Diabloceratops
''Diabloceratops'' ( ) is an extinct genus of centrosaurine ceratopsian dinosaur that lived approximately 81.4-81 million years ago during the latter part of the Cretaceous Period in what is now Utah, in the United States. ''Diabloceratops'' was a medium-sized, moderately built, ground-dwelling, quadrupedal herbivore, that could grow up to an estimated in length and in body mass. At the time of its discovery, it was the oldest-known ceratopsid, and first centrosaurine known from latitudes south of the U.S. state of Montana. The generic name ''Diabloceratops'' means "devil-horned face," coming from ''Diablo'', Spanish for "devil," and ''ceratops'', Latinized Greek for "horned face." The specific name honors Jeffrey Eaton, a paleontologist at Weber State University and long time friend of the lead author Jim Kirkland. Eaton had a big role in establishing the Grand Staircase-Escalante National Monument where the specimen was found. The type species, ''Diabloceratops eatoni'', was ...

Wahweap Formation
The Wahweap Formation of the Grand Staircase–Escalante National Monument is a geological Formation (geology), formation in southern Utah and northern Arizona, around the Lake Powell region, whose strata date back to the Late Cretaceous (Campanian stage). Dinosaur remains are among the fossils that have been recovered from the formation.Weishampel, David B; et al. (2004). "Dinosaur distribution (Late Cretaceous, North America)."

Machairoceratops
''Machairoceratops'' (meaning "bent sword horned face"), previously known as the "Wahweap centrosaurine B", is an extinct genus of centrosaurine ceratopsian dinosaur known from the Late Cretaceous Wahweap Formation (late Campanian stage) of Grand Staircase–Escalante National Monument, southern Utah, United States. Discovery It contains a single species, ''M. cronusi'', first described and named in 2016 in paleontology, 2016 by Eric K. Lund, Patrick M. O’Connor, Mark A. Loewen, and Zubair A. Jinnah. The name of a biological genus, generic name is derived from Greek language, Greek ''machairis'', meaning "bent sword", in reference to its unique frill ornamentation showing two forward curving horns on the frill's uppermost part, and Latinized Greek ''ceratops'', meaning "horned-face", which is a common suffix for ceratopsian genera names. The specific name (zoology), specific name ''cronusi'' refers to Cronus, a Greek god who deposed his father Uranus (mythology), Uranus by ca ...

Centrosaurine
Centrosaurinae (from the Greek, meaning "pointed lizards") is a subfamily of ceratopsid, a group of large quadrupedal ornithischian dinosaur. Centrosaurine fossil remains are known primarily from the northern region of Laramidia (modern day Alberta, Montana, and Alaska) but isolated taxa have been found in China and Utah as well. Defining features of centrosaurines include a large nasal horn, short supratemporal horns, and an ornamented frill projecting from the back of the skull. With the exception of ''Centrosaurus apertus'', all adult centrosaurines have spike-like ornaments midway up the skull. Morphometric analysis shows that centrosaurines differ from other ceratopsian groups in skull, snout, and frill shapes. There is evidence to suggest that male centrosaurines had an extended period of adolescence, and sexual ornamentation did not appear until adulthood. Centrosaurinae was named by paleontologist Lawrence Lambe in 1915, with ''Centrosaurus'' as the type genus. It is defi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yehuecauhceratops
''Yehuecauhceratops'' (meaning "ancient horned face") is a genus of horned centrosaurinae, centrosaurine ceratopsidae, ceratopsid dinosaur from the Late Cretaceous of Coahuila, Mexico. It contains a single species, ''Y. mudei'', described from two partial specimens by Rivera-Sylva ''et al.'' in 2016 and formally named by Rivera-Sylva ''et al.'' in 2017. It was a small centrosaurine with a body length of , making it smaller than ''Agujaceratops'' and ''Coahuilaceratops'', the other two ceratopsids in its environment; the three may have been ecologically segregated. A ridge bearing a single roughened projection near the bottom of the squamosal bone, which probably supported a small horn, allows ''Yehuecauhceratops'' to be distinguished from other centrosaurines. Its affinities to nasutoceratopsin centrosaurines, such as ''Avaceratops'' and ''Nasutoceratops'', are supported by various morphology (biology), morphological similarities to the former.

Ceratopsian
Ceratopsia or Ceratopia ( or ; Greek: "horned faces") is a group of herbivorous, beaked dinosaurs that thrived in what are now North America, Asia and Europe, during the Cretaceous Period, although ancestral forms lived earlier, in the Late Jurassic of Asia. 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 fossil remains have no disti ...

Natural History Museum Of Utah
The Natural History Museum of Utah is a museum located in Salt Lake City, Utah, United States. The museum shows exhibits of natural history subjects, with an emphasis on Utah and the Intermountain West. The mission of the museum is to illuminate the natural world and the place of humans within it. A new building, named the Rio Tinto Center, opened in November 2011. The museum is part of the University of Utah and is located in the university's Research Park. History The museum was conceived in 1959, when the University of Utah faculty committee decided to consolidate natural history collections from around its campus. The museum was established as the Utah Museum of Natural History on the University of Utah campus in 1963 by the Utah State Legislature. In 1969, the museum opened in the former George Thomas Library and included specimens from the Deseret Museum, as well as from the Charles Nettleton Strevell Museum that was located in the old Lafayette School on South Templ ...

Menefeeceratops
''Menefeeceratops'' (meaning "Menefee Formation horned face") is a genus of ceratopsid dinosaur from the Menefee Formation in New Mexico, United States. It is potentially the oldest known member of the ceratopsids, as well as the centrosaurine subfamily, related to animals including '' Yehuecauhceratops'' and '' Crittendenceratops''. The type and only species is ''Menefeeceratops sealeyi'', known from a partial, non-articulated skeleton. Discovery and naming The holotype, NMMNH P-25052, of ''Menefeeceratops'' was discovered by Paul Sealey in 1996 and later mentioned in a paper in 1997,. but was not given a name until it was revisited in 2021 by Sebastian Dalman, Peter Dodson, and colleagues. The holotype was collected at the NMMNH locality 3033 in Sandoval County, New Mexico, USA, whose rocks came from the early Campanian rocks of the Allison Member of the Menefee Formation. The holotype was later collected by the New Mexico Museum of Natural History with permission of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stage (stratigraphy)
In chronostratigraphy, a stage is a succession of rock strata laid down in a single age on the geologic timescale, which usually represents millions of years of deposition. A given stage of rock and the corresponding age of time will by convention have the same name, and the same boundaries. Rock series are divided into stages, just as geological epochs are divided into ages. Stages are divided into smaller stratigraphic units called chronozones or substages, and added together into superstages. The term faunal stage is sometimes used, referring to the fact that the same fauna (animals) are found throughout the layer (by definition). Definition Stages are primarily defined by a consistent set of fossils ( biostratigraphy) or a consistent magnetic polarity (see paleomagnetism) in the rock. Usually one or more index fossils that are common, found worldwide, easily recognized, and limited to a single, or at most a few, stages are used to define the stage's bottom. Thus, f ...
