| 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。

| 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:sim- ply-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 di- versity within this sauropod clade in the Cretaceous of Asia. |
