Datousaurus
''Datousaurus'' (meaning "chieftain lizard" or "big-head lizard"; originally named using the Malay ''datu'', after its Chinese nickname ''qiulong'' - literally "chieftain dragon" - but also a pun on its big head; ''da tou'' means "big head" in Chinese) was a dinosaur from the Middle Jurassic. It was a sauropod collected from the Lower Shaximiao Formation in Dashanpu, Zigong Sichuan province, China. It shared the local Middle Jurassic landscape with other sauropods such as ''Shunosaurus'', ''Omeisaurus'', '' Protognathosaurus'', the ornithopod ''Xiaosaurus'', the early stegosaur ''Huayangosaurus'' as well as the carnivorous ''Gasosaurus''. Discovery and species ''Datousaurus'' was named by Dong Zhiming and Tang in 1984. To date, only two partial skeletons have been discovered. Neither had an articulated skull, although one skull has been discovered that has been attributed to the genus."Datousaurus."

Shaximiao Formation
The Shaximiao Formation () is a Middle Jurassic, Middle to Late Jurassic aged geological formation in Sichuan, China, most notable for the wealth of dinosaurs fossils that have been excavated from its strata. The Shaximiao Formation is exposed in and around the small township of Dashanpu (), situated seven kilometres north-east from Sichuan's third largest city, Zigong, in the Da'an District, Zigong, Da'an District. Geology The Shaximiao Formation includes two distinct subunits: The upper and lower Shaximiao Formations (), although they are commonly referred to as one, simply being called the "Shaximiao Formation". The upper Shaximiao Formation is also known as the Shangshaximiao Formation, and the lower Shaximiao Formation is also known as the Xiashaximiao Formation, which are direct Transliteration, transliterations of the Chinese names. Both subunits primarily consist of purple-red mudstones, with variable sand inclusion. and siltstones with interbedded sandstones. Dinosau ...

Mamenchisaurids
Mamenchisauridae is a family of sauropod dinosaurs belonging to Eusauropoda known from the Jurassic and Early Cretaceous of Asia and Africa. Some members of the group reached gigantic sizes, amongst the largest of all sauropods. Classification The family Mamenchisauridae was first erected by Chinese paleontologists Yang Zhongjian ("C.C. Young") and Zhao Xijin in 1972, in a paper describing '' Mamenchisaurus hochuanensis''.Young, C.C. and Zhao, X. (1972). "''Mamenchisaurus hochuanensis sp. nov.''". ''Institute of Vertebrate Palaeontology and Palaeoanthropology Monographs'' Series A 8: 1-30. The most complete cladogram of Mamenchisauridae is presented by Moore ''et al.'', 2020, which includes several named species. Notably, some iterations of their analysis recover ''Euhelopus'' and kin, usually considered somphospondylians, as relatives of mamenchisaurids, mirroring earlier conceptions about the family.

Huayangosaurus
''Huayangosaurus'' is a genus of stegosaurian dinosaur from the Middle Jurassic of China. The name derives from "Huayang" (華陽), an alternate name for Sichuan (the province where it was discovered), and "saurus", meaning "lizard". It lived during the Bathonian to Callovian stages, around 165 million years ago, some 20 million years before its famous relative, ''Stegosaurus'' appeared in North America. At only approximately long, it was also much smaller than its famous cousin. Found in the Lower Shaximiao Formation, ''Huayangosaurus'' shared the local Middle Jurassic landscape with the sauropods ''Shunosaurus'', '' Datousaurus'', ''Omeisaurus'' and '' Protognathosaurus'', the ornithopod '' Xiaosaurus'' and the carnivorous ''Gasosaurus''. Description Like other stegosaurians, ''Huayangosaurus'' was a quadrupedal herbivore with a small skull and a spiked tail. Like its more famous relative, ''Stegosaurus'', ''Huayangosaurus'' bore the distinctive double row of plates tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shunosaurus
''Shunosaurus'', meaning "shu lizard", is a genus of sauropod dinosaur from Late Jurassic ( Oxfordian) beds in Sichuan Province in China, approximately 159±2 million years ago. The name derives from "Shu", an ancient name for the Sichuan province. Discovery and species The first fossil of ''Shunosaurus'' was discovered in 1977 by a group of students, practising paleontological excavation at a road bank. The type species, ''Shunosaurus lii'', was described and named by Dong Zhiming, Zhou Shiwu and Zhang Yihong in 1983. The generic name derives from "Shu", an ancient name for Sichuan. The specific name honours hydrologist Li Bing, the governor of Sichuan in the third century BC. The holotype, IVPP V.9065, was collected from the Lower Xiashaximiao Formation near Dashanpu, Zigong. It consists of a partial skeleton. Later about twenty more major specimens were discovered, including several complete or near-complete skeletons, skulls and juveniles, making ''Shunosaurus'' on ...

