Amyzon (fish)
''Amyzon'' is an extinct genus belonging to the sucker family Catostomidae first described in 1872 by E. D. Cope. There are six valid species in the genus. ''Amyzon'' are found in North American fossil sites dated from the Early Eocene in Montana and Washington USA, as well as the British Columbian sites at McAbee Fossil Beds, Driftwood Canyon, and the " Horsefly shale", as well as Early Oligocene sites in Nevada USA. One Middle Eocene species is known from the Xiawanpu Formation of China. The Ypresian species ''A. brevipinne'' of the Allenby Formation was redescribed in 2021 and moved to a separate monotypic genus '' Wilsonium''. Species There are six valid species included in ''Amyzon'' with up to nine species having been described. * ''A. aggregatum'' Early Eocene (Ypresian), Horsefly Beds, Horsefly, B.C. * ''A. commune'' late Eocene Florissant Formation, Colorado (junior synonyms ''A. fusiforme'' Cope, 1875 & ''A. pandatum'' Cope, 1874 ) * ''A. gosiutensis'' Eocene Gr ...

Edward Drinker Cope
Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontologist, comparative anatomist, herpetologist, and ichthyologist. Born to a wealthy Quaker family, Cope distinguished himself as a child prodigy interested in science; he published his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations. Cope married his cousin and had one child; the family moved from Philadelphia to Haddonfield, New Jersey, although Cope would maintain a residence and museum in Philadelphia in his later years. Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the American West, prospecting in the 1870s and 1880s, often as a member of United States Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competition ...

Horsefly Shales
Horse-flies or horseflies are true flies in the family Tabanidae in the insect order Diptera. They are often large and agile in flight, and only the female horseflies bite animals, including humans, to obtain blood. They prefer to fly in sunlight, avoiding dark and shady areas, and are inactive at night. They are found all over the world except for some islands and the polar regions (Hawaii, Greenland, Iceland). Both horse-flies and botflies (Oestridae) are sometimes referred to as gadflies. Adult horse-flies feed on nectar and plant exudates; the males have weak mouthparts and only the females bite animals to obtain enough protein from blood to produce eggs. The mouthparts of females are formed into a stout stabbing organ with two pairs of sharp cutting blades, and a spongelike part used to lap up the blood that flows from the wound. The larvae are predaceous and grow in semiaquatic habitats. Female horse-flies can transfer blood-borne diseases from one animal to another ...

Fish Of North America
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...

Tulameen River
The Tulameen River is a tributary of the Similkameen River in the Canadian province of British Columbia. The Tulameen River is part of the Columbia River drainage basin, being a tributary of the Similkameen River, which flows into the Okanagan River, which flows into the Columbia River. Course The Tulameen River originates in E. C. Manning Provincial Park with headwaters at Punchbowl Lake, in the North Cascades part of the Cascade Range. it flows generally north then east, passing Tulameen, British Columbia before joining the Similkameen River at Princeton. It is the only place in the world where both gold and platinum can be found alongside each other, however all significant deposits have been mined. Ecology The watershed holds a number of diverse flora and fauna species. Fauna include mammals, amphibians, reptiles and birds. Among the amphibians of the watershed is the Rough-skinned newt, '' Taricha granulosa'', whose populations in the North Cascades exhibit an adult p ...

Osino Oil Shales
Osino is a town and the capital of Fanteakwa South district, of the Eastern region of Ghana Ghana (; tw, Gaana, ee, Gana), officially the Republic of Ghana, is a country in West Africa. It abuts the Gulf of Guinea and the Atlantic Ocean to the south, sharing borders with Ivory Coast in the west, Burkina Faso in the north, and To ..., located on the Accra-Kumasi highway between Anyinam and Bunsu Junction. It is a semi-rural agrarian setting popular for the street-hawking of the sweetened boiled maize dough delicacy known as the "Osino Graphic".

Kishenehn Formation
The Kishenehn Formation is a Paleogene stratigraphic unit in Montana. Fossil amiiforme and teleost fish have been found in outcrops of the formation's Coal Creek Member in Glacier National Park. Mosquitos have also been found in the Coal Creek Member, and have been found to be hematophagous. It is considered a Middle Eocene Lagerstätte. Footnotes References *Hunt, ReBecca K., Vincent L.

Green River Formation
The Green River Formation is an Eocene geologic formation that records the sedimentation in a group of intermountain lakes in three basins along the present-day Green River in Colorado, Wyoming, and Utah. The sediments are deposited in very fine layers, a dark layer during the growing season and a light-hue inorganic layer in the dry season. Each pair of layers is called a varve and represents one year. The sediments of the Green River Formation present a continuous record of six million years. The mean thickness of a varve here is 0.18 mm, with a minimum thickness of 0.014 mm and maximum of 9.8 mm.Bradley, W. H. The varves and climate of the Green River epoch: U.S. Geol. Survey Prof. Paper 158, pp 87–110, 1929. The sedimentary layers were formed in a large area named for the Green River, a tributary of the Colorado River. The three separate basins lie around the Uinta Mountains (north, east, and south) of northeastern Utah: * an area in northwestern Colorado east ...

Florissant Formation
The Florissant Formation is a sedimentary geologic formation outcropping around Florissant, Teller County, Colorado. The formation is noted for the abundant and exceptionally preserved insect and plant fossils that are found in the mudstones and shales. Based on argon radiometric dating, the formation is Eocene (approximately 34 million years old ) in age and has been interpreted as a lake environment. The fossils have been preserved because of the interaction of the volcanic ash from the nearby Thirtynine Mile volcanic field with diatoms in the lake, causing a diatom bloom. As the diatoms fell to the bottom of the lake, any plants or animals that had recently died were preserved by the diatom falls. Fine layers of clays and muds interspersed with layers of ash form "paper shales" holding beautifully-preserved fossils. The Florissant Fossil Beds National Monument is a national monument established to preserve and study the geology and history of the area. History The name ''Fl ...
