Abstract: A new titanosaurian taxon, Qingxiusaurus youjiangensis gen. et sp. nov., from the Upper Cretaceous red beds of Nanning City, Guangxi, China is reported. It is represented by several postcranial elements including a cranial caudal neural spine,a pair of sternal plates, and a pair of humeri. The new taxon is diagnosed on the basis of a combination of following features: simply-built cranial caudal neural spine elongated and paddle-shaped and the length ratio between sternal plate and humerus low (about 0.65). The new form, as well as other recently recovered titanosaurian taxa from Asia, indicates a highly modified postcranial morphology and large diversity within this sauropod clade in the Cretaceous of Asia.

摘要： 记述了采自广西南宁市郊晚白垩世地层中一巨龙类恐龙新属种：右江清秀龙(Qingxiusaurus youjiangensis gen. et sp. nov)。新属种正型标本包括以下不关联的头后骨骼：一段较完整的前部尾椎神经棘、左右胸骨板、左右肱骨。它以以下独特特征组合区别于其他巨龙类：前部尾椎神经棘板状结构不发育、相对较高并呈桨状；胸骨与肱骨最大长之比值较低(约0．65)。广西发现的新属种以及近年来报道的巨龙类恐龙材料表明，亚洲巨龙类恐龙的头后骨骼形态变异度高，白垩纪时期这类恐龙曾在亚洲广为分布。
