摘　　要：太子河流域西部竹蜓类动物群，以本溪—牛心台地区为最发育，一般可划分为一个共存延限带，一个组合带，后者又可进一步划分为３个组合亚带。ⅡＦｕｓｕｌｉｎａ－Ｆｕｓｕｌｉｎｅｌａ组合带３Ｆｕｓｕｌｉｎａｃｙｌｉｎｄｒｉｃａ－Ｆ．ｑｕａｓｉｃｙｌｉｎｄｒｉｃａ组合亚带２Ｆｕｓｕｌｉｎｅｌａｐｒｏｖｅｃｔｕ－Ｆｕｓｕｌｉｎａｐｓｅｕｄｏｋｏｎｎｏｉ组合亚带１Ｆｕｓｕｌｉｎａｓｃｈｅｌｗｉｅｎｉ－Ｆ．ｍａｙｉｅｎｓｉｓ组合亚带ⅠＰｒｏｆｕｓｕｌｉｎｅｌａｐａｒｖａ－Ｅｏｓｔａｆｅｌａｓｕｂｓｏｌａｎａ共存延限带Ｐｒｏｆｕｓｕｌｉｎｅｌａｐａｒｖａ系作者等研究辽南竹蜓类并建带的带分子，Ｅｏｓｔｕｆｆｅｌａｓｕｂｓｏｌａｎａ为盛金章教授建立的辽东本溪群下部竹蜓带的带分子，时代为中石炭世早期。Ｆｕｓｕｌｉｎａ－Ｆｕｓｕｌｉｎｅｌａ组合带代表本区及东北南部最发育的竹蜓类动物群。该带属于中石炭世中—晚期，也是太子河流域最大海侵期。以上二个竹蜓类生物带总体应属于Ｍｏｓｃｏｖｉａｎ阶，时代为中石炭世。Fusulinid faunas in the west of Taitzeho valley the most well developed in the area from Benxi to Niuxintai, could be divided into a concurrent range zone and an assemblage zone, the latter was subdivided into 3 assemblage subzones:Ⅱ FusulinaFusulinella assemblage zone3 Fusulina cylindricaF.quasicylidrica assemblage subzone2 Fusulinella provectaFusulina pseudokonnoi assemblage subzone1 Fusulina schellwieniF.mayiensis assemblage subzoneⅠ Profusulinella parvaEostaffella sublolana concurrent range zoneProfusulinella parva was a composition which had been used to study Fusulinid in South Liaoning and to establish the zone; Eostaffella subsolana was a composition of Fusulinid zone in the Lower Benxi Group(established by Pro.Sheng Jinzhang in 1958) in East Liaoning province, which the age was the early stage of MidCarboniferous. FusulinaFusulinella assemblage zone was the most well developed Fusulinid Faunas in the study area and southern Northeast China, which the age was the midlate stage of MidCarboniferous, the largest marine transgression period in Taizeho valley Above Fusulind biozones should belong to Moscovian stage, MidCarboniferous.
