosaurs: The Most Complete, Up-to-Date Encyclopedia for Dinosaur Lovers of All Ages,'' (Winter 2010 Appendix. )〕
