摘　　要：山东聊城地区隐伏的晚古生代含煤地层发育,其中晚石炭—早二叠世太原组灰岩中富含类化石。由三灰、七灰、十灰共鉴定出化石11属45种,自上而下可建立1个类组合带(Pseudoschw agerina带),2个类组合亚带(Triticites paramontiparus亚带;Pseudofusulina firma-Rugosofusulina complicata亚带),该地区所产类组合与华北其他地区及国外相关组合具可比性,Pseudoschw agerina带的时代为早二叠世早期。Late Paleozoic hidden coal - bearing strata developed well in Liaocheng area of Shandong province, and fusulinid fossils developed well in limestones in late Carboniferous and early Permian Taiyuan formation. 45 species in 11 genera of fusulinid can be determined according to limestones in the third, seventh and tenth strata. From upper to lower part, 1 fusulinid zone （ Pseudoschwagerina zone） and two subzones （ Triticites paramontiparus subzone ; Pseudofusulinafirma -Rugosofusulina complicata subzone） can be established. Compared with those in nearby regions and some other areas in north China, the geological age of Pseudoschwagerina zone in this area should be in early Permain.
