Coahuilaceratops
''Coahuilaceratops'' (meaning "Coahuila horn face") is a genus of herbivorous ceratopsian dinosaur. It is a chasmosaurine ceratopsian which lived during the Late Cretaceous period (late Campanian stage) in what is now southern Coahuila in northern Mexico. It is known from the holotype CPC 276, a partial skeleton of an adult individual which includes several skull elements. Another specimen, CPS 277, may represent a juvenile ''Coahuilaceratops''. All specimens of ''Coahuilaceratops'' were collected from a single location in the middle strata of the Cerro del Pueblo Formation, which dates to between 72.5 and 71.4 million years ago.Loewen, M.A., Sampson, S.D., Lund, E.K., Farke, A.A., Aguillón-Martínez, M.C., de Leon, C.A., Rodríguez-de la Rosa, R.A., Getty, M.A., Eberth, D.A., 2010, "Horned Dinosaurs (Ornithischia: Ceratopsidae) from the Upper Cretaceous (Campanian) Cerro del Pueblo Formation, Coahuila, Mexico", In: Michael J.

Bravoceratops
''Bravoceratops'' is a genus of large chasmosaurine ceratopsid dinosaur that lived approximately 70 million years ago, and is known from the Late Cretaceous Javelina Formation in what is now Texas, United States. Discovery and naming ''Bravoceratops'' is only known from the holotype specimen Texas Memorial Museum, TMM 46015-1; it is housed in the collection of the Texas Memorial Museum, Austin, Texas. The skull consists of a number of fragments, altogether including: the , parts of each brow horn, the rear end of the left , assorted parts of the nasal area and horn, the , and quadratojugals from each side, a section of the and , multiple parts of the dentary, and some of the right . It was recovered from the lowermost rocks of the Javelina Formation, in Big Bend National Park; ceratopsid fossils are uncommon in this formation, giving the discovery of ''Bravoceratops'' importance in clarifying the groups' diversity.

Chasmosaurinae
Chasmosaurinae is a subfamily of ceratopsid dinosaurs. They were one of the most successful groups of herbivores of their time. Chasmosaurines appeared in the early Campanian, and became extinct, along with all other non-avian dinosaurs, during the Cretaceous–Paleogene extinction event. Broadly, the most distinguishing features of chasmosaurines are prominent brow horns and long frills lacking long spines; centrosaurines generally had short brow horns and relatively shorter frills, and often had long spines projecting from their frills. Chasmosaurines evolved in western North America (Laramidia). They are currently known definitively from rocks in western Canada, the western United States, and northern Mexico. They were highly diverse and among the most species-rich groups of dinosaurs, with new species frequently described. This high diversity of named species is likely a result of the frill. The distinctive shape of the frill with the hornlets on its edges (epoccipitals) make ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Utahceratops Gettyi
''Utahceratops'' is an extinct genus of ceratopsian dinosaur that lived approximately 76.4~75.5 million years ago during the Late Cretaceous period in what is now Utah. ''Utahceratops'' was a large-sized, robustly-built, ground-dwelling, quadrupedal herbivore, that could grow up to an estimated long. Discovery The genus name ''Utahceratops'', means "horned face from Utah", and is derived from the state of Utah and Greek words "keras" (κέρας) meaning "horn" and "ops" (ὤψ) referring to the "face". The specific name ''gettyi'', is derived from the name of Mike Getty, who discovered the holotype and has played a pivotal role in the recovery of fossils from the Grand Staircase–Escalante National Monument (GSENM). It was first named by Scott D. Sampson, Mark A. Loewen, Andrew A. Farke, Eric M. Roberts, Catherine A. Forster, Joshua A. Smith and Alan L. Titus in 2010, and the type species is ''Utahceratops gettyi''. Description The holotype specimen UMNH VP 16784, consists ...

Mojoceratops Perifania
''Chasmosaurus'' ( ) is a genus of ceratopsid dinosaur from the Upper Cretaceous Period of North America. Its name means 'opening lizard', referring to the large openings ( fenestrae) in its frill (Greek ''chasma'' meaning 'opening' or 'hollow' or 'gulf' and ''sauros'' meaning 'lizard'). With a length of and a weight of , ''Chasmosaurus'' was a ceratopsian of average size. Like all ceratopsians, it was purely herbivorous. It was initially to be called ''Protorosaurus'', but this name had been previously published for another animal. All specimens of ''Chasmosaurus'' were collected from the Dinosaur Park Formation of the Dinosaur Provincial Park of Alberta, Canada. Referred specimens of ''C. russelli'' come from the lower beds of the formation while ''C. belli'' comes from middle and upper beds. Discovery and species In 1898, at ''Berry Creek'', Alberta, Lawrence Morris Lambe of the Geological Survey of Canada made the first discovery of ''Chasmosaurus'' remains; holotype NMC ...

Kosmoceratops Richardsoni
''Kosmoceratops'' () is a genus of ceratopsid dinosaur that lived in North America about 76–75.9 million years ago during the Late Cretaceous period. Specimens were discovered in Utah in the Kaiparowits Formation of the Grand Staircase–Escalante National Monument in 2006 and 2007, including an adult skull and postcranial skeleton and partial subadults. In 2010, the adult was made the holotype of the new genus and species ''Kosmoceratops richardsoni''; the generic name means "ornate horned face", and the specific name honors Scott Richardson, who found the specimens. The find was part of a spate of ceratopsian discoveries in the early 21st century, and ''Kosmoceratops'' was considered significant due to its elaborate skull ornamentation. ''Kosmoceratops'' had an estimated length of and a weight of . As a ceratopsid, it would have been quadrupedal with a heavily constructed skeleton. It had a triangular beak with a pointed tip and a blade-like nasal horn with a flattened upp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vagaceratops Irvinensis
''Vagaceratops'' (meaning "wandering (''vagus'', Latin) horned face", in reference to its close relationship with ''Kosmoceratops'' from Utah) is a genus of herbivorous ceratopsian dinosaur. It is a chasmosaurine ceratopsian which lived during the Late Cretaceous period (late Campanian) in what is now Alberta. Its fossils have been recovered from the Upper Dinosaur Park Formation. It is sometimes included in the genus ''Chasmosaurus'' as ''Chasmosaurus irvinensis'' instead of being recognized as its own genus. Description ''Vagaceratops'' was a medium-sized ceratopsian, reaching in length and weighing . It is known primarily from three fossil skulls. Although the general structure was typical of ceratopsids (i.e. a parrot-like beak, large neck frill, and nasal horn) it has some peculiarities. The skulls are characterized by a reduced supraorbital horn, brow horns that are reduced to low bosses and a larger snout compared to related animals. ''Vagaceratops'' had smaller pariet ...

Triceratops
''Triceratops'' ( ; ) is a genus of herbivore, herbivorous Chasmosaurinae, chasmosaurine Ceratopsidae, ceratopsid dinosaur that first appeared during the late Maastrichtian stage of the Late Cretaceous Period (geology), period, about 68 million years ago in what is now North America. It is one of the last-known non-avian dinosaur genera, and became extinct in the Cretaceous-Paleogene extinction event, Cretaceous–Paleogene extinction event 66 million years ago. The name ''Triceratops'', which literally means 'three-horned face', is derived from the Ancient Greek, Greek words () meaning 'three', () meaning 'horn', and () meaning 'face'. Bearing a large bony neck frill, frill, three horn (anatomy), horns on the skull, and a large four-legged body, exhibiting convergent evolution with rhinoceroses and bovines, ''Triceratops'' is one of the most recognizable of all dinosaurs and the most well-known ceratopsid.
