Shidaisaurus in Yunnan

Shidaisaurus is a genus of metriacanthosaurid dinosaur. Its fossil was found in early Middle Jurassic-age rocks of the Upper Lufeng Formation in Yunnan, China. It is known from a partial skeleton, holotype DML-LCA 9701-IV, found at the bottom of an assemblage of nine dinosaur individuals, lacking most of the tail vertebrae, ribs, pectoral girdle, and limb bones. Shidaisaurus was described in 2009 by Wu and colleagues. The type species is S. jinae. Generic name and specific name in combination refer to the Jin-Shidai (“Golden Age”) Company that exploits the Jurassic World Park near the site.

This theropod was about 6 metres (20 ft) long and it weighed around 700 kilograms (1,500 lb).
