苏皖北部新元古代海相泥页岩、粉砂岩及燧石中富含微生物化石.其中,通过化学浸解法,从碎屑岩中获得14个形态属种的微生物化石;6个形态属种的蓝细菌化石呈三维立体状态保存在燧石切片中.浸解获得的泥页岩、粉砂岩相微生物化石,在刘老碑组中-上部的主要是片形和球形:Laminarites antiquissimus,Leiosphaeridia pelucida,Spumiosa alara及Asperatopsophosphaera bavlinensis;在九里桥组、贾园组和赵圩组主要为多面形和球形:Monilinema quadratucella及Synsphaeridium sp.;而史家组、金山寨组和沟后组则有丰富的球形、片形、梭形和带形个体:Leiosphaeridia hyperboreica,Trachysphaeridium simplex,Annulum difuminatum,Nucellosphaeridiumasperatum,Tophoporata sp.,Symplassosphaeridium sp.,Macroptycha uniplicata及Taeniatum simplex.该微生物组合可与河北及天津蓟县的新元古界景儿峪组和下马岭组的相对比.虽然上述微生物化石的系统古生物学仍在研究中,但却为我们了解新元古代大冰期前夕近岸海相环境生物圈提供了有关浮游植物的信息.苏皖北部新元古代倪园组及九顶山组的燧石中,保存良好的微生物三维立体化石为丝形和球形蓝细菌遗留物,包括Siphonophycussp.,Eoentophysalis belcherensis,Eozygion grande,Tetraphycus conjionceum,Globophycus rugosum及Caryosphaeroidespristine.该蓝细菌组合可能是底栖的,它们出现在非叠层石的碳酸盐沉积环境.
