Shaximiao Formation

Mamenchisaurus ( , or spelling pronunciation ) is an extinct genus of sauropod dinosaurs known for their remarkably long necks, which made up nearly half the total body length. Numerous species have been assigned to the genus; however, the validity of these assignments has been questioned. Fossils have been found in the Sichuan Basin and Yunnan Province in China. Several species from the Upper Shaximiao Formation, whose geologic age is uncertain, have been described. However, evidence suggests this formation to be no earlier than the Oxfordian stage of the Late Jurassic. M. sinocanadorum dates

Tuojiangosaurus (meaning "Tuo River lizard") is a genus of herbivorous stegosaurian dinosaur from the Late Jurassic Period, recovered from the Upper Shaximiao Formation of what is now Sichuan Province in China.

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 Shunosauru

Agilisaurus (; 'agile lizard') is a genus of ornithischian dinosaur from the Middle Jurassic Period of what is now eastern Asia. The only named species is A. louderbacki, recovered from the Lower Shaximiao Formation of Sichuan, China. It was about in length, in hip height, and in weight. It has leaf-shaped teeth that were well-adapted to its abrasive, plant-based diet. Most surprisingly, the wavy enamel of the teeth of this genus (and all other ornithopods), presumed to make them more resistant to wear, was previously thought to be exclusive to hadrosaurs. This is also the case for Changchunsa

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.

Yangchuanosaurus is an extinct genus of metriacanthosaurid theropod dinosaur that lived in China from the Middle Jurassic to Late Jurassic periods (Bathonian to Tithonian stages), and was similar (although slightly larger) in size and appearance to its North American and European relative, Allosaurus. Yangchuanosaurus hails from the Upper Shaximiao Formation and was the largest predator in a landscape that included the sauropods Mamenchisaurus and Omeisaurus and the stegosaurs Chialingosaurus, Tuojiangosaurus and Chungkingosaurus. This theropod was named after the area in which was discovered,

Abrosaurus (; 'delicate lizard' from the Greek '''''''''' meaning 'delicate' or 'dainty' and '''''' meaning 'lizard') is a genus of macronarian sauropod dinosaur from the Middle Jurassic Period of what is now Asia. It is one of many dinosaurs found at the Dashanpu Quarry in the Sichuan Province of China. Like most sauropods, Abrosaurus was a quadrupedal herbivore. It was rather small for a sauropod, measuring no more than long. Its head was boxy and topped with a tall, bony arch containing the nostrils. The generic name refers to the nature of the skull, with large openings separated by thin,

Omeisaurus (meaning "Omei lizard") is a genus of sauropod dinosaur from the Middle to Late Jurassic Period (Bathonian-Oxfordian stage) of what is now China. Its name comes from Mount Emei, where it was discovered in the lower Shaximiao Formation of Sichuan Province.

Shunosaurus () is a genus of sauropod dinosaur from Late Jurassic (Oxfordian) beds in Sichuan Province in China, from 161 to 157 Million years ago. The name derives from "Shu", an ancient name for the Sichuan province.

Chungkingosaurus (meaning "Chongqing Lizard") is a genus of stegosaurian dinosaur from the Late Jurassic Upper Shaximiao Formation in what is now China. The type species is Chungkingosaurus jiangbeiensis.

Chialingosaurus (meaning "Chialing Lizard") is a genus of herbivorous stegosaurian dinosaur similar to Kentrosaurus from the Upper Shaximiao Formation, Late Jurassic beds in Sichuan Province in China. Its age makes it one of the oldest species of stegosaurs, living about 160 million years ago. Since it was an herbivore, scientists think that Chialingosaurus probably ate ferns and cycads, which were plentiful during the period when Chialingosaurus was alive.

Gigantspinosaurus () is a genus of stegosaurian dinosaur from the Late Jurassic (Oxfordian) Upper Shaximiao Formation of China. The type species is Gigantspinosaurus sichuanensis. It was a moderately sized member of the group, measuring up to in length.

Chuandongocoelurus ( ) is a genus of carnivorous tetanuran theropod dinosaur from the Jurassic of China.

Leshansaurus is a genus of theropod dinosaur from the Late Jurassic Shaximiao Formation of what is now China. It was described in 2009 by a team of Chinese paleontologists. The type species is Leshansaurus qianweiensis. Fossils of Leshansaurus were discovered in strata from the Shangshaximiao Formation, a formation rich in dinosaur fossils. Li et al. referred this taxon to Sinraptoridae – a group of carnosaurian theropods, but it may belong to Megalosauridae instead.

