Driftwood Canyon Provincial Park
Driftwood Canyon Provincial Park is a provincial park in British Columbia, Canada. Driftwood Canyon Provincial Park covers 23 ha of the Bulkley River Valley, on the east side of Driftwood Creek, a tributary of the Bulkley River, 10 km northeast of the town of Smithers. The park is accessible from Driftwood Road from Provincial Highway 16. It was created in 1967 by the donation of the land by the late Gordon Harvey (1913–1976) to protect fossil beds on the east side of Driftwood Creek. The beds were discovered around the beginning of the 20th century. The park lands are part of the asserted traditional territory of the Wet'suwet'en First Nation.Ludvigsen, R. 2001.

Aphididae
The Aphididae are a very large insect family in the aphid superfamily ( Aphidoidea), of the order Hemiptera. These insects suck the sap from plant leaves. Several thousand species are placed in this family, many of which are considered plant/crop pests. They are the family of insects containing most plant virus vectors (around 200 known) with the green peach aphid (''Myzus persicae'') being one of the most prevalent and indiscriminate carriers. Evolution Aphids originated in the late Cretaceous about (Mya), but the Aphidinae which comprises about half of the 4700 described species and genera of aphids alive today come from their most recent radiation which occurred in the late Tertiary less than 10 Mya.Von Dohlen CD, Moran NA (2000) Molecular data support a rapid radiation of aphids in the Cretaceous and multiple origins of host alternation.

Aphids
Aphids are small sap-sucking insects and members of the superfamily Aphidoidea. Common names include greenfly and blackfly, although individuals within a species can vary widely in color. The group includes the fluffy white woolly aphids. A typical life cycle involves flightless females giving live birth to female nymphs—who may also be already pregnant, an adaptation scientists call telescoping generations—without the involvement of males. Maturing rapidly, females breed profusely so that the number of these insects multiplies quickly. Winged females may develop later in the season, allowing the insects to colonize new plants. In temperate regions, a phase of sexual reproduction occurs in the autumn, with the insects often overwintering as eggs. The life cycle of some species involves an alternation between two species of host plants, for example between an annual crop and a woody plant. Some species feed on only one type of plant, while others are generalists, coloni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gerridae
The Gerridae are a family of insects in the order Hemiptera, commonly known as water striders, water skeeters, water scooters, water bugs, pond skaters, water skippers, or water skimmers. Consistent with the classification of the Gerridae as true bugs (i.e., suborder Heteroptera), gerrids have mouthparts evolved for piercing and sucking, and distinguish themselves by having the unusual ability to walk on water, making them pleuston (surface-living) animals. They are anatomically built to transfer their weight to be able to run on top of the water's surface. As a result, one could likely find water striders present in any pond, river, or lake. Over 1,700 species of gerrids have been described, 10% of them being marine. While 90% of the Gerridae are freshwater bugs, the oceanic '' Halobates'' makes the family quite exceptional among insects. The genus ''Halobates'' was first heavily studied between 1822 and 1883 when Buchanan-White collected several different species during th ...

Eosalmo
''Eosalmo'' is an extinct genus of ancient salmonid that lived during the Eocene epoch. The genus was first described in 1977 from fossils found in lacustrine deposits in Driftwood Canyon Provincial Park, near Smithers, British Columbia, Canada, leading to the specific epithet ''E. driftwoodensis''. Fossils from this genus have also been found at sites in Princeton, British Columbia, the McAbee Fossil Beds in B.C., and Republic, Washington, USA. When first described the genus was thought to be intermediate in form to the extant salmonid subfamilies Salmoninae (trout and salmon) and Thymallinae ( graylings). More recent review of the genus has placed ''Eosalmo'' as the most primitive member of the Salmoninae subfamily. Fossils found in Driftwood Canyon Provincial Park display a full range of individuals from young juveniles through adults. This range indicates that the genus was completely freshwater dwelling and did not spend time in saltwater. Morphology Several uni ...

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 ...

Bowfin
The bowfin (''Amia calva'') is a bony fish, native to North America. Common names include mudfish, mud pike, dogfish, grindle, grinnel, swamp trout, and choupique. It is regarded as a relict, being the sole surviving species of the Halecomorphi, a group of fish that first appeared during the Early Triassic, around 250 million years ago. The bowfin is often considered a "primitive fish" because they have retained some morphological characteristics of their early ancestors. The closest living relatives of bowfins are gars, with the two groups being united in the clade Holostei. Bowfins are demersal freshwater piscivores, commonly found throughout much of the eastern United States, and in southern Ontario and Quebec. Fossil deposits indicate Amiiformes were once widespread in both freshwater and marine environments across North and South America, Europe, Asia, and Africa. Now, their range is limited to much of the eastern United States and adjacent southern Canada, including th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Cenozoic Era
The Cenozoic ( ; ) is Earth's current geological era, representing the last 66million years of Earth's history. It is characterised by the dominance of mammals, birds and flowering plants, a cooling and drying climate, and the current configuration of continents. It is the latest of three geological eras since complex life evolved, preceded by the Mesozoic and Paleozoic. It started with the Cretaceous–Paleogene extinction event, when many species, including the non-avian dinosaurs, became extinct in an event attributed by most experts to the impact of a large asteroid or other celestial body, the Chicxulub impactor. The Cenozoic is also known as the Age of Mammals because the terrestrial animals that dominated both hemispheres were mammalsthe eutherians (placentals) in the northern hemisphere and the metatherians (marsupials, now mainly restricted to Australia) in the southern hemisphere. The extinction of many groups allowed mammals and birds to greatly diversify so that l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geological Survey Of Canada
The Geological Survey of Canada (GSC; french: Commission géologique du Canada (CGC)) is a Canadian federal government agency responsible for performing geological surveys of the country, developing Canada's natural resources and protecting the environment. A branch of the Earth Sciences Sector of Natural Resources Canada, the GSC is the country's oldest scientific agency and was one of its first government organizations. History In September 1841, the Province of Canada legislature passed a resolution that authorized the sum of £1,500 sterling be granted to the government for the estimated expense of performing a geological survey of the province. In 1842, the Geological Survey of Canada was formed to fulfill this request.Christy Vodden (1992)No Stone Unturned: The First 150 years of the Geological Survey of Canada Geological Survey of Canada Web site William Edmond Logan was in Montreal at the time and made it known that he was interested in participating in this survey.
