| 摘 要： | 系统描述了采自贵州省兴义中三叠统竹杆坡组一件较完整的巨胫龙(Macrocnemus)属化石标本,补充和完善了M.fuyuanensis部分头骨及腕骨和跗骨特征。基于当前标本与欧洲的M.bassaniis和中国的M.fuyuanensis的比较,认为当前标本与M.fuyuanensis四肢骨骼大小及比例较为接近,但两者的胫骨与桡骨、尤其第4跖骨和第4掌骨之间的比例不同。鉴于当前标本较少,头骨保存不完整,且当前标本与M.fuyuanensis正模标本的产地相距不远,本文暂将其确定为后者的相似种。

| Abstract: | A new material of Macrocnemus is described on the basis of a complete and well-preserved skeleton from the Middle Triassic Zhuganpo Formation of Wusha,Xingyi,SW Guizhou.The study of the present skeleton further supplement and complete some features of skull,carpals and tarsals of M.fuyuanensis reported by Li et al.（2007）.Compared with M.bassaniis and M.fuyuanensis,this new material is closely resemble to M.fuyuanensis in the shape of most skeletons,but they both also show same differences,especially the ratio of the length of the tibia and radius and the ratio of the length of the forth metatarsal and the forth metacarpals.Due to only rare specimens to be found and that the skull of this new skeleton is not complete,and its locality is close with that of M.fuyuanensis,so it is tentatively regarded as a similar taxon to the Macrocnemus fuyuanensis Li,2007. |
