Nedcolbertia
''Nedcolbertia'' is a genus of theropod dinosaur from the Early Cretaceous Period of North America. Discovery and naming Three skeletons of a theropod were discovered in 1993 by Christopher Whittle near Cisco in the basal Yellow Cat Member of the Cedar Mountain Formation of Utah, dating to the Valanginian. These were subsequently studied and reported in 1995 by Kirkland, Britt, Madsen and Burge.J. I. Kirkland, C. H. Whittle, B. B. Britt, S. Madsen and D. Burge. A Small Theropod from the Basal Cedar Mountain Formation (Lower Cretaceous, Barremian) of Eastern Utah. Journal of Vertebrate Paleontology. 15(3), 39A (1995). Though in 1996 it had been announced that the taxon would be named "Nedcolbertia whittlei", in 1998 it was actually described and named by Kirkland, Whittle, Britt, Madsen and Burge as the type species ''Nedcolbertia justinhofmanni''. The generic name honours the American palaeontologist Edwin Harris Colbert, known as "Ned" to his friends. The specific name honou ...

Ornithomimosaurs
Ornithomimosauria ("bird-mimic lizards") are theropod dinosaurs which bore a superficial resemblance to the modern-day ostrich. They were fast, omnivorous or herbivorous dinosaurs from the Cretaceous Period of Laurasia (now Asia, Europe and North America), as well as Africa and possibly Australia. The group first appeared in the Early Cretaceous and persisted until the Late Cretaceous. Primitive members of the group include '' Nqwebasaurus'', ''Pelecanimimus'', '' Shenzhousaurus'', '' Hexing'' and '' Deinocheirus'', the arms of which reached 2.4 m (8 feet) in length. More advanced species, members of the family Ornithomimidae, include '' Gallimimus'', '' Struthiomimus'', and '' Ornithomimus''. Some paleontologists, like Paul Sereno, consider the enigmatic alvarezsaurids to be close relatives of the ornithomimosaurs and place them together in the superfamily Ornithomimoidea (see classification below). Description The skulls of ornithomimosaurs were small, with large e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arundel Formation
The Arundel Formation, also known as the Arundel Clay, is a clay-rich sedimentary rock formation, within the Potomac Group, found in Maryland of the United States of America. It is of Aptian age (Lower Cretaceous). This rock unit had been economically important as a source of iron ore, but is now more notable for its dinosaur fossils. It consists of clay lenses within depressions in the upper part of the Patuxent Formation that may represent oxbow swamp facies. It is named for Anne Arundel County, Maryland. Vertebrate paleofauna Dinosaurs Dinosaurs present include cf. ''Acrocanthosaurus'', the possible ornithischian '' Magulodon'', the poorly known theropods ''"Allosaurus" medius'', '' "Creosaurus" potens'', and ''"Coelurus" gracilis'', the ornithomimosaurian ''"Dryosaurus" grandis'', as well as another indeterminate ornithomimosaurian (though it most likely is '' Nedcolbertia''), the sauropod ''Astrodon'', the nodosaurid ''Priconodon'', a possible basal ceratopsian, an ...

Cedar Mountain Formation
The Cedar Mountain Formation is the name given to a distinctive sedimentary geologic formation in eastern Utah, spanning most of the early and mid- Cretaceous. The formation was named for Cedar Mountain in northern Emery County, Utah, where William Lee Stokes first studied the exposures in 1944. Geology The formation occurs between the underlying Morrison Formation and overlying Naturita Formation (sometimes formerly called the Dakota Formation). It is composed of non-marine sediments, that is, sediments deposited in rivers, lakes and on flood plains. Based on various fossils and radiometric dates, the Cedar Mountain Formation was deposited during the last half of the Early Cretaceous Epoch, about 127 - 98 million years ago (mya). It has lithography similar to the Burro Canyon Formation in the region. Dinosaur fossils occur throughout the formation, but their study has only occurred since the early 1990s. The dinosaurs in the lower part of the formation differ from those ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coelurosauria
Coelurosauria (; from Greek, meaning "hollow tailed lizards") is the clade containing all theropod dinosaurs more closely related to birds than to carnosaurs. Coelurosauria is a subgroup of theropod dinosaurs that includes compsognathids, tyrannosaurs, ornithomimosaurs, and maniraptorans; Maniraptora includes birds, the only known dinosaur group alive today. Most feathered dinosaurs discovered so far have been coelurosaurs. Philip J. Currie had considered it likely and probable that all coelurosaurs were feathered. However, several skin impressions found for some members of this group show pebbly, scaly skin, indicating that feathers did not completely replace scales in all taxa. In the past, Coelurosauria was used to refer to all small theropods, but this classification has since been abolished. Anatomy Bodyplan The studying of anatomical traits in coelurosaurs indicates that the last common ancestor had evolved the ability to eat and digest plant matter, adapting to an ...

