Ceratopian
Ceratopsia or Ceratopia ( or ; Ancient Greek, Greek: "horned faces") is a group of herbivore, herbivorous, beaked dinosaurs that thrived in what are now North America, Europe, and Asia, during the Cretaceous Period (geology), Period, although ancestral forms lived earlier, in the Jurassic. The earliest known ceratopsian, ''Yinlong downsi'', lived between 161.2 and 155.7 million years ago.Holtz, Thomas R. Jr. (2011) ''Dinosaurs: The Most Complete, Up-to-Date Encyclopedia for Dinosaur Lovers of All Ages,'Winter 2010 Appendix./ref> The last ceratopsian species, ''Triceratops prorsus'', became extinct during the Cretaceous–Paleogene extinction event, . ''Triceratops'' is by far the best-known ceratopsian to the general public. It is traditional for ceratopsian genus names to end in "''-ceratops''", although this is not always the case. One of the first named genera was ''Ceratops'' itself, which lent its name to the group, although it is considered a ''nomen dubium'' today as its fo ...

Kulceratops
''Kulceratops'' is a genus of ceratopsian dinosaur from the Early Cretaceous. It lived in the late Albian stage. It is one of the few ceratopsians known from this period. However, the fossils from this genus have been sparse: only jaw and tooth fragments have been found so far. Description ''Kulceratops'' was named by Lev Alexandrovich Nesov in 1995.L. A. Nessov, 1995, ''Dinozavri severnoi Yevrazii: Novye dannye o sostave kompleksov, ekologii i paleobiogeografii'', Institute for Scientific Research on the Earth's Crust, St. Petersburg State University, St. Petersburg pp. 1-156 The type species is ''Kulceratops kulensis''. Both the genus name and the specific name are derived from the Khodzhakul Formation, ''kul'' meaning "lake" in Uzbek. Its fossils were found in Uzbekistan, central Asia. The holotype, CCMGE No. 495/12457, was in 1914 discovered by geologist Andrei Dmitrievich Arkhangelsky. It consists of a left maxilla, of which the front end has been broken off. Classi ...
