摘要
着重描述湖南邵东保和堂柳东早二叠世早期栖霞组底部首次发现的史塔夫 (Staffella)类动物群 ,共 5属 2 0种 ,这五属分别是史塔夫亚科的 Staffella,Pseudoendothyra,Nankinella和卡勒亚科的 Sphaerulina,Pisolina.该类动物群笔者曾命名为 Pseudoendothyra jazvensis带 .这一发现不仅填补了湘东南栖霞组生物地层学研究的空白 ,而且对我国南方石炭。
The Staffela Fauna discovered and described in this paper was collected by Guo Zhi yang in 1984 from the lowest part of Chihsia Formation in Liudong Section of Baohetang,Shaodong County,Hunan Province.These fusulinids comprise 20 species belonging to 5 genera which belong to Staffellinae,khlerininae, namely, Pseudoendothyra jazvensis (Grozdilova et Lebedeva), P.timanica Rauser,P.bradyi Moeller, Nankinella obesa Wang et Zhou, N.lata Yang, N.compacta Sheng, N.yanyuanica Zhang, N . cf . mianzhuensis Yang, N.subrhomboides Rouser, N .sp., Staffella volieosis Chen et Wang, S.pseudosphaeroidea Sheng, S.rabanalensis Van Ginkel, S.discoides Liu,Dong et Xiao belong to staffellinae; Pisolina subsphaerica Sheng, P .sp., Sphaerulina crassispira Lee, S.weiningensis Liu,Xiao et Dong, S.hunanica Liu and S .sp.belong to Khlerininae. This fauna was named the Pseudoendothyra jarvensis Zone by the author in 1998. The discovey of this fauna not only fills the gaps of the Chihsia Formation biostratigraphy research in Southeastern Hunan,but also provides new basis for study of the middle and below Permain biostratigrahpy division in South China.
