摘　　要：对福建沙县富口早二叠世早期地层中类动物群进行系统研究 ,共鉴定类化石 1 0属 2 1种 ,包括 2个新种 .根据类动物群在地层中的分布和垂向变化规律 ,自下而上建立 3个化石带 :(1 )Pseudoschwagerina miharanaensis带 ,(2 )Sphaeroschwagerina sphaerica带和(3)Eoparafasulina pararegularis带 .通过与邻区及我国华南其他地区同期地层的对比和石炭 -二叠系地层界线的讨论 。This paper repors Early Early Permian strata in Fukou of Shaxia, Fujian. By a systematic study of the fusulinid fauna from the strata, 10 genera and 21 species of fusulinid fossils have been found,including 2 new species. According to the geographical distribution and vertical variation of fusulinid fauna in the strata, the fusulinid fauna may be distinguished into 3 zones as following (in ascending order). 1) Pseudoschwagerina miharanaensis zone, 2) Sphaeroschwagerina sphaerica zone and 3) Eoparafusulina pararegularis zone. Compared with those in nearby regions and some other areas in South China, and discussed for Carboniferous Permian boundary, the geological age of the fusulinid fauna in the strata should be Early Early Permian, and the boundary between Carboniferous and Permian in Fukou should be placed at the bottom of Pseudoschwagerina miharanensis zone.
