Davidia Involucrata
''Davidia involucrata'', the dove-tree, handkerchief tree, pocket handkerchief tree, or ghost tree, is a medium-sized deciduous tree in the family Nyssaceae. It is the only living species in the genus ''Davidia''. It was previously included with tupelos in the dogwood family, Cornaceae. Fossil species are known extending into the Upper Cretaceous. Taxonomy ''Davidia involucrata'' is the only member of its genus, but there are two varieties differing slightly in their leaves, ''D. involucrata'' var. ''involucrata'', which has the leaves thinly pubescent (short-haired) on the underside, and ''D. involucrata'' var. ''vilmoriniana'', with glabrous (hairless) leaves. Some botanists treat them as distinct species, with good reason, as the two taxa have differing chromosome numbers so are unable to produce fertile hybrid offspring. Description It is a moderately fast-growing tree, growing to in height, with toothed, alternate, ovate-cordate leaves resembling those of a linden, exce ...

Dove
Columbidae () is a bird family consisting of doves and pigeons. It is the only family in the order Columbiformes. These are stout-bodied birds with short necks and short slender bills that in some species feature fleshy ceres. They primarily feed on seeds, fruits, and plants. The family occurs worldwide, but the greatest variety is in the Indomalayan and Australasian realms. The family contains 344 species divided into 50 genera. Thirteen of the species are extinct. In English, the smaller species tend to be called "doves" and the larger ones "pigeons". However, the distinction is not consistent, and does not exist in most other languages. Historically, the common names for these birds involve a great deal of variation between the terms. The bird most commonly referred to as just "pigeon" is the domestic pigeon, which is common in many cities as the feral pigeon. Doves and pigeons build relatively flimsy nests, often using sticks and other debris, which may be placed on br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dinosaur Provincial Park
Dinosaur Provincial Park is a UNESCO World Heritage Site situated a two hour drive east of Calgary, Alberta, Canada; or , about a half-hour drive northeast of Brooks. The park is situated in the Red Deer River valley, which is noted for its striking badland topography, and abundance of dinosaur fossils. The park is well known for being one of the richest dinosaur fossil locales in the world. Fifty-eight dinosaur species have been discovered at the park and more than 500 specimens have been removed and exhibited in museums around the globe. The renowned fossil assemblage of nearly 500 species of life, from microscopic fern spores to large carnivorous dinosaurs, justified its becoming a World Heritage Site in 1979. Dinosaur Provincial Park Visitor Centre The Dinosaur Provincial Park Visitor Centre features exhibits about dinosaurs, fossils, and the geology and natural history of the park. There is a video theatre, fossil prep lab area, and a gift shop. Public programs are offere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horseshoe Canyon Formation
The Horseshoe Canyon Formation is a stratigraphic unit of the Western Canada Sedimentary Basin in southwestern Alberta. It takes its name from Horseshoe Canyon, an area of badlands near Drumheller. The Horseshoe Canyon Formation is part of the Edmonton Group and is up to thick. It is of Late Cretaceous age, Campanian to early Maastrichtian stage (Edmontonian Land-Mammal Age), and is composed of mudstone, sandstone, carbonaceous shales, and coal seams. A variety of depositional environments are represented in the succession, including floodplains, estuarine channels, and coal swamps, which have yielded a diversity of fossil material. Tidally-influenced estuarine point bar deposits are easily recognizable as Inclined Heterolithic Stratification (IHS). Brackish-water trace fossil assemblages occur within these bar deposits and demonstrate periodic incursion of marine waters into the estuaries. The Horseshoe Canyon Formation crops out extensively in the area around Drumheller, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Campanian
The Campanian is the fifth of six ages of the Late Cretaceous Epoch on the geologic timescale of the International Commission on Stratigraphy (ICS). In chronostratigraphy, it is the fifth of six stages in the Upper Cretaceous Series. Campanian spans the time from 83.6 (± 0.2) to 72.1 (± 0.2) million years ago. It is preceded by the Santonian and it is followed by the Maastrichtian. The Campanian was an age when a worldwide sea level rise covered many coastal areas. The morphology of some of these areas has been preserved: it is an unconformity beneath a cover of marine sedimentary rocks. Etymology The Campanian was introduced in scientific literature by Henri Coquand in 1857. It is named after the French village of Champagne in the department of Charente-Maritime. The original type locality was a series of outcrop near the village of Aubeterre-sur-Dronne in the same region. Definition The base of the Campanian Stage is defined as a place in the stratigraphic colu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Permineralized
Permineralization is a process of fossilization of bones and tissues in which mineral deposits form internal casts of organisms. Carried by water, these minerals fill the spaces within organic tissue. Because of the nature of the casts, permineralization is particularly useful in studies of the internal structures of organisms, usually of plants. Process Permineralization, a type of fossilization, involves deposits of minerals within the cells of organisms. Water from the ground, lakes, or oceans seeps into the pores of organic tissue and forms a crystal cast with deposited minerals. Crystals begin to form in the porous cell walls. This process continues on the inner surface of the walls until the central cavity of the cell, the lumen, is completely filled. The cell walls themselves remain intact surrounding the crystals. Silicification In silicification, the weathering of rocks releases silicate minerals and the silica makes its way into a body of still water. Eventually, the ...

