In 2004 a partial semi-articulated specimen from Jiangyi Township in Yuanmou County was described as the new species "Shunosaurus jiangyiensis". It is known from nine cervicals, 15 dorsals, three sacrals, four caudals, both scapulae, the right coracoid and clavicle, the right forelimb lacking the hand, a pubis and ischium and the right hindlimb, found in the upper section of the Middle Jurassic Xiashaximiao Formation. The species was separated from "Shunosaurus lii" based on its unique pectoral girdle, but was described as otherwise very similar to both "Shunosaurus lii" and "Kunmingosaurus".
