Zuniceratops
''Zuniceratops'' ('Zuni-horned face') was a ceratopsian dinosaur from the mid Turonian of the Late Cretaceous Period of what is now New Mexico, United States. It lived about 10 million years earlier than the more familiar horned Ceratopsidae and provides an important window on their ancestry''.'' Description ''Zuniceratops'' measured about long. It probably weighed about , making it substantially smaller than most ceratopsids. The skull bears a well-developed pair of brow horns, similar to those of chasmosaurs and primitive centrosaurs, but the nose horn is absent. The brow horns are thought to have grown much larger with age. The snout is long and low, like that of chasmosaurines. The frill was a thin, broad, shield-like structure. It bore a pair of large holes but lacked epoccipital bones, as in ''Protoceratops''. Overall, the anatomy is much more primitive than that of the ceratopsids, but more advanced than in protoceratopsids. Discovery and species ''Zuniceratops'' w ...

Ceratopsia
Ceratopsia or Ceratopia ( or ; Greek: "horned faces") is a group of herbivorous, beaked dinosaurs that thrived in what are now North America, Europe, and Asia, during the Cretaceous 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.

Protoceratops
''Protoceratops'' (; ) is a genus of small protoceratopsid dinosaurs that lived in Asia during the Late Cretaceous, around 75 to 71 million years ago. The genus ''Protoceratops'' includes two species: ''P. andrewsi'' and the larger ''P. hellenikorhinus''. The former was described in 1923 with fossils from the Mongolian Djadokhta Formation, and the latter in 2001 with fossils from the Chinese Bayan Mandahu Formation. ''Protoceratops'' was initially believed to be an ancestor of ankylosaurians and larger ceratopsians, such as ''Triceratops'' and relatives, until the discoveries of other protoceratopsids. Populations of ''P. andrewsi'' may have evolved into ''Bagaceratops'' through anagenesis. ''Protoceratops'' were small ceratopsians, about long and in body mass. While adults were largely quadrupedal, juveniles had the capacity to walk around bipedally if necessary. They were characterized by a proportionally large skull, short and stiff neck, and neck frill. The frill was likel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moreno Hill Formation
The Moreno Hill Formation is a geological formation in western New Mexico whose strata were deposited in the Late Cretaceous. 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)." In: Weishampel, David B.; Dodson, Peter; and Osmólska, Halszka (eds.): The Dinosauria, 2nd, Berkeley: University of California Press. Pp. 574-588. . Description The formation is a nonmarine coal-bearing formation composed mostly of sandstone and shale with minor siltstone. The shales are brownish gray in color, and the sandstones are discontinuous beds of very pale orange to light brown poorly sorted grains that usually show steep crossbedding. The sandstones are interpreted as channel or splay deposits in a fluvial environment. The shales include thin lenses of bituminous coal, including tonsteins (distinctive thin ash beds). The total maximum thickness is . It overlies the Atar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Kirkland (paleontologist)
James Ian Kirkland (born August 24, 1954) is an American paleontologist and geologist. He has worked with dinosaur remains from the south west United States of America and Mexico and has been responsible for discovering new and important genera. He named (or worked with others in naming) ''Animantarx'', '' Cedarpelta'', '' Eohadrosaurus'' ('' nomen nudum'', now named ''Eolambia''), '' Jeyawati'', '' Gastonia'', ''Mymoorapelta'', '' Nedcolbertia'', ''Utahraptor'', ''Zuniceratops'', ''Europelta'' and ''Diabloceratops''. At the same site where he found '' Gastonia'' and ''Utahraptor'', Kirkland has also excavated fossils of the therizinosaur ''Falcarius''.Kirkland, Zanno, Sampson, Clark & DeBlieux 2005, pp. 84-87.

Timeline Of Ceratopsian Research
This timeline of ceratopsian research is a chronological listing of events in the history of paleontology focused on the ceratopsians, a group of herbivorous marginocephalian dinosaurs that evolved parrot-like beaks, bony frills, and, later, spectacular horns. The first scientifically documented ceratopsian fossils were described by Edward Drinker Cope starting in the 1870s; however, the remains were poorly preserved and their true nature was not recognized. Over the next several decades, Cope named several such genera and species. Cope's hated rival, Othniel Charles Marsh, also described ceratopsian remains. In 1887, Marsh mistook a ''Triceratops'' horn for one belonging to a new species of prehistoric ''Bison''. Marsh also named the eponymous genus ''Ceratops'' in 1888. The next year, he named the most famous ceratopsian, ''Triceratops horridus''. It was the discovery of ''Triceratops'' that illuminated the ceratopsian body plan, and he formally named the Ceratopsia in 1890. ...

Nothronychus
''Nothronychus'' (meaning "slothful claw") is a genus of therizinosaurid theropod dinosaurs that lived in North America during the Late Cretaceous period. The type species, ''Nothronychus mckinleyi'', was described by James Kirkland and Douglas G. Wolfe in 2001. It was recovered near New Mexico's border with Arizona, in an area known as the Zuni Basin, from rocks assigned to the Moreno Hill Formation, dating to the late Cretaceous period (mid-Turonian stage), around 91 million years ago. A second specimen, described in 2009 as a second species, ''Nothronychus graffami'', was found in the Tropic Shale of Utah, dating to the early Turonian, between one million and a half million years older than ''N. mckinleyi''. ''Nothronychus'' were bulky herbivorous theropods with wide, sloth-like hip (resembling that of the non-related ornithischians), four-toed feet with all four toes facing forward, elongated necks and prominent arms with sharp claws. Both species were similar in dimensions, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
