Champsosaurus Gigas
''Champsosaurus'' is an extinct genus of crocodile-like choristodere reptile, known from the Late Cretaceous and early Paleogene periods of North America and Europe ( Campanian- Paleocene). The name ''Champsosaurus'' is thought to come from , () said in an Ancient Greek source to be an Egyptian word for "crocodiles", and , () Greek for "lizard". The morphology of ''Champsosaurus'' resembles that of gharials, with a long, elongated snout. It was native to freshwater environments where it likely preyed on fish, similar to living gharials. History of research ''Champsosaurus'' was the first member of the Choristodera to be described. ''Champsosaurus'' was named by Edward Drinker Cope in 1876, from isolated vertebrae found in Late Cretaceous strata of the Judith River Formation on the banks of the Judith River in Fergus County, Montana. Cope designated ''C. annectens'' as the type species rather than the first named ''C. profundus'' due to the larger number of vertebrae he attrib ...

Canadian Museum Of Nature
The Canadian Museum of Nature (french: Musée canadien de la nature; CMN) is a national natural history museum based in Canada's National Capital Region. The museum's exhibitions and public programs are housed in the Victoria Memorial Museum Building, a structure in Ottawa, Ontario. The museum's administrative offices and scientific centres are housed at a separate location, the Natural Heritage Campus, in Gatineau, Quebec. The museum originated from a museum established by the Geological Survey of Canada in 1856. Originally based in Montreal, the museum relocated to downtown Ottawa in 1881. In 1911, the museum relocated to Victoria Memorial Museum Building. Initially a natural history museum, the institution later expanded to include an anthropology and human history department; with the institution renamed the National Museum of Canada in 1927. The departments of the national museum were later split into separate national institutions, with the natural history department for ...

Alberta
Alberta ( ) is one of the thirteen provinces and territories of Canada. It is part of Western Canada and is one of the three prairie provinces. Alberta is bordered by British Columbia to the west, Saskatchewan to the east, the Northwest Territories (NWT) to the north, and the U.S. state of Montana to the south. It is one of the only two landlocked provinces in Canada (Saskatchewan being the other). The eastern part of the province is occupied by the Great Plains, while the western part borders the Rocky Mountains. The province has a predominantly continental climate but experiences quick temperature changes due to air aridity. Seasonal temperature swings are less pronounced in western Alberta due to occasional Chinook winds. Alberta is the fourth largest province by area at , and the fourth most populous, being home to 4,262,635 people. Alberta's capital is Edmonton, while Calgary is its largest city. The two are Alberta's largest census metropolitan areas. More tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Dinosaur Park Formation
The Dinosaur Park Formation is the uppermost member of the Belly River Group (also known as the Judith River Group), a major geologic unit in southern Alberta. It was deposited during the Campanian stage of the Late Cretaceous, between about 76.5 and 74.4 million years ago. It was deposited in alluvial and coastal plain environments, and it is bounded by the nonmarine Oldman Formation below it and the marine Bearpaw Formation above it.Eberth, D.A. 2005. The geology. In: Currie, P.J., and Koppelhus, E.B. (eds), Dinosaur Provincial Park: A Spectacular Ancient Ecosystem Revealed. Indiana University Press: Bloomington and Indianapolis, p.54-82. . The Dinosaur Park Formation contains dense concentrations of dinosaur skeletons, both articulated and disarticulated, which are often found with preserved remains of soft tissues. Remains of other animals such as fish, turtles, and crocodilians, as well as plant remains, are also abundant. The formation has been named after Dinosaur Pr ...

Golden Valley County, North Dakota
Golden Valley County is a county in the U.S. state of North Dakota. As of the 2020 census, the population was 1,736,} making it the fourth-least populous county in North Dakota. The county seat is Beach. The county should not be confused with the city of Golden Valley, which is located in Mercer County. History In the general election held November 8, 1910, the voters of Billings County chose to separate the western portion of Billings and form a new county. This result was immediately challenged in court; on September 19, 1912, the ND Supreme Court upheld the election result; therefore the legislature completed the county's organization on November 13, 1912. Golden Valley was called 'Rattlesnake Flats' by early settlers, due to the large number of the snakes found in the area. The region was dubbed Golden Valley in 1902 after a group of land surveyors noticed that the sunlight gave the surrounding grasses a distinct golden color. Retrieved via Ancestry.com.

Bruce Erickson
Bruce R. Erickson (1933 – January 16, 2022) was an American paleontologist and the former Fitzpatrick Chair of Paleontology at the Science Museum of Minnesota. During the course of his lifetime and his 55 years as a paleontologist, he has "collected about a million specimens" and discovered fifteen new types of plants and ancient animal species. His collection includes "a triceratops skeleton" that he discovered in 1961 at the Hell Creek Formation that is considered to be "one of the rarest in the world".Estrada, Heron Marquez"Book fleshes out a career studying dinosaur bones" Star Tribune, April 27, 2003 His research has focused almost entirely on the Paleocene era in history. Biography According to Erickson, his interest in paleontology began when he was ten years old and he came across a geologist investigating rocks along the bank of the Mississippi River.Brody, Jane E."26 Years Deep in the Paleocene" Los Angeles Times, September 3, 1996 Career In the 1960s, Erickson spent ...

Denise Sigogneau-Russell
Denise Sigogneau-Russell (born ''c.'' 1941/42) is a French palaeontologist who specialises in mammals from the Mesozoic, particularly from France and the UK. She is currently based at the Muséum National d'Histoire Naturelle. Background Denise Sigogneau-Russell completed her PhD in 1969 on therapsids - the forerunners of mammals - from South Africa, where she spent two years. In 1976 a Belgian amateur fossil hunter brought her a mammal tooth from a quarry in eastern France, and this inspired her to change direction and begin research on mammals from the Mesozoic.Kielan-Jaworowska, Z. 2013. ''In Pursuit of Early Mammals''. Indiana University Press. She subsequently studied them in France, Portugal, Madagascar, Morocco, and England. Zofia Kielan-Jaworowska said that due to Sigogneau-Russell's "scholarship and diligence, she has contributed enormously to the knowledge of early mammal evolution.". She was married to Donald E.

Red Deer River
The Red Deer River is a river in Alberta and a small portion of Saskatchewan, Canada. It is a major tributary of the South Saskatchewan River and is part of the larger Saskatchewan-Nelson system that empties into Hudson Bay. Red Deer River has a total length of and a drainage area of . Its mean discharge is . The river got its name from the translation of ''Was-ka-soo seepee'' which means "elk river" in the Cree language. "Red deer" was an alternative name for elk, referring to a closely related Eurasian species. Communities located along the Red Deer River include Sundre, Red Deer, Drumheller, and Empress, The city of Brooks, as well as Dinosaur Provincial Park, are also located in the Red Deer River Basin. A glacial flood about 18,000 years ago eroded out a portion of this basin and apparently all or most of the scenic badlands bearing the dinosaur and other Cretaceous fossils.
