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.

Dashanpu Quarry
The Shaximiao Formation () is a 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. 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 transliterations of the Chinese names. Both subunits primarily consist of purple-red mudstones, with variable sand inclusion. and siltstones with interbedded sandstones. Dinosaur finds The Shaximiao Formation has produced mainly ...

Sauropod
Sauropoda (), whose members are known as sauropods (; from '' sauro-'' + '' -pod'', 'lizard-footed'), is a clade of saurischian ('lizard-hipped') dinosaurs. Sauropods had very long necks, long tails, small heads (relative to the rest of their body), and four thick, pillar-like legs. They are notable for the enormous sizes attained by some species, and the group includes the largest animals to have ever lived on land. Well-known genera include ''Brachiosaurus'', ''Diplodocus'', ''Apatosaurus'' and ''Brontosaurus''. The oldest known unequivocal sauropod dinosaurs are known from the Early Jurassic. ''Isanosaurus'' and ''Antetonitrus'' were originally described as Triassic sauropods, but their age, and in the case of ''Antetonitrus'' also its sauropod status, were subsequently questioned. Sauropod-like sauropodomorph tracks from the Fleming Fjord Formation (Greenland) might, however, indicate the occurrence of the group in the Late Triassic. By the Late Jurassic (150 million yea ...

Zigong Dinosaur Museum
The Zigong Dinosaur Museum () is located near the city of Zigong, Sichuan, China, in the township of Dashanpu. History The museum sits on top of a large concentration of a diverse dinosaur assemblage from the Shaximiao Formation. The museum claims the largest number of dinosaur fossils in the world and covers 25,000 square meters with a display area of 3,600 square meters. It attracts up to seven million visitors a year. In 1980s, vast quantities of dinosaur fossils were excavated in the Middle Jurassic Shaximiao Formation, 7 km north-east from downtown Zigong, including a dinosaur named after the township, ''Dashanpusaurus''. Because of the unique and articulated (intact) bone remains, Zigong is important to paleontologists and dinosaur enthusiasts. The Zigong Dinosaur Museum was established in 1987, becoming the first museum based almost entirely on dinosaurs in Asia. Mounted specimens include ''Omeisaurus'', ''Gigantspinosaurus'', ''Yangchuanosaurus'', ''Huayangosau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cetiosauridae
Cetiosauridae is a family of sauropod dinosaurs which was first proposed by Richard Lydekker in 1888. While traditionally a wastebasket taxon containing various unrelated species, some recent studies have found that it may represent a natural clade. Alongside ''Cetiosaurus'' from the Middle Jurassic of Britain, other taxa recently assigned to the family include ''Lapparentosaurus'' from the Middle Jurassic of Madagascar, and ''Patagosaurus'' from the late Early-Middle Jurassic of Patagonia, which share autapomorphies with ''Cetiosaurus'' that are not shared by other eusauropods. Additionally, at least one study has suggested that the 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 T ... may represent a sub-group of the cetiosaurids, which would be termed Mamenchisau ...