Ernest Henry Wilson
Ernest Henry "Chinese" Wilson (15 February 1876 – 15 October 1930), better known as E. H. Wilson, was a notable British plant collector and explorer who introduced a large range of about 2000 Asian plant species to the West; some sixty bear his name. Career Wilson was born in Chipping Campden, Gloucestershire but the family soon moved to Shirley, Warwickshire, where they set up a floristry business. He left school early for employment at the local nursery of Messrs. Hewitt, Warwickshire, as apprentice gardener, and, aged 16, at the Birmingham Botanical Gardens; there he also studied at Birmingham Municipal Technical School in the evenings, receiving the Queen's Prize for botany. In 1897 he began work at the Royal Botanic Gardens, Kew, where he won the Hooker Prize for an essay on conifers. He then accepted a position as Chinese plant collector with the firm of James Veitch & Sons, who were eager above all to retrieve the dove tree, '' Davidia involucrata''. "Stick to the ...

Augustine Henry
Augustine Henry (2 July 1857 – 23 March 1930) was a British-born Irish plantsman and sinologist. He is best known for sending over 15,000 dry specimens and seeds and 500 plant samples to Kew Gardens in the United Kingdom. By 1930, he was a recognised authority and was honoured with society membership in Belgium, Czechoslovakia, Finland, France, and Poland. In 1929 the Botanical Institute of Peking dedicated to him the second volume of ''Icones plantarum Sinicarum'', a collection of plant drawings. In 1935, ''John William Besant'' was to write: 'The wealth of beautiful trees and flowering shrubs which adorn gardens in all temperate parts of the world today is due in a great measure to the pioneer work of the late Professor Henry'.Besant, J. W. (1935) 'Plantae Henryanae', ''Gard. Chron.'' 98 (9 November 1935): 334–335. Early life and education Henry was born on 2 July 1857 in Dundee, Scotland to Bernard (a flax merchant) and Mary (née McManee) Henry; the family returned to ...

Vincentian Family
The Vincentian Family comprises organizations inspired by the life and work of Vincent de Paul, a 17th-century priest who "transformed the face of France." He directly founded the Confraternities of Charity (today known as the AIC) the Congregation of the Mission and the Daughters of Charity of Saint Vincent de Paul. Frederic Ozanam, inspired by a Daughter of Charity, Rosalie Rendu, founded the Society of St. Vincent de Paul. Betty Ann McNeil, DC, has written a definitive work identifying some 268 institutes that meet at least one criterion as members of the Vincentian Family. The Vincentian Family, ''inter alia'', has, as its incumbent head, Tomaž Mavrič of Buenos Aires, the incumbent worldwide superior general of the Congregation of the Mission, elected during the community's 42nd General Assembly (June 27 – July 15, 2016) in Chicago.

Armand David
Father Armand David (7 September 1826, Espelette – 10 November 1900, Paris) was a Lazarist missionary Catholic priest as well as a zoologist and a botanist. Several species, such as Père David's deer, are named after him — being French for Father David. Biography Born in Espelette near Bayonne, in the north of Basque Country, in Pyrénées-Atlantiques ''département'' of France, he entered the Congregation of the Mission in 1848, having already displayed great fondness for the natural sciences. Ordained in 1851, he was in 1862 sent to Peking, where he began a collection of material for a museum of natural history, mainly zoological, but in which botany, geology, and palaeontology were also well represented. At the request of the French government, important specimens from his collection were sent to Paris and aroused the greatest interest. The Jardin des Plantes commissioned him to undertake scientific journeys through China to make further collecti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
