1912 In Paleontology
Expeditions, field work, and fossil discoveries * William Edmund Cutler first began collecting fossils, choosing the mouth of Kneehills Creek in Alberta as a prospecting site. According to paleontologist Darren Tanke, Cutler was motivated by "commercial gain".D. H. Tanke. 2010. Lost in plain sight: rediscovery of William E. Cutler's missing Eoceratops. In M. J. Ryan, B. J.

Lawrence Lambe
Lawrence Morris Lambe (August 27, 1863 – March 12, 1919) was a Canadian geologist, palaeontologist, and ecologist from the Geological Survey of Canada (GSC). His published work, describing the diverse and plentiful dinosaur discoveries from the fossil beds in Alberta, did much to bring dinosaurs into the public eye and helped usher in the ''Golden Age of Dinosaurs'' in the province. During this period, between the 1880s and World War I, dinosaur hunters from all over the world converged on Alberta. ''Lambeosaurus'', a well-known hadrosaur, was named after him as a tribute, in 1923. In addition to paleontology, Lambe discovered a number of invertebrate species ranging from Canada to the Pacific Northwest. Lambe's contemporary discoveries were published in works such as ''Sponges From the Atlantic Coast of Canada'' and ''Catalogue of the recent marine sponges of Canada and Alaska''. Early life and education Lambe was born in Montreal on August 27, 1863. Lambe studied at the Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emydochampsa
''Endothiodon'' (/ɛndoʊθiːoʊdɔːn/ "inner tooth" from Greek endothi (ἔνδοθῐ), "within", and odon (ὀδών), "tooth", most likely named for the characteristic of the teeth being placed internally to the maxillaBoos A. S., Schultz C. L., Vega C. S., Aumond J. J. "On the presence of the Late Permian dicynodont ''Endothiodon'' in Brazil" Palaeontology 56:4, 837-848 (2013)) is an extinct genus of large dicynodont from the Late Permian. Like other dicynodonts, ''Endothiodon'' was an herbivore, but it lacked the two tusks that characterized most other dicynodonts. The anterior portion of the upper and lower jaw are curved upward, creating a distinct beak that is thought to have allowed them to be specialized grazers.Latimer E. M., Gow C. E., Rubidge B. S.

The Lost World (Conan Doyle Novel)
''The Lost World'' is a science fiction novel by British writer Sir Arthur Conan Doyle, published by Hodder & Stoughton in 1912, concerning an expedition to a plateau in the Amazon basin of South America where prehistoric animals still survive. It was originally published serially in the '' Strand Magazine'' and illustrated by New Zealand–born artist Harry Rountree during the months of April–November 1912. The character of Professor Challenger was introduced in this book. The novel also describes a war between indigenous people and a vicious tribe of ape-like creatures. Plot summary Edward Malone, a young reporter for the ''Daily Gazette'', asks his editor for a dangerous assignment to impress the woman he loves, Gladys, who wishes for a great man capable of brave deeds and actions. His task is to approach the notorious Professor Challenger, who dislikes the popular press intensely and physically assaults intrusive journalists. The subject is to be his recent South A ...

Hadrosaurid
Hadrosaurids (), or duck-billed dinosaurs, are members of the ornithischian family Hadrosauridae. This group is known as the duck-billed dinosaurs for the flat duck-bill appearance of the bones in their snouts. The ornithopod family, which includes genera such as ''Edmontosaurus'' and ''Parasaurolophus'', was a common group of herbivores during the Late Cretaceous Period. Hadrosaurids are descendants of the Upper Jurassic/Lower Cretaceous iguanodontian dinosaurs and had a similar body layout. Hadrosaurs were among the most dominant herbivores during the Late Cretaceous in Asia and North America, and during the close of the Cretaceous several lineages dispersed into Europe, Africa, South America and Antarctica. Like other ornithischians, hadrosaurids had a predentary bone and a pubic bone which was positioned backwards in the pelvis. Unlike more primitive iguanodonts, the teeth of hadrosaurids are stacked into complex structures known as dental batteries, which acted as effe ...

Barnum Brown
Barnum Brown (February 12, 1873 – February 5, 1963), commonly referred to as Mr. Bones, was an American paleontologist. Named after the circus showman P. T. Barnum, he discovered the first documented remains of ''Tyrannosaurus'' during a career that made him one of the most famous fossil hunters working from the late Victorian era into the early 20th century. Fossil dinosaur expeditions Sponsored by the American Museum of Natural History (AMNH), Brown traversed the country bargaining and trading for fossils. His field was not limited to dinosaurs. He was known to collect or obtain anything of possible scientific value. Often, he simply sent money to have fossils shipped to the AMNH, and any new specimen of interest often resulted in a flurry of letters between the discoverer and Brown. After working a handful of years in Wyoming for AMNH in the late 1890s, Brown led an expedition to the Hell Creek Formation of southeastern Montana. There, in 1902, he discovered and excava ...

