| 摘 要： | 本文报道了辽东苏子河盆地中生代各门类化石,其中植物、双壳、腹足各3属3种;叶肢介6属12种(包括3个新种);介形虫7属10种;昆虫2属2种(包括一新属新种);硅化木1属1种,还有鱼类等,新命1新属4个新种。据此将苏子河盆地的小东沟组、小岭组、梨树沟组、聂尔库组和打石沟组的时代归属为早白垩世,并将小东沟组和小岭组与辽西的义县组及安徽的毛坦厂组进行对比;梨树沟组和聂尔库组与辽西的阜新组及安徽大别山区的黑石渡组进行对比。

| Abstract: | In the paper fossils of Mesozoic in Suzihe Basin of eastern Liaoning are reported, among which Flora, Bivalvia, Gastropoda gen. 3 et sp. 3; Conchostraca gen. 6 et sp. 12, including sp. nov.3; Ostracoda gen. 7 sp.10; Inseeta gen. 2 et sp. 2, including gen. nov.1; Silicified wood gen 1 et sp.1 and fish. And gen.1 et sp. 4 are newly named.According to the above, the age of Xiaodonggou Formation, Xiaoling Formation, Lishugou Formation, Nieerku Formation and Dashigou Formation in Suzihe Basin should belong to the early Cretaceous. and the contrasts of Xiaodonggou Formation and Xiaoling Formation with Yixian Formation of western Liaoning and Maotanchang Formauion of Anhui, Lishugou Formation and Nieerku Formation with Fuxin Formation of western Lianning and Heishidu Formation of Dabieshan Region in Anhui are made |
