Chirostenotes Limbs
''Chirostenotes'' ( ; named from Ancient Greek, Greek 'narrow-handed') is a genus of oviraptorosaurian dinosaur from the late Cretaceous (about 76.5–75 million years ago) of Alberta, Canada. The type species is ''Chirostenotes pergracilis''. History of discovery ''Chirostenotes'' has a confusing history of discovery and naming. The first fossils of ''Chirostenotes'', a pair of hands, were in 1914 found by George Fryer Sternberg near Little Sandhill Creek in the Campanian Dinosaur Park Formation of Canada, which has yielded the most dinosaurs of any Canadian formation. The specimens were studied by Lawrence Morris Lambe who, however, died before being able to formally name them. In 1924, Charles Whitney Gilmore adopted the name he found in Lambe's notes and described and named the type species ''Chirostenotes pergracilis''. The generic name is derived from Greek ''cheir'', "hand", and ''stenotes'', "narrowness". The specific name (zoology), specific name means "throughout", ''p ...

Late Cretaceous
The Late Cretaceous (100.5–66 Ma) is the more recent of two epochs into which the Cretaceous Period is divided in the geologic time scale. Rock strata from this epoch form the Upper Cretaceous Series. The Cretaceous is named after ''creta'', the Latin word for the white limestone known as chalk. The chalk of northern France and the white cliffs of south-eastern England date from the Cretaceous Period. Climate During the Late Cretaceous, the climate was warmer than present, although throughout the period a cooling trend is evident. The tropics became restricted to equatorial regions and northern latitudes experienced markedly more seasonal climatic conditions. Geography Due to plate tectonics, the Americas were gradually moving westward, causing the Atlantic Ocean to expand. The Western Interior Seaway divided North America into eastern and western halves; Appalachia and Laramidia. India maintained a northward course towards Asia. In the Southern Hemisphere, Aus ...

Charles Whitney Gilmore
Charles Whitney Gilmore (March 11, 1874 – September 27, 1945) was an American paleontologist who gained renown in the early 20th century for his work on vertebrate fossils during his career at the United States National Museum (now the National Museum of Natural History). Gilmore named many dinosaurs in North America and Mongolia, including the Cretaceous sauropod ''Alamosaurus'', ''Alectrosaurus'', '' Archaeornithomimus'', ''Bactrosaurus'', '' Brachyceratops'', ''Chirostenotes'', '' Mongolosaurus'', '' Parrosaurus'', ''Pinacosaurus'', ''Styracosaurus ovatus'' (now '' Rubeosaurus'') and ''Thescelosaurus''. Career Gilmore was working as a paleontologist for the Carnegie Museum of Natural History in 1901 when he found the skeleton of a young sauropod, which was classified the following year as an ''Apatosaurus''. In 1903 Gilmore was hired by the United States National Museum (now the National Museum of Natural History), part of the Smithsonian Institution. His first assign ...

Alexander Wetmore
Frank Alexander Wetmore (June 18, 1886 – December 7, 1978) was an American ornithologist and avian paleontologist. He was the sixth Secretary of the Smithsonian Institution. He was also an elected member of both the American Philosophical Society and the United States National Academy of Sciences. Early life and education The son of a physician, Frank Alexander Wetmore was born in North Freedom, Wisconsin.

Bird
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Steveville
Steveville is a ghost town in southeastern Alberta, Canada near Brooks. In 1910, the community had a general store. Named after Steve Hall, a local homesteader, the community never attracted a large population. The Hall family operated a number of businesses in Steveville, including a ferry across the Red Deer River, a boarding house, and the general store and post office. Steveville lies near the northwest boundary of Dinosaur Provincial Park at the edge of the badlands within the Red Deer River valley, and it is most notable as the discovery location for many specimens of dinosaurs. These come from the Dinosaur Park Formation of Late Cretaceous (Campanian) age and include remains of ''Styracosaurus'', ''Daspletosaurus'', ''Corythosaurus'', ''Struthiomimus'', and others. Amateur palaeontologist Irene Vanderloh (1917–2009) was born in Steveville. In 1974, she discovered the holotype of the theropod dinosaur ''Saurornitholestes ''Saurornitholestes'' ("lizard-bird thief") is ...

