Dromiceiomimus
''Dromiceiomimus'' is a genus of ornithomimid theropod from the Late Cretaceous (early Maastrichtian) of Alberta, Canada. The type species, ''D. brevitertius'', is considered a synonym of ''Ornithomimus edmontonicus'' by some authors, while others consider it a distinct and valid taxon. Taxonomy The type species, ''D. brevitertius'' was originally described as a species of ''Struthiomimus'' by William Parks in 1926 on the basis of a partial postcranium, ROM 797, from the Horseshoe Canyon Formation of Alberta, Canada. In his review of Canadian ornithomimids, Dale Russell made ''S. brevitertius'' the type species of a new genus, ''Dromiceiomimus'', meaning "emu mimic" from the old generic name for the emu, ''Dromiceius''. Russell also synonymized ''Struthiomimus ingens'' with ''Dromiceimimus brevitertius''. He renamed ''Ornithomimus samueli'' into a second ''Dromiceiomimus'' species: ''Dromiceiomimus samueli''. ''Dromiceiomimus'' was distinguished from ''Ornithomimus edmontonicu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ornithomimus Edmontonicus
''Ornithomimus'' (; "bird mimic") is a genus of ornithomimid dinosaurs from the Late Cretaceous Period of what is now North America. ''Ornithomimus'' was a swift bipedal theropod which fossil evidence indicates was covered in feathers, equipped with a small toothless beak that may indicate an omnivorous diet. It is usually classified into two species: the type species, ''Ornithomimus velox'', and a referred species, ''Ornithomimus edmontonicus''. ''O. velox'' was named in 1890 by Othniel Charles Marsh on the basis of a foot and partial hand from the late Maastrichtian-age Denver Formation of Colorado, United States. Another seventeen species have been named since, though most of them have subsequently been assigned to new genera or shown to be not directly related to ''Ornithomimus velox''. The best material of species still considered part of the genus has been found in Alberta, Canada, representing the species ''O. edmontonicus'', known from several skeletons from the early Maas ...

Struthiomimus
''Struthiomimus'' (meaning "ostrich mimic", from the Ancient Greek, Greek στρούθειος/''stroutheios'' meaning "of the ostrich" and μῖμος/''mimos'' meaning "mimic" or "imitator") is a genus of Ornithomimidae, ornithomimid dinosaurs from the late Cretaceous of North America. Ornithomimids were long-legged, bipedal, ostrich-like dinosaurs with toothless beaks. The type species, ''Struthiomimus altus'', is one of the more common small dinosaurs found in Dinosaur Provincial Park; its abundance suggests that these animals were herbivores or omnivores rather than pure carnivores. History of discovery In 1901, Lawrence Lambe found some incomplete remains, holotype CMN 930, and named them ''Ornithomimus altus'', placing them in the same genus as material earlier described by Othniel Charles Marsh in 1890. The specific name (zoology), specific name ''altus'' is from Latin, meaning "lofty" or "noble". However, in 1914, a nearly complete skeleton (AMNH 5339) was discovered by ...

Ornithomimid
Ornithomimidae (meaning "bird-mimics") is a 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.

Dale Russell
Dale Alan Russell (27 December 1937 – 21 December 2019) was an American-Canadian geologist and palaeontologist. Throughout his career Russell worked as the Curator of Fossil Vertebrates at the Canadian Museum of Nature, Research Professor at the Department of Marine Earth and Atmospheric Sciences (MEAS) at North Carolina State University, and Senior Paleontologist at the North Carolina Museum of Natural Sciences. Dinosaurs he has described include '' Daspletosaurus'' and ''Dromiceiomimus'', and he was amongst the first paleontologists to consider an extraterrestrial cause (supernova, comet, asteroid) for the Cretaceous–Paleogene extinction event. Russell also helped lead the China-Canada Dinosaur Project from 1986 to 1991. In 1982, Russell created the "dinosauroid" thought experiment, which speculated an evolutionary path for ''Troodon'' if it had not gone extinct in the Cretaceous–Paleogene extinction event The Cretaceous–Paleogene (K–Pg) extinction event (als ...

William Parks (paleontologist)
William Arthur Parks (11 December 1868 – 3 October 1936) was a Canadian geologist and paleontologist, following in the tradition of Lawrence Lambe. Parks was born in Hamilton, Ontario. After graduating with a Bachelor of Arts in 1892, Parks joined the University of Toronto's staff, where he taught geology, paleontology, and mineralogy. He went on to earn a PhD in 1900. He wrote 80 scientific papers in his lifetime. Parks died in Toronto, Ontario, in 1936.

Paleontology In Alberta
Paleontology (), also spelled palaeontology or palæontology, is the scientific study of life that existed prior to, and sometimes including, the start of the Holocene epoch (roughly 11,700 years before present). It includes the study of fossils to classify organisms and study their interactions with each other and their environments (their paleoecology). Paleontological observations have been documented as far back as the 5th century BC. The science became established in the 18th century as a result of Georges Cuvier's work on comparative anatomy, and developed rapidly in the 19th century. The term itself originates from Greek (, "old, ancient"), (, (gen. ), "being, creature"), and (, "speech, thought, study"). Paleontology lies on the border between biology and geology, but differs from archaeology in that it excludes the study of anatomically modern humans. It now uses techniques drawn from a wide range of sciences, including biochemistry, mathematics, and engineering. Us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maastrichtian Life
The Maastrichtian () is, in the ICS geologic timescale, the latest age (uppermost stage) of the Late Cretaceous Epoch or Upper Cretaceous Series, the Cretaceous Period or System, and of the Mesozoic Era or Erathem. It spanned the interval from . The Maastrichtian was preceded by the Campanian and succeeded by the Danian (part of the Paleogene and Paleocene). The Cretaceous–Paleogene extinction event (formerly known as the Cretaceous–Tertiary extinction event) occurred at the end of this age. In this mass extinction, many commonly recognized groups such as non-avian dinosaurs, plesiosaurs and mosasaurs, as well as many other lesser-known groups, died out. The cause of the extinction is most commonly linked to an asteroid about wide colliding with Earth, ending the Cretaceous. Stratigraphic definitions Definition The Maastrichtian was introduced into scientific literature by Belgian geologist André Hubert Dumont in 1849, after studying rock strata of the Chalk Gr ...

Fossil Taxa Described In 1926
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the abso ...
