Mamenchisauridae

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

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.

Mamenchisauridae is a family of sauropod dinosaurs belonging to the Eusauropoda known from the Jurassic and Early Cretaceous of Asia and Africa. Mamenchisaurids are characterized by their proportionately extremely long necks. Some members of the group reached gigantic sizes, amongst the largest of all sauropods.

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.

Klamelisaurus (meaning "Kelameili Mountains lizard") is a genus of herbivorous sauropod dinosaur from the Middle Jurassic Shishugou Formation of China. The type species is Klamelisaurus gobiensis, which was named by Zhao Xijin in 1993, based on a partial skeleton discovered in 1982 near the abandoned town of Jiangjunmiao. Zhao described Klamelisaurus as the only member of a new subfamily, Klamelisaurinae, among the now-defunct primitive sauropod order Bothrosauropodoidea. Since Zhao's description, Klamelisaurus received limited attention from researchers until Andrew Moore and colleagues redes

Chuanjiesaurus is a genus of sauropod dinosaurs from the middle Jurassic Period. They lived in what is now China. The type species, Chuanjiesaurus anaensis, was first described by Fang, Pang, Lü, Zhang, Pan, Wang, Li and Cheng in 2000. Fossils of the species were found in the village of Chuanjie, Lufeng County, Yunnan Province, (in Chuanjie Formation deposits) and are named after the location where the fossils were discovered. Holtz gave a length of 25 meters (82 ft). left|thumb|Size comparison thumb|Life restoration with a human for scale

Tonganosaurus (named for the town of Tong'an, Sichuan where it was found) is a genus of mamenchisaurid sauropod dinosaur, similar to Omeisaurus. It is known from one specimen consisting of twenty vertebrae, a front limb and pectoral girdle, and a complete hind limb with partial hip. It was discovered in the Yimen Formation, China. The horizon of the specimen and the age of the Yimen Formation is controversial. The formation has been divided into three levels, and Tonganosaurus appears to be of late Early Jurassic (Pliensbachian) in age. Tonganosaurus is the oldest known member of the mamenchis

Eomamenchisaurus (meaning "dawn Mamenchisaurus") is a genus of mamenchisaurid sauropod dinosaur from the Middle Jurassic Zhanghe Formation of Yuanmou, Yunnan, China. The type species is E. yuanmouensis, described by Lü Junchang and colleagues in 2008.

Yuanmousaurus ("Yuanmou lizard") was a sauropod dinosaur from the Middle Jurassic period of China. It is known from incomplete remains, recovered in 2000 from the Zhanghe Formation in Yuanmou County in Yunnan Province. Yuanmousaurus was a relatively large sauropod and may have reached about 17 meters (56 ft) in length. It was a basal member of the Sauropoda, but its exact systematic position is unclear. A recent study placed Yuanmousaurus within the family Mamenchisauridae. It may be a dubious genus. The only and type species was Yuanmousaurus jiangyiensis.

Analong is an extinct genus of mamenchisaurid sauropod from the Chuanjie Formation in Yunnan, China. The type and only species is Analong chuanjieensis. ==Discovery and naming== The fossils of Analong has a relatively convoluted history. The skeletons of two giant sauropods were discovered in 1995 by Tao Wang, who was working with the Lufeng Dinosaur Museum. The fossils were found in the village of A'na and the town of Chuanjie in the Lufeng County of Yunnan. The local villagers built a small shelter around the fossils because they could not be immediately excavated. They remained in situ for

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.

Anhuilong (meaning "Anhui dragon") is a genus of mamenchisaurid dinosaur known from the Hongqin Formation of Anhui province, China. The genus contains a single species, Anhuilong diboensis.

Xinjiangtitan () is an extinct genus of mamenchisaurid sauropod that lived during the Middle Jurassic of what is now Xinjiang, northwestern China. Its type and only species is Xinjiangtitan shanshanesis (), known from a single incomplete skeleton recovered from the Qiketai Formation. The holotype preserves one of the most complete vertebral columns of any sauropod found in Asia, and has the longest complete neck known for any animal.

Hudiesaurus (meaning "butterfly lizard") is an extinct genus of mamenchisaurid sauropod dinosaur that lived in present-day China during the Late Jurassic period. It was described by Chinese paleontologist Dong Zhiming in 1997. The genus contains a single species, Hudiesaurus sinojapanorum, named based on a single vertebra. However, he also assigned teeth and limb bones from a nearby locality to H. sinojapanorum. These fossils were unearthed by the Sino-Japanese Silk Road Expedition near Qiketai in Shanshan, Xinjiang province in rock layers coming from the Kalaza Formation. This formation dates

Qijianglong is a genus of herbivorous mamenchisaurid sauropod dinosaurs. It is known from the Suining Formation of China, which is of a debated age (reported as Late Jurassic or Early Cretaceous using different methods). The genus contains a single species, Qijianglong guokr, known from a partial skeleton including cranial bones, most of the neck and tail, and other associated elements.

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.

Wamweracaudia is a large herbivorous sauropod dinosaur from the Late Jurassic (155-145 million years ago) Tendaguru Formation of Tanzania, Africa.

Jingiella is an extinct genus of mamenchisaurid sauropod dinosaur from the Late Jurassic Dongxing Formation of Guangxi, China. The genus contains a single species, J. dongxingensis, known from vertebrae and limb bones. The original description of Jingiella referred to it using the name "Jingia" which was preoccupied by a moth genus named in 1983, and an amendment was published shortly thereafter, establishing Jingiella as the new replacement name.