Xuanhanosaurus (meaning "Xuanhan lizard") is a genus of theropod dinosaur that lived during the Middle Jurassic (Bathonian) of the Sichuan Basin, China, around 166 million years ago. This taxon represents one of the various non-coelurosaurian tetanuran taxa found on the Middle Jurassic of the region, uncovered in the Lower Shaximiao Formation. Although it has been known for more than 40 years, this taxon has been the subject of very few studies, although most seem to agree that it is a tetanuran, possibly a basal allosauroid, highlighting the fact that it has a vestigial fourth metacarpal.

Xiaosaurus ("dawn lizard", ), is a genus of small herbivorous ornithischian dinosaur from the middle Jurassic (approximately 170.3 to 163.5 million years ago) of what is now the Sichuan Basin of China.

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) is a sauropod dinosaur from the Middle Jurassic Lower Shaximiao Formation in Sichuan province, China. It shared the local Middle Jurassic landscape with other sauropods such as Shunosaurus, Omeisaurus, and Protognathosaurus, the neornithischian Xiaosaurus, and the early stegosaur Huayangosaurus as well as the carnivorous Gasosaurus.

Yandusaurus is a genus of basal neornithischian dinosaur from the middle Jurassic (Bathonian age, approximately 168 to 162 Ma) of eastern Asia. The type species is Y. hongheensis, described in 1979 from the Lower Shaximiao Formation of Sichuan Province, China.

Daanosaurus (meaning "Da'an lizard" after Da'an district in Zigong, Sichuan) was a genus of sauropod dinosaur which lived during the Late Jurassic (Oxfordian - Tithonian stage, about 163 - 145 mya). It lived in what is now China (Sichuan Province), and was similar to Bellusaurus. Daanosaurus is known only from a partial skeleton of a juvenile, and it has been debated whether the specimen may be a juvenile mamenchisaurid.

Dashanpusaurus (meaning "Dashanpu lizard" after the township it was discovered in) is an extinct genus of sauropod dinosaur that lived during the middle of the Jurassic period. The dinosaur was described in 2005 by Peng Guangzhao, Ye Yong, Gao Yuhui, Shu Chunkang, and Jiang Shan. Its type and only species is Dashanpusaurus dongi, named in honor of the paleontologist Dong Zhiming.

Gongbusaurus is a genus of ornithischian, perhaps ornithopod, dinosaur that lived between about 160 and 157 million years ago, in the Late Jurassic period. A small herbivore, it is very poorly known. Two species have been assigned to it, but as the original name is based on teeth, there is no concrete evidence to connect the two species. Its fossils have been found in China.

Kaijiangosaurus (meaning "Kaijiang lizard") is a genus of carnivorous tetanuran theropod dinosaur from the Middle Jurassic of China. In 1984 He Xinlu named and described the type species Kaijiangosaurus lini. The generic name refers to the River (jiang) Kai. The specific name honours the paleontologist Lin Wenqiu.

Yingshanosaurus (meaning "Yingshan lizard") is an extinct genus of stegosaurian dinosaurs from the Middle Jurassic of what is now Southwestern China. It is known from a partial skeleton discovered in 1983, including back, sacrum, and tail vertebrae, forelimb and hindlimb bones, shoulder and hip bones, and several osteoderms, including plates and a shoulder spine. The genus contains a single species, Yingshanosaurus jichuanensis, named and described in 1994. For some time after its discovery and scientific description, many paleontologists were unaware of the Chinese research published on it an

Hexinlusaurus is a genus of basal ornithischian dinosaur from the Middle Jurassic (Bajocian stage) Lower Shaximiao Formation of what is now China. The type and only species is Hexinlusaurus multidens.

Zigongosaurus (meaning "Zigong lizard") is a genus of sauropod dinosaur from the Middle-Late Jurassic-aged Shaximiao Formation of Zigong, Sichuan, China. Because of incomplete knowledge of Jurassic Chinese sauropods, it has been hard to interpret, with some sources assigning it to Omeisaurus, some to Mamenchisaurus, and some to its own genus.

Protognathosaurus (meaning "early jaw lizard") is a genus of herbivorous sauropod dinosaur from the Middle Jurassic Lower Shaximiao Formation in Sichuan, present-day China.

Tienshanosaurus (meaning "Tienshan lizard") is an extinct genus of sauropod dinosaur from the Late Jurassic of what is now China. Only one species is known, Tienshanosaurus chitaiensis, which was named and described in 1937.
