Plesiadapis
''Plesiadapis'' is one of the oldest known primate-like mammal genera which existed about 58–55 million years ago in North America and Europe. ''Plesiadapis'' means "near-Adapis", which is a reference to the adapiform primate of the Eocene period, ''Adapis''. ''Plesiadapis tricuspidens'', the type specimen, is named after the three cusps present on its upper incisors. Taxonomy The first discovery of ''Plesiadapis'' was made by François Louis Paul Gervaise in 1877, who first discovered ''Plesiadapis tricuspidens'' in France. The type specimen is MNHN Crl-16, and is a left mandibular fragment dated to the early Eocene epoch. This genus probably arose in North America and colonized Europe on a landbridge via Greenland. Thanks to the abundance of the genus and to its rapid evolution, species of ''Plesiadapis'' play an important role in the zonation of Late Paleocene continental sediments and in the correlation of faunas on both sides of the Atlantic.

Primate
Primates are a diverse order of mammals. They are divided into the strepsirrhines, which include the lemurs, galagos, and lorisids, and the haplorhines, which include the tarsiers and the simians (monkeys and apes, the latter including humans). Primates arose 85–55 million years ago first from small terrestrial mammals, which adapted to living in the trees of tropical forests: many primate characteristics represent adaptations to life in this challenging environment, including large brains, visual acuity, color vision, a shoulder girdle allowing a large degree of movement in the shoulder joint, and dextrous hands. Primates range in size from Madame Berthe's mouse lemur, which weighs , to the eastern gorilla, weighing over . There are 376–524 species of living primates, depending on which classification is used. New primate species continue to be discovered: over 25 species were described in the 2000s, 36 in the 2010s, and three in the 2020s. Primates have large bra ...

Museum Of Natural Sciences
The Museum of Natural Sciences of Belgium (french: Muséum des sciences naturelles de Belgique, nl, Museum voor Natuurwetenschappen van België) is a museum dedicated to natural history, located in Brussels, Belgium. The museum is a part of the Royal Belgian Institute of Natural Sciences. Its most important pieces are 30 fossilised ''Iguanodon'' skeletons, which were discovered in 1878 in Bernissart, Belgium. The Dinosaur Hall of the museum is the world's largest museum hall completely dedicated to dinosaurs. Another famous piece is the Ishango bone, which was discovered in 1960 by Jean de Heinzelin de Braucourt in the Belgian Congo. The museum also houses a research department and a public exhibit department. History The Museum of Natural Sciences was founded on 31 March 1846, as a descendant of the ''Musée de Bruxelles'' of 1802. It was based on the collection established by Prince Charles Alexander of Lorraine, dating from the 18th century. The scientist and politician Be ...

Badwater Basin
Badwater Basin is an endorheic basin in Death Valley National Park, Death Valley, Inyo County, California, noted as the lowest point in North America and the United States, with a depth of below sea level. Mount Whitney, the highest point in the contiguous United States, is only to the northwest. The site itself consists of a small spring-fed pool of "bad water" next to the road in a sink; the accumulated salts of the surrounding basin make it undrinkable, thus giving it the name. The pool does have animal and plant life, including pickleweed, aquatic insects, and the Badwater snail. Adjacent to the pool, where water is not always present at the surface, repeated freeze–thaw and evaporation cycles gradually push the thin salt crust into hexagonal honeycomb shapes. The pool is not the lowest point of the basin: the lowest point (which is only slightly lower) is several miles to the west and varies in position, depending on rainfall and evaporation patterns. The salt fla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paskapoo Formation
The Paskapoo Formation is a stratigraphic unit of Middle to Late Paleocene age in the Western Canada Sedimentary Basin. The Paskapoo underlies much of southwestern Alberta, and takes the name from the Blindman River (''paskapoo'' means "blind man" in Cree). It was first described from outcrops along that river, near its confluence with the Red Deer River north of the city of Red Deer, by J.B. Tyrrell in 1887.Tyrrell, J.B., 1887. ''Report on a part of northern Alberta and portions of adjacent Districts of Assiniboia and Saskatchewan;'' Geological Survey of Canada, Annual Report 1886, v.11, Part E, p.1-176 It is important for its freshwater aquifers, its coal resources, and its fossil record, as well as having been the source of sandstone for the construction of fire-resistant buildings in Calgary during the early 1900s. Lithology and environment of deposition The Paskapoo Formation is of fluvial origin and consists primarily of sandstones, siltstones and mudstones, with lesser amo ...

Togwotee Pass
Togwotee Pass (pronounced TOH-guh-tee) is a high mountain pass in the western United States, at an elevation of above sea level. On the Continental Divide in the Absaroka Mountains of northwestern Wyoming in Teton County, it is between Dubois and Moran Junction in the Jackson Hole valley. U.S. Highways 287 and 26 traverse the pass, which is approximately east of Moran Junction. The pass provides the most direct access to Grand Teton National Park from eastern Wyoming. Located between Two Ocean Mountain and Breccia Peak, sweeping vistas of the Teton Range are visible from the western slopes of the pass. A ski run (mainly a traverse) at the Jackson Hole ski resort is also named Togwotee Pass Located in the Bridger-Teton National Forest and adjacent to Shoshone National Forest, the pass receives heavy winter snowfall and is a top destination for snowmobiling and cross-country skiing. Annual snowfall at the pass often exceeds (reports of over of snow are also k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bearcreek, Montana
Bearcreek is an incorporated town in Carbon County, Montana, United States. It is part of the Billings, Montana Metropolitan Statistical Area. The population was 91 at the 2020 census. Bearcreek uses the Mayor/Council form of government. The town of Bearcreek was named for Bear Creek, which runs through the middle of town. Bearcreek came into existence due to coal mines and grew rapidly following the building of a short line railroad connecting the Bearcreek mines to the Northern Pacific Railroad in 1906. Between 1906 and 1953, the mines at Bearcreek produced large volumes of coal, which was a higher grade than other regional sources, from the extensive underground coal mining deposits. The mines were located along the creek and also in the surrounding coulees. The development of the coal mines after 1906 drew miners to the area. They came from other parts of America, and from Serbia, Montenegro, Germany, Scotland and Italy. The recent immigrants built separate ethnic-based co ...
