Abstract: The specimen described herein represents a new genus and species Jiangshanosaurus lixianensis of sauropod referable to the Titanosauridae. The specimen was collected by Wei Feng, Wu Wei2Tang and Kang Xi2Min in Jiangshan, Zhejiang allegedly from the lower part of Jinhua Formation in Albian (105Ma) horizon. The preserved part is fairly complete. Compared to the sauropod skeletons in China and other nations from Late Jurassic and Cretaceous, the diagnosis of scapulocoracoid and vertebrae of the new genus is most similar to those of Titanosauridae, especially Alamosaurus. The new fossil is described as the Titanosauridae for the first time in China, and provides new material for studying the evolution and distribution of Cretaceous Sauropoda, Titanosauridae in China.

摘要： 记述的巨龙科Titanosauridae 一新属种——礼贤江山龙( Jiangshanosaurus lixianensis gen. et sp. nov. ) 产自浙江江山的金华组下部,地质时代为早白垩世晚期的Albian 期。化石保存了部分头后骨骼,经过与晚侏罗世至晚白垩世蜥脚类化石的对比表明,新属的尾椎特征与巨龙科较为相似,肩胛骨、乌喙骨与巨龙科中的阿拉蒙龙属( Alamosaurus) 最为接近,但新属的前部尾椎较大,前凹后突的程度较不明显。新属种保存的背椎和中部尾椎的部分特征与我国晚侏罗世马门
