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(Qingxiu- saurus 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。
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 ）. Th titanosaurian taxa from Asia, indicates a versity within this sauropod clade in the highly e new form, as well as other recently recovered modified postcranial morphology and large diversity within this sauropld clade in the Cretaceous of Asia.