Saurolophus
''Saurolophus'' (; meaning "lizard crest") is a genus of large hadrosaurid dinosaur from the Late Cretaceous period of Asia and North America, that lived in what is now the Horseshoe Canyon and Nemegt formations about 70 million to 68 million years ago. It is one of the few genera of dinosaurs known from multiple continents. The type species, ''S. osborni'', was described by Barnum Brown in 1912 from Canadian fossils. A second valid species, ''S. angustirostris'', is represented by numerous specimens from Mongolia, and was described by Anatoly Konstantinovich Rozhdestvensky. ''Saurolophus'' is distinguished by a spike-like crest which projects up and back from the skull. It was a herbivorous dinosaur which could move about either bipedally or quadrupedally. Discovery and history Barnum Brown recovered the first described remains of ''Saurolophus'' in 1911, including a nearly complete skeleton ( AMNH 5220). Now on display in the American Museum of Natural History, this s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tritheledon
''Tritheledon'' is an extinct genus of cynodonts that lived during the Lower Jurassic. Fossils were found in the Elliot Formation, South Africa. Like all cynodonts, it had many traits shared by mammals. Tritheledonts were probably insectivores, and nocturnal Nocturnality is an ethology, animal behavior characterized by being active during the night and sleeping during the day. The common adjective is "nocturnal", versus diurnality, diurnal meaning the opposite. Nocturnal creatures generally have ... animals.Luo, Z-X, Z Kielan-Jaworowska & RL Cifelli (2002), In quest for a phylogeny of Mesozoic mammals. ''Acta Palaeontol. Pol''. 47: 1-78.

Taurops
''Tapinocephalus'' ("humble head") is an extinct genus of large herbivorous dinocephalians that lived during the Middle Permian Period. These stocky, barrel-bodied animals were characterised by a massive bony skull roof and short weak snout. It is thought that, like the rest of the members of its family, the animals engaged in head-butting intraspecific behavior, possibly for territory or mates. The fossil remains (skull and postcranial elements) of ''Tapinocephalus'' are known from the Lower, Middle, and Upper part of the ''Tapinocephalus'' Assemblage Zone ( Capitanian age) of the Lower Beaufort Beds of the South African Karoo. Only the type species, ''T. atherstonei'' is now considered valid for this genus. In life, these animals were over in length and massed around , making them among the largest animals of their time. Classification ''Tapinocephalus atherstonei'' is known from a number of skulls and postcranial bones. The skull is large with a heavily pachyostotic ...

Thrinaxodon
''Thrinaxodon'' is an extinct genus of cynodonts, most commonly regarded by its species ''T. liorhinus'' which lived in what are now South Africa and Antarctica during the Early Triassic. ''Thrinaxodon'' lived just after the Permian–Triassic mass extinction event, its survival during the extinction may have been due to its burrowing habits. Similar to other therapsids, ''Thrinaxodon'' adopted a semi-sprawling posture, an intermediary form between the sprawling position of basal tetrapods (still observed modern Crocodilia) and the more upright posture present in current mammals.Blob R. 2001. Evolution of hindlimb posture in non-mammalian therapsids: biomechanical tests of paleontological hypotheses. 27(1): 14-38. ''Thrinaxodon'' is prevalent in the fossil record in part because it was one of the few carnivores of its time, and was of a larger size than similar cynodont carnivores. Description ''Thrinaxodon'' was a small synapsid roughly the size of a fox and possibly covered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galeops
''Galeops'' is an extinct genus of anomodont therapsids from the Middle-Late Permian of South Africa. It was described by Robert Broom Robert Broom FRS FRSE (30 November 1866 6 April 1951) was a British- South African doctor and palaeontologist. He qualified as a medical practitioner in 1895 and received his DSc in 1905 from the University of Glasgow. From 1903 to 1910, he ... in 1912. Some cladistic analyses have recovered it as closely related to dicynodonts.

Emydops
''Emydops'' is an extinct genus of dicynodont therapsid from the Permian of South Africa. ''Emydops'' was first named by South African paleontologist Robert Broom in 1912 when he described ''Emydops minor''. In the following years, the genus grew to include thirteen species. Many of these species were erected on the basis of differences in the teeth and the positioning of the frontal and parietal bones. A 2008 study narrowed ''Emydops'' down to two species, ''E. arctatus'' (first described by English paleontologist Richard Owen as ''Kistecephalus arctatus'' in 1876) and the newly described ''E. oweni''. Both species of ''Emydops'' are small. The skull of ''Emydops'' was 5 cm (2 in) long. Tusks are present in most skulls, but some lack them. The eye sockets are positioned far forward in the skull and face somewhat forward and upward. A wide area on the lower jaw called the lateral dentary shelf is another distinguishing feature of the genus. The temporal regions behind ...
