| 摘 要： | 记述了产自山东诸城上白垩统王氏群中一个较完整的蜥脚类恐龙肱骨(ZJZ-57)。它具有一些进步特征,如肱骨三角胸嵴向远端扩展,肱骨近端外侧1/3处发育隆凸,表明其属于较进步的巨龙类成员。另外,它具有一些独特的鉴定特征组合区别于其他任何巨龙类:近端横向强烈扩展,近端最大宽度与骨干长度之比为0.55;骨干粗壮,粗壮指数为0.39。综合研究表明,ZJZ-57所属个体代表了一种新的巨龙类恐龙:臧家庄诸城巨龙(Zhuchengtitan zangjiazhuangensis gen.et sp.nov.),它可能与Opisthocoelicaudia的亲缘关系较接近。这是山东晚白垩世地层中首次发现的巨龙类恐龙。

| Abstract: | Specimen ZJZ-57, a nearly complete sauropod humerus excavated from the Upper Cretaceous Wangshi Group of Zhucheng area, Shandong Province, is described in this paper. Some derived features, such as a lateral bulge at the proximal onethird position of the lateral margin and a deltopectoral crest markedly expanded distally, indicate that ZJZ-57 represents a member of Titanosauria. However, it differs from all other titanosaurian sauropods in the following combined features:the proximal portion is strongly expanded, reaching 55% of the total length of the bone, and the humerus is a robust bone, with a robustness index (RI) of 0.39. Based on this specimen, the authors erect a new sauropod taxon:Zhuchengtitan zangjiazhuangensis gen. et sp. nov. This new taxon is possibly more closely related to Opisthocoelicaudia than to other known titanosaurian sauropods from Asia. This is the first ti-tanosaurian sauropod reported from the Upper Cretaceous strata of Shandong Province. |