Tetanurae
Tetanurae (/ˌtɛtəˈnjuːriː/ or "stiff tails") is a clade that includes most theropod dinosaurs, including megalosauroids, allosauroids, tyrannosauroids, ornithomimosaurs, compsognathids and maniraptorans (including birds). Tetanurans are defined as all theropods more closely related to modern birds than to ''Ceratosaurus'' and contain the majority of predatory dinosaur diversity. Tetanurae likely diverged from its sister group, Ceratosauria, during the late Triassic. Tetanurae first appeared in the fossil record by the Early Jurassic about 190 mya and by the Middle Jurassic had become globally distributed. The group was named by Jacques Gauthier in 1986 and originally had two main subgroups: Carnosauria and Coelurosauria, the clade containing birds and related dinosaurs such as compsognathids, tyrannosaurids, ornithomimosaurs, and maniraptorans. The original Carnosauria was a polyphyletic group including any large carnivorous theropod. Many of Gauthier's carnosaurs, suc ...

College Of Eastern Utah Prehistoric Museum
The Prehistoric Museum, USU-Eastern, formerly known as the College of Eastern Utah Prehistoric Museum, is a museum accredited by the American Alliance of Museums located in Price, Utah. The museum seeks to promote public understanding of prehistory through interpretive exhibits, educational programs, collections, and research. The museum is located near many paleontological and archaeological sites in a region known as Castle Country, notably in the San Rafael Swell and nearby canyons throughout the Book Cliffs area such as Nine Mile Canyon and Range Creek Canyon. History The Prehistoric Museum was established in 1961 as a cooperative effort by the former College of Eastern Utah and the community of Price. On May 8, 1961, the Board of Regents established the museum. At that time, funding for the museum was supplied by the geology department at the college. The museum officially opened to the public on June 3, 1961, on the second floor of the Price Municipal Building in a sma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harpymimus
''Harpymimus'' is a basal ornithomimosaurian theropod dinosaur from the Early Cretaceous Period of what is now Mongolia. Unlike later, more derived ornithomimosaurs, ''Harpymimus'' still possessed teeth, although they appear to have been restricted to the dentary of the lower jaw. Discovery and naming In 1981, a Soviet-Mongolian expedition uncovered a theropod skeleton in the Gobi Desert. In 1984 this was named and shortly described by Rinchen Barsbold and Altangerel Perle as the type and only species of the new genus ''Harpymimus'': ''Harpymimus okladnikovi''. The generic name ''Harpymimus'' is a reference to the fearsome Harpy of Greek mythology and derived from Greek ἅρπυια (''harpyia''), "Harpy", and μῖμος (''mimos''), "mimic". The specific name honours the late Soviet archeologist Alexey Pavlovich Okladnikov. The holotype specimen IGM 100/29 (Mongolian Academy of Sciences, Ulan Bator, Mongolia) consists of an almost complete and articulated but compre ...

Nqwebasaurus
''Nqwebasaurus'' (; anglicized as or ) is a basal coelurosaur and is the basal-most member of the coelurosaurian clade Ornithomimosauria from the Early Cretaceous of South Africa. The name ''Nqwebasaurus'' is derived from the Xhosa word "Nqweba" which is the local name for the Kirkwood district, and "thwazi" is ancient Xhosa for "fast runner". Currently it is the oldest coelurosaur in Africa and shows that basal coelurosaurian dinosaurs inhabited Gondwana 50 million years earlier than previously thought. The type specimen of ''Nqwebasaurus'' was discovered by William J. de Klerk who is affiliated with the Albany Museum in Grahamstown. It is the only fossil of its species found to date and was found in the Kirkwood Formation of the Uitenhage Group. ''Nqwebasaurus'' has the unofficial nickname "Kirky", due to being found in the Kirkwood. History of discovery ''Nqwebasaurus'' was first discovered by William J. de Klerk and Callum Ross in July 1996 during a joint expedition le ...
