Subei Mongol Autonomous County
The Subei Mongol Autonomous County (; Mongolian: ) is an autonomous county within the prefecture-level city of Jiuquan in the northwest of Gansu Province, China, bordering Xinjiang to the west, Qinghai Province to the southeast and Mongolia's Govi-Altai Province to the north. Containing the northernmost point in Gansu, Subei is split into two non-contiguous sections and has an area of and had approximately 13,046 inhabitants in 2000. To the east it shares a border with Ejin Banner, Alxa League, Inner Mongolia. History In the early 1930s, Birger Bohlin studied the paleontology of the region (then called Taban Buluk). In 1937, Subei '' Shezhiju'' () was established. On July 22, 1950, PLA forces entered the Subei area. The Subei Autonomous District (), predecessor of the Subei Mongol Autonomous County, was established on July 29, 1950. The area became Subei Mongol Autonomous District () in 1953. In 1955, the area became Subei Mongol Autonomous County. In September 1992, with th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Altay Range
The Altai Mountains (), also spelled Altay Mountains, are a mountain range in Central and East Asia, where Russia, China, Mongolia and Kazakhstan converge, and where the rivers Irtysh and Ob have their headwaters. The massif merges with the Sayan Mountains in the northeast, and gradually becomes lower in the southeast, where it merges into the high plateau of the Gobi Desert. It spans from about 45° to 52° N and from about 84° to 99° E. The region is inhabited by a sparse but ethnically diverse population, including Russians, Kazakhs, Altais, Mongols and Volga Germans, though predominantly represented by indigenous ethnic minorities of semi-nomadic stock. The local economy is based on bovine, sheep, horse husbandry, hunting, agriculture, forestry, and mining. The Altaic language family takes its name from this mountain range. Etymology and modern names ''Altai'' is derived from underlying form *''altañ'' "gold, golden" (compare Old Turkic 𐰞𐱃𐰆𐰣 ''altun'' ...

Cold Desert Climate
The desert climate or arid climate (in the Köppen climate classification ''BWh'' and ''BWk''), is a dry climate sub-type in which there is a severe excess of evaporation over precipitation. The typically bald, rocky, or sandy surfaces in desert climates are dry and hold little moisture, quickly evaporating the already little rainfall they receive. Covering 14.2% of earth's land area, hot deserts are the second most common type of climate on earth after the polar climate. There are two variations of a desert climate according to the Köppen climate classification: a hot desert climate (''BWh''), and a cold desert climate (''BWk''). To delineate "hot desert climates" from "cold desert climates", there are three widely used isotherms: most commonly a mean annual temperature of , or sometimes the coldest month's mean temperature of , so that a location with a ''BW'' type climate with the appropriate temperature above whichever isotherm is being used is classified as "hot arid sub ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hadrosauroid Dinosaur
Hadrosauroidea is a clade or superfamily of ornithischian dinosaurs that includes the "duck-billed" dinosaurs, or hadrosaurids, and all dinosaurs more closely related to them than to ''Iguanodon''. Their remains have been recovered in Asia, Europe, Africa and the Americas. Many primitive hadrosauroids, such as the Asian ''Probactrosaurus'' and ''Altirhinus'', have traditionally been included in a paraphyletic (unnatural grouping) "Iguanodontidae". With cladistic analysis, the traditional Iguanodontidae has been largely disbanded, and probably includes only ''Iguanodon'' and perhaps its closest relatives. Classification The cladogram below follows an analysis by Andrew McDonald, 2012, and shows the position of Hadrosauroidea within Styracosterna. The cladogram below follows an analysis by Wu Wenhao and Pascal Godefroit (2012). Cladogram after Prieto-Marquez and Norell (2010). A phylogenetic analysis performed by Ramírez-Velasco ''et al.''

Gongpoquansaurus Mazongshanensis
''Gongpoquansaurus'' (meaning "Gongpoquan reptile") is an extinct genus of basal hadrosauroid dinosaur that was not formally named until 2014, while the name was a ''nomen nudum'' for many years previously. It is known from IVPP V.11333, a partial skull and postcranial skeleton. It was collected in 1992 at locality IVPP 9208–21, from the Albian Zhonggou Formation (Xinminpu Group), in Mazongshan, Gansu Province, China. The specimen was first described and named by Lü Junchang in 1997 as the third species of ''Probactrosaurus'', ''Probactrosaurus mazongshanensis''.Lü J., 1997, "A new Iguanodontidae (''Probactrosaurus mazongshanensis'' sp. nov.) from Mazongshan area, Gansu Province, China", In: Z. Dong (ed.), ''Sino-Japanese Silk Road Dinosaur Expedition''. China Ocean Press, Beijing pp. 27-47 Following its description, several studies found it to be less derived than the type species of ''Probactrosaurus'' in relation to Hadrosauridae Hadrosaurids (), or duck-billed dinosau ...

Equijubus
''Equijubus'' (; ''Mǎzōng'' meaning "horse mane" after the area Mǎzōng Mountain 马鬃山 in which it was found), is a genus of herbivorous hadrosauroid dinosaur from the Early Cretaceous (Albian stage) of northwestern China. Discovery and naming The type (and only known) specimen was found in the summer of 2000 by a Chinese-American expedition in the Mazong (= "horse mane") Shan area of China's Gansu Province.You, Luo, Shubin, Witmer, Tang and Tang (2003). "The earliest-known duck-billed dinosaur from deposits of late Early Cretaceous age in northwest China and hadrosaurid evolution." ''Cretaceous Research'', 24: 347-353. In 2002 You Hialu in a dissertation named and described the species ''Equijubus normani''. The generic name is derived from Latin ''equus'', "horse", and ''juba'', "mane". The specific epithet "normani" is in honour of British palaeontologist David B. Norman. However, such a ''nomen ex dissertatione'' does not constitute a valid name. The type ...

Xinminbao Group
The Xīnmínbǎo Group () is a group of geological formations in north central China. They occur across a large depression (geology), depression between the Altai mountains of Mongolia to the north and the Qilian Shan, Qilian mountains of the Qinghai Plateau to the south, in the Gōngpóquán (公婆泉) and Suànjǐngzi (算井子) Basin (geology), basins, and also in the neighbouring Jiuquan Basin. Both of these areas are inland basins consisting of fluvial (river), Lake, lacustrine (lake), and intermontane (between mountains) alluvial fan (floodplain) sediments that were deposited during the Early Cretaceous, probably during the Aptian or possibly late Barremian faunal stage, stage, when the climate was semi-arid and subtropical. The group has been visited by many expeditions including the Silk Road dinosaur expedition of 1992 which concentrated on the area around Mazong Shan. Geology The group is made up of three main formations. Chijinbao Formation This consists of a lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Ranges Of China
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...
