Chiayusaurus
''Chiayusaurus'' (meaning " Chia-yu-kuan lizard", after where it was found) is a genus of sauropod dinosaur known from teeth found in China and possibly also South Korea. Two species have been named for this obscure genus, though only the type, ''C. lacustris'', is still seen as valid. It was originally named as ''Chiayüsaurus'', but the ICZN does not permit special characters, so the name was corrected to ''Chiayusaurus''. The obsolete name can still be seen in older sources, though. As a sauropod, ''Chiayusaurus'' would have been a large, quadrupedal herbivore. History and taxonomy Birger Bohlin based ''Chiayusaurus'' on a tooth crown in the IVPP. This tooth was found in the Barremian-age (Early Cretaceous) Xinminbao Group of Gansu, China. This spatulate tooth crown was long, and was not similar to the younger genus '' Asiatosaurus''. As it was based on such sparse material, it has largely been ignored or considered to be indistinguishable from other, better-known sauropods. F ...

Hasandong Formation
The Hasandong Formation () is an Early Cretaceous ( Aptian to Albian) geologic formation in South Korea. It has been dated to the late Aptian and earliest Albian, between 118.0 ± 2.6 Ma and 112.4 ± 1.3 Ma. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation. Tracks of the pterosaur ichnospecies ''Pteraichnus koreanensis'' have also been recovered from the unit.Y.-N. Lee, H.-J. Lee, J. and Y. Kobayashi. 2008.

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] |
Gansu
Gansu (, ; alternately romanized as Kansu) is a province in Northwest China. Its capital and largest city is Lanzhou, in the southeast part of the province. The seventh-largest administrative district by area at , Gansu lies between the Tibetan and Loess plateaus and borders Mongolia ( Govi-Altai Province), Inner Mongolia and Ningxia to the north, Xinjiang and Qinghai to the west, Sichuan to the south and Shaanxi to the east. The Yellow River passes through the southern part of the province. Part of Gansu's territory is located in the Gobi Desert. The Qilian mountains are located in the south of the Province.

Euhelopus
''Euhelopus'' is a genus of sauropod dinosaur that lived between 145 and 133 million years ago during the Berriasian and Valanginian stages of the Early Cretaceous in what is now Shandong Province in China. It was a large quadrupedal herbivore. Unlike most other sauropods, ''Euhelopus'' had longer forelegs than hind legs. This discovery was paleontologically significant because it represented the first dinosaur scientifically investigated from China: seen in 1913, rediscovered in 1922, and excavated in 1923 and studied by T'an during the same year.T'an, H. C. (1923). New research on the Mesozoic and early Tertiary geology in Shantung. Geological Survey of China Bulletin 5:95-135 Unlike most sauropod specimens, it has a relatively complete skull. ''Euhelopus'' was a long-necked sauropod similar to ''Mamenchisaurus'', but its affinities are controversial. Most studies favor a close relationship between ''Euhelopus'' and titanosaurs, rather than mamenchisaurids. Description Size ...

Gyeongsang
Gyeongsang ( ko, 경상도, ''Gyeongsang-do''; ) was one of the eight provinces of Korea during the Joseon dynasty. Gyeongsang was located in the southeast of Korea. The provincial capital was Daegu. The region was the birthplace of the Kingdom of Silla. The region also has a significant role in modern Korean history, since seven previous South Korean presidents (Park Chung-hee, Roh Tae-woo, Chun Doo-hwan, Kim Young-sam, Roh Moo-hyun, Park Geun-hye, and Moon Jae-in) were born in the Gyeongsang region. Today, the region is divided into 5 administrative divisions: the three independent cities of Busan, Daegu and Ulsan, and the two provinces of Gyeongsangbuk-do and Gyeongsangnam-do. The largest city in the region is Busan, followed by Daegu. Sub-regionally, the region is also divided into Gyeongbuk and Gyeongnam. Gyeongbuk consists of Daegu and Gyeongsangbuk-do, while Gyeongnam consists of Busan, Ulsan and Gyeongsangnam-do. History The predecessor to Gyeongsang Province was form ...

Albian
The Albian is both an age of the geologic timescale and a stage in the stratigraphic column. It is the youngest or uppermost subdivision of the Early/Lower Cretaceous Epoch/Series. Its approximate time range is 113.0 ± 1.0 Ma to 100.5 ± 0.9 Ma (million years ago). The Albian is preceded by the Aptian and followed by the Cenomanian. Stratigraphic definitions The Albian Stage was first proposed in 1842 by Alcide d'Orbigny. It was named after Alba, the Latin name for River Aube in France. A Global Boundary Stratotype Section and Point (GSSP), ratified by the IUGS in 2016, defines the base of the Albian as the first occurrence of the planktonic foraminiferan '' Microhedbergella renilaevis'' at the Col de Pré-Guittard section, Arnayon, Drôme, France. The top of the Albian Stage (the base of the Cenomanian Stage and Upper Cretaceous Series) is defined as the place where the foram species '' Rotalipora globotruncanoides'' first appears in the stratigraphic column.

Aptian
The Aptian is an age in the geologic timescale or a stage in the stratigraphic column. It is a subdivision of the Early or Lower Cretaceous Epoch or Series and encompasses the time from 121.4 ± 1.0 Ma to 113.0 ± 1.0 Ma (million years ago), approximately. The Aptian succeeds the Barremian and precedes the Albian, all part of the Lower/Early Cretaceous. The Aptian partly overlaps the upper part of the Western European Urgonian Stage. The Selli Event, also known as OAE1a, was one of two oceanic anoxic events in the Cretaceous Period, which occurred around 120 Ma and lasted approximately 1 to 1.3 million years. The Aptian extinction was a minor extinction event hypothesized to have occurred around 116 to 117 Ma.Archangelsky, Sergio.The Ticó Flora (Patagonia) and the Aptian Extinction Event" ''Acta Paleobotanica'' 41(2), 2001, pp. 115-22.

Type Species
In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name that has that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have such types.

Mamenchisaurus
''Mamenchisaurus'' (or spelling pronunciation ) is a genus of sauropod dinosaur known for their remarkably long necks which made up nearly half the total body length. Numerous species have been assigned to the genus; however, many of these might be questionable. Fossils have been found in the Sichuan Basin and Yunnan Province in China. Several species are from the Upper Shaximiao Formation whose geologic age is uncertain. However, evidence suggests that this be no earlier than the Oxfordian stage of the Late Jurassic. ''M. sinocanadorum'' dates to the Oxfordian stage (158.7 to 161.2 mya) and ''M. anyuensis'' to the Aptian stage of the Early Cretaceous around 114.4 mya. Most species were medium- to large-size sauropods in length.Russell, D.A., Zheng, Z. (1993). "A large mamenchisaurid from the Junggar Basin, Xinjiang, People Republic of China."
