Jingshanosaurus

Jingshanosaurus (meaning "Jingshan lizard") is a genus of sauropodomorph dinosaurs from the early Jurassic period 201.3 million years ago that went extinct 199.3 million years ago in the Hettangian Age.

For the stegosaur of a similar name, see Yingshanosaurus. For the Early Cretaceous–age sauropod, see Jiangshanosaurus.

Its maximum weight was around 4.3 t with an adult femur length of 845 mm.[1] Jingshanosaurus xinwaensis grew to be 5 meters (16.4 ft) long.[2]

History of discovery
Restoration

Its fossils, a nearly complete skeleton including the skull, were found near the town of Jingshan ("Golden Hill"), Lufeng County, Yunnan Province, China, from which the name derives.[3] First described in 1995, the type species is J. xinwaensis, formalized by Zhang and Yang.[4] Fossil remains of Jingshanosaurus had been exhibited in museums several years prior to the formal naming. A complete skeleton and skull of Jingshanosaurus xinwaensis have been found and is considered the last prosauropods to live on earth.[5]

Classification

Jingshanosaurus may have been most closely related to Yunnanosaurus, and has, at times, been included in the Yunnanosauridae. In fact, Dong Zhiming considered Jingshanosaurus possibly a large specimen of Yunnanosaurus. If true, this would make Jingshanosaurus a junior synonym of Yunnanosaurus.