Omeisaurus
''Omeisaurus'' (meaning "Omei lizard") is a genus of sauropod dinosaur from the Middle Jurassic Period (Bathonian-Callovian stage) of what is now China. Its name comes from Mount Emei, where it was discovered in the lower Shaximiao Formation of Sichuan Province. Like most sauropods, ''Omeisaurus'' was herbivorous and large. The largest species, ''O. tianfuensis'', measured long, and weighed . Other species were much smaller, as the type species ''O. junghsiensis'' reached a size of in length and in body mass, and ''O. maoianus'' reached a size of and . Discovery and species Initial discovery and ''O. changshouensis'' The initial discovery of ''Omeisaurus'' was in 1936 when Charles Lewis Camp and Yang Zhongjian collected a partial skeleton from strata of the Shaximiao Formation in Szechuan, China.Young, C.

Middle Jurassic
The Middle Jurassic is the second epoch of the Jurassic Period. It lasted from about 174.1 to 163.5 million years ago. Fossils of land-dwelling animals, such as dinosaurs, from the Middle Jurassic are relatively rare, but geological formations containing land animal fossils include the Forest Marble Formation in England, the Kilmaluag Formation in Scotland,British Geological Survey. 2011Stratigraphic framework for the Middle Jurassic strata of Great Britain and the adjoining continental shelf: research report RR/11/06 British Geological Survey, Keyworth, Nottingham. the Daohugou Beds in China, the Itat Formation in Russia, and the Isalo III Formation of western Madagascar. Paleogeography During the Middle Jurassic Epoch, Pangaea began to separate into Laurasia and Gondwana, and the Atlantic Ocean formed. Eastern Laurasia was tectonically active as the Cimmerian plate continued to collide with Laurasia's southern coast, completely closing the Paleo-Tethys Ocean. A subduction zone ...

Xiaosaurus
''Xiaosaurus'' ("dawn lizard", ), is a genus of small herbivorous dinosaur from the middle Jurassic, approximately 169 to 163.5 mya. ''Xiaosaurus'' lived in what is now the Sichuan Basin of China. Discovery and naming In 1979 and 1980, two specimens were discovered of a small herbivorous dinosaur during excavations near Dashanpu in Sichuan. In 1983 Dong Zhiming and Tang Zilu named the fossils under the type species ''Xiaosaurus dashanpensis''. The generic name is derived from Chinese ''xiáo'', 曉, "dawn", a reference to the age of the fossil. The specific name refers to Danshanpu. The holotype, IVPP V6730A, was found in the lower Xiashaximiao Formation of which the age is uncertain: both the Bajocian and the Bathonian–Callovian have been proposed. It consists of a partial skeleton including a jaw fragment with a single tooth, two cervical vertebrae, four caudal vertebrae, a humerus, a partial left femur and a complete right hindlimb.

Fossil Taxa Described In 1984
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the absol ...

Diplodocid
Diplodocids, or members of the family Diplodocidae ("double beams"), are a group of sauropod dinosaurs. The family includes some of the longest creatures ever to walk the Earth, including ''Diplodocus'' and ''Supersaurus'', some of which may have reached lengths of up to . Description Diplodocids were generally large animals, even by sauropod standards. Thanks to their long necks and tails, diplodocids were among the longest sauropods, with some species such as ''Supersaurus vivianae'' and ''Diplodocus hallorum'' estimated to have reached lengths of or more. The heaviest diplodocids, such as ''Supersaurus'' and ''Apatosaurus'', may have weighed close to 40 tonnes. However, not all diplodocids were so large; the South American species ''Leinkupal laticauda'' was one of the smallest diplodocids, with an estimated length of only . Their heads, like those of other sauropods, were tiny with the nasal openings on the top of the head (though in life the nostrils themselves would have ...

Zigong Dinosaur Museum Datousaurus
Zigong (, ), formed by the merger of the two former towns of Ziliujing (Tzuliuching, literally "self-flow well") and Gongjing (Kungching, literally "offering well"), is a prefecture-level city in Sichuan, southwestern China. Demographics According to the 2020 Chinese census, the prefecture-level city of Zigong has a population of 2,489,256 inhabitants, less than its population in 2010 (the average annual population growth for the period 2010–2020 was of -0.73%). However, the built-up (''or metro'') area, consisting of the 4 urban districts, grew, with 1,297,695 inhabitants (1,262,064 in 2010). History The area of Zigong has a long history in ancient China - with the invention and development of "Percussion Drilling rig" being one of the city's accomplishments. There are essentially two cities - that of the old and the new. The city was reached by rail in the 1950s. Several four-lane highways reach the city from other cities in the Sichuan province. The new city of Zigong has b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gasosaurus
''Gasosaurus'' () is a genus of tetanuran theropod that lived approximately 171.6 to 161.2 million years ago during the middle of the Jurassic Period. The name "''Gasosaurus''" is derived from the English "''gasoline''" and the Greek () ("lizard / generic reptile"). Only one species is currently recognised, ''G. constructus'', from which the specific name honours the gasoline company that found the Dashanpu fossil quarry in Sichuan Province, China, now named as the Lower Shaximiao Formation. Discovery and naming The first and to date only fossils, albeit postcranial (missing the skull), were recovered in 1985 during the construction of a gas facility, which explains the dinosaur's unusual name. It consists of laterally compressed teeth, 4 cervical, 7 dorsal, 5 sacral, and 7 caudal vertebrae, both humeri, and highly abraded and reconstructed pelvic and hind limb material that includes the left ilium, left ischium, left pubis, left femur, left tibia and left fibula.
