Mamenchisaurus is a sauropod dinosaur genus including several species, known for their remarkably long necks which made up half the total body length. It is known from numerous species which ranged in time from 160 to 145 million years ago, from the Oxfordian age of late Jurassic Period in China. The largest species may have reached 35 m (115 ft) in length and possibly weighed 50 to 75 tons.
Bellusaurus was a small short-necked sauropod dinosaur from the Middle Jurassic which measured about 4.8 metres (16 ft) long. Its fossils were found in Shishugou Formation rocks in the northeastern Junggar Basin in China.
Chiayusaurus was a genus of sauropod dinosaur known from teeth found in Asia. Two species have been named for this obscure genus. It was originally named as Chiayüsaurus, but the ICZN does not permit special characters, so it has become Chiayusaurus. The old name can still be seen in older sources, though.
Hudiesaurus is a herbivorous sauropod genus of dinosaur from China. The fossil remains of Hudiesaurus were in 1993 found by a Chinese-Japanese expedition near Qiketai in Shanshan, Xinjiang province. The type species, Hudiesaurus sinojapanorum, was named and described by Dong Zhiming in 1997. The generic name is derived from Mandarin hudie, "butterfly" and refers to a flat butterfly-shaped process on the front base of the vertebral spine. The specific name refers to the members of the expedition but can also be read as "central part" in Chinese, a pun on the Japanese Chunichi Shinbun press group, which financed the research.
Klamelisaurus is a genus of herbivorous sauropod dinosaur from the Middle Jurassic of China.
Camarasauridae is a family of neosauropod dinosaurs within the clade Macronaria, the sister group to Titanosauriformes. Among sauropods, camarasaurids are small to medium-sized, with relatively short necks. They are visually identifiable by a short skull with large nares, and broad, spatulate teeth filling a thick jaw. Based on cervical vertebrae and cervical rib biomechanics, camarasaurids most likely moved their necks in a vertical, rather than horizontal, sweeping motion, in contrast to most diplodocids. Cladistically, they are defined to be all sauropods more closely related to Camarasaurus supremus than to Saltasaurus loricatus.
The Shishugou Formation is a geological formation in Xinjiang, China.
The Kalaza Formation is a geological formation in Xinjiang, China whose strata date back to the Late Jurassic. There is some confusion with the stratigraphy of this unit, as the term is used for sediments of equivalent age in both the Junggar Basin and the Turpan Basin. Dinosaur remains are among the fossils that have been recovered from formation
The Kirkwood Formation is a geological formation found in the Eastern and Western Cape provinces in South Africa. It is one of the four formations found within the Uitenhage Group of the Algoa Basin – its type locality – and in the neighbouring Gamtoos Basin. Outcrops of the Kirkwood are also found along the Worcester-Pletmos, Herbertsdale-Riversdale, Heidelberg-Mossel Bay, and Oudtshoorn-Gamtoos basin lines. At these basins the Kirkwood Formation underlies the Buffelskloof Formation and not the Sundays River Formation.
Gobiops is an extinct genus of temnospondyl from the Jurassic of Mongolia, China, and possibly Kyrgyzstan. The genus is represented by a single species, Gobiops desertus. It was named in 1991 from the Late Jurassic Shar Teeg Beds of Mongolia. Additional material was described in 2005 from the Middle Jurassic Toutunhe Formation in the Junggar Basin of China. Gobiops belongs to the family Brachyopidae. The poorly known genus Ferganobatrachus, named in 1990 from Shar Teeg, is probably synonymous with Gobiops.
The Qigu Formation is a Late Jurassic (Oxfordian) geologic formation in the Southern Junggar Basin in China. Indeterminate Dinosaur remains are among the fossils that have been recovered from the formation, including theropod teeth and a fibula. a stegosaur dorsal vertebra and a Eusauropod tooth. Xinjiangtitan was erroneously thought to be from this formation, but it is actually from the older Qiketai Formation, which is in a different basin. The term "Qigu Formation" is also used to sediments of equivalent age in the Turpan Basin, but this might better be treated as a separate formation. It is laterally equivalent to the Shishugou Formation. The remains of indeterminate rhamphorhynchid pterosaurs have been recovered from the formation.
The Toutunhe Formation is a Middle Jurassic geological formation in China. Dinosaur remains diagnostic to the genus level are among the fossils that have been recovered from the formation. The lower portion of the formation consists of grey to reddish mudstone with medium to coarse grained cross bedded sandstone, while the upper portion consists primarily of brown-red-purple mudstone, interbedded with fine to medium grained laminated sandstone.
Sineleutherus is an extinct genus of euharamiyids which existed in Asia during the Jurassic period. The type species is Sineleutherus uyguricus, which was described by Thomas Martin, Alexander O. Averianov and Hans-Ulrich Pfretzschner in 2010; it lived in what is now China during the late Jurassic Qigu Formation. A second species, Sineleutherus issedonicus, was described by A. O. Averianov, A. V. Lopatin and S. A. Krasnolutskii in 2011. It lived in what is now Sharypovsky District during the middle Jurassic ; its fossils were collected from the upper part of the Itat Formation. However, this is now believed to represent several euharamiyid taxa not closey related to Sineleutherus.
The Shishugou Formation dinosaur traps also known as death pits or death traps are found in the Shishugou Formation, located in the Junggar Basin within Xinjiang Province of northwestern China. They are a rich source of Jurassic Period dinosaur fossils, many of which were new species to palaeontology.
Aorun (pron.:"AW-roon") is an extinct genus of carnivorous theropod dinosaur first discovered in 2006, with its scientific description published in 2013. It is one of the oldest known coelurosaurian dinosaurs and is estimated to have lived ~161.6 million years ago during the Late Jurassic Period. It is the fifth theropod discovered from Wucaiwan.
Xinjiangtitan is an extinct genus of mamenchisaurid sauropod known from the Middle Jurassic Qiketai Formation in Piqan County of Xinjiang, northwestern China. Estimates of body length for the holotype are approximately 30–32 m (98–105 ft) in length, making Xinjiangtitan one of the longest sauropods known. In 2016 Gregory S. Paul gave a length of 30 meters and a weight of 40 tonnes.
Tegotherium is an extinct mammal from the Late Jurassic of East Asia. The type species T. gubini is known from the Shar Teeg Beds of Mongoliaand an indeterminate species is also known from the Late Jurassic Qigu Formation of China. It belongs to the clade Docodonta.
The Cañadón Calcáreo Formation is a Oxfordian to Kimmeridgian-aged geologic formation, from the Cañadón Asfalto Basin in Chubut Province, Argentina, a rift basin that started forming since the earliest Jurassic. It was formerly thought to date into the Cretaceous, but the age has been revised with Uranium Lead dating as likely being solely Late Jurassic in age.
Fushanosaurus is a genus of basal titanosauriform dinosaur from the Shishugou Formation from Xinjiang Province in China. The type and only species is Fushanosaurus qitaiensis. It is solely known from the holotype specimen, which consists of a complete right femur. Using "Huanghetitan" ruyangensis and Daxiatitan as a basis, Fushanosaurus was estimated to have been approximately 30 metres (98 ft) long. It was published in the journal Global Geology.
The Xintiangou Formation is a geological formation in China. Part of the stratigraphy of the Sichuan Basin, it is of an uncertain Middle Jurassic age, with preliminary U-Pb estimates giving an age range of 180-170 ma. It predominantly consists of interbedded mudstone and sandstone, with subordinate shelly limestone. The dinosaur Sanxiasaurus and indeterminate sauropods are known from the formation. Theropod and ornithopod tracks have also been reported from the formation.
