Jiangshanosaurus is a genus of sauropod dinosaur . She lived at the time of the late Lower Cretaceous ( Albium ) in what is now China . The name refers to the city of Jiangshan (江山 市) in the Chinese province of Zhejiang .
This genus was in 2001 with the single species, jiangshanosaurus lixianensis from a Chinese paleontologist team to Tang Feng described . So far, a fragmentary skeleton is known that includes some vertebrae, the shoulder girdle, parts of the pelvis and fragments of a femur and originates from the lower layers of the Jinhua Formation in Zhenjiang , China .
features
Jiangshanosaurus can be distinguished from related genera by a large proximal extension of the shoulder blade (scapula), through which the shoulder blade appears P-shaped when viewed from the side. Furthermore, the opening (foramen) of the cavernous bone (coracoid) was positioned in the center of this bone.
Systematics
Jiangshanosaurus is considered a representative of the Titanosauria. Upchurch and colleagues (2004) note that the anterior caudal vertebrae were procoel (concave on the front), which indicates that they belong to the Lithostrotia (= Titanosauridae). Jiangshanosaurus is the first titanosaur to be discovered in China.