Raymond Sternberg
Raymond is a male given name of Germanic origin. It was borrowed into English from French (older French spellings were Reimund and Raimund, whereas the modern English and French spellings are identical). It originated as the Germanic ᚱᚨᚷᛁᚾᛗᚢᚾᛞ (''Raginmund'') or ᚱᛖᚷᛁᚾᛗᚢᚾᛞ (''Reginmund''). ''Ragin'' ( Gothic) and ''regin'' (Old German) meant "counsel". The Old High German ''mund'' originally meant "hand", but came to mean "protection". This etymology suggests that the name originated in the Early Middle Ages, possibly from Latin. Alternatively, the name can also be derived from Germanic Hraidmund, the first element being ''Hraid'', possibly meaning "fame" (compare ''Hrod'', found in names such as Robert, Roderick, Rudolph, Roland, Rodney and Roger) and ''mund'' meaning "protector". Despite the German and French origins of the English name, some of its early uses in English documents appear in Latinized form. As a surname, its first recorded ...

Ornithomimid
Ornithomimidae (meaning "bird-mimics") is an extinct family of theropod dinosaurs which bore a superficial resemblance to modern ostriches. Ornithomimids were fast, omnivorous or herbivorous dinosaurs known mainly from the Late Cretaceous Period of Laurasia (now Asia and North America), though they have also been reported from the Lower Cretaceous Wonthaggi Formation of Australia. Description The skulls of ornithomimids were small, with large eyes, above relatively long and slender necks. All had toothless beaks. The fore limbs ('arms') were long and slender and bore powerful claws. The hind limbs were long and powerful, with a long foot and short, strong toes terminating in hooflike claws. Ornithomimids were probably among the fastest of all dinosaurs.Holtz, Thomas R. Jr. (2012) ''Dinosaurs: The Most Complete, Up-to-Date Encyclopedia for Dinosaur Lovers of All Ages,'Winter 2011 Appendix./ref> Like many other coelurosaurs, the ornithomimid hide was feathered rather than scaly. ...

Charles Mortram Sternberg
Charles Mortram Sternberg (18 September 1885 – 8 September 1981) was an American-Canadian fossil collector and paleontologist, son of Charles Hazelius Sternberg. Late in his career, he collected and described '' Pachyrhinosaurus'', ''Brachylophosaurus'', ''Parksosaurus'' and '' Edmontonia''. A contemporary author wrote, "No published study of Canadian dinosaurs is possible today without citing one or another of Sternberg's papers." Early life Charles Mortram Sternberg was born in Lawrence, Kansas, from a family of famous American fossil collectors. Sternberg's highest level of education was a Kansas high school degree. Career Sternberg moved with his father and two brothers, Levi and George, to Ottawa, Ontario, Canada in 1912. The four began working in Alberta collecting dinosaurs on behalf of the Geological Survey of Canada. This work was in competition with the American Museum of Natural History (New York) who were collecting many fossil skeletons and shipping them out of ...

Dromaeosaurid
Dromaeosauridae () is a family (biology), family of feathered coelurosaurian Theropoda, theropod dinosaurs. They were generally small to medium-sized feathered carnivores that flourished in the Cretaceous period (geology), Period. The name Dromaeosauridae means 'running lizards', from Ancient Greek, Greek ('), meaning 'running at full speed', 'swift', and ('), meaning 'lizard'. In informal usage, they are often called raptors (after ''Velociraptor''), a term popularized by the film ''Jurassic Park (film), Jurassic Park''; several Genus, genera include the term "raptor" directly in their name, and popular culture has come to emphasize their bird-like appearance and speculated bird-like behavior. Dromaeosaurid fossils have been found across the globe in North America, Europe, Africa, Asia and South America, with some fossils giving credence to the possibility that they inhabited Australia as well. The earliest body fossils are known from the Early Cretaceous (145–140 million y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richardoestesia
''Richardoestesia'' is a morphogenus of theropod dinosaur teeth, originally described from the Late Cretaceous of what is now Canada, the United States and Kazakhstan. It currently contains two species, ''R. gilmorei'' and ''R. isosceles'', and a possible third, '' R. asiatica''. It has been used as a morphotaxon to describe other theropod teeth widely displaced in time and space from the type species. If all teeth assigned to the genus are truly reflective of the animals biology and taxonomic state (as some teeth go as far back as the Late Jurassic), it would have been one of the longest lasting dinosaur genera, perhaps also being the most widely distributed. History The jaws were found in 1917 by Charles Hazelius Sternberg and sons in the Dinosaur Provincial Park in Alberta at the Little Sandhill Creek site. In 1924 Charles Whitney Gilmore named ''Chirostenotes pergracilis'' and referred the jaws to this species. In the 1980s it became clear that ''Chirostenotes'' was ...
