Abstract��

A new gigantic sauropod dinosaur��Xinjiangtitan shanshanesis gen. et sp. nov�� is reported with preliminary descriptions�� It is well preserved in situ and discovered from the Middle Jurassic Qigu Formtion in Shanshan of Xinjiang for the first time�� Xinjiangtitan ( gen�� nov�� ) is characterized by a ventral keel developed on the penultimated cervical centrum and formed a small semi-circular process under the distal articular facet��last two cervical vertebrae are particularly elongated ( ratio“length of the last two cervical vertebrae / length of femur and tibia”is 0. 63) ��sacricostal yoke excepting the first sacral rib��and extremely robust femur ( ratio“transverse width of the distal end / femur length”is 0. 33) �� Cladistic analysis places Xinjiangtitan as the sister group of Mamenchisaurus�� Xinjiangtitan is definitely a new taxon of mamenchisaurid dinosaur�� However��Xinjiangtitan developed several diplodocid-like characters: prominent ambiens process of pubis��relatively short hind limb and caudomedially developed fourth trochanter on femoral body�� The total body length of Xinjiangtitan is calculated as 30-32 meters��
