摘要	We report a new eusauropod dinosaur, Huashanosaurus qini gen. et sp. nov., based on a partial skeleton recovered from a bed in the Lower to Middle Jurassic Wangmen Formation (Fm.) from Huqiu Quarry near Mingjiang River, Ningming County, Guangxi Zhuang Autonomous Region, southern China. The new taxon can be diagnosed by the following autapomorphies: posterior process of the ulna hook-shaped; the cross-section of the proximal part of the ulna crescent-shaped; groove structure present at the posterodistal surface of the fibula. Phylogenetic analysis reveals that H. qini is later-diverging than the Middle Jurassic Shunosaurus. Previous work showed that the Wangmen Fm. is early Early Jurassic in age whereas the new eusauropod discovery indicates that the Wangmen Fm. is probably somewhat younger Early-Middle Jurassic in age. The find increases the diversity of Jurassic eusauropods in China.
