Jingshanosaurus, meaning “Jingshan lizard”, is a genus of prosauropod dinosaur from the Early Jurassic Period. A nearly complete skeleton, including the skull, was found near the town of Jingshan, Lufeng County, Yunnan Province, China. The name from which this dinosaur derives, Jingshan, means “Golden Hill”.
Jingshanosaurus was first described in 1995. The type species, J. xinwaensis, was formalized by Zhang and yang. Fossil remains of this species had been exhibited in museums for years before it was formally named.
This was one of the very last of the prosauropods, which slowly died out in favor of their larger relatives, the sauropods. Jingshanosaurus was most closely related to Yunnanosaurus, and has occasionally been placed in the Yunnanosauridae family. In fact, Dong Zhiming considered it a possibly large specimen of Yunnanosaurus. If proven true, Jingshanosaurus would be a junior synonym of Yunnanosaurus.
