| 摘 要： | 本文描述的叶肢介化石是采自辽东中生代苏子河盆地的小岭组、梨树沟组和聂尔库组。小岭组产Eosestheria(Allestheria);梨树沟组产Yanjiestheria;聂尔库组产Orthestheria,Orthestheriopsis。Yanjiestheria,Neodiestheria。梨树沟组、聂尔库组所产化石为典型的延吉叶肢介群分子,属旱白垩世当无疑议。小岭组的时代从伴生的其它门类化石看亦归属早白垩世为宜。苏子河盆地所产叶肢介为延吉叶肢介群,故梨树沟组、聂尔库组与辽西九佛堂组和阜新组不能对比,这是因为辽西九佛堂组所产叶肢介为东方叶肢介群,其层位应在延吉叶肢介群之下。

| Abstract: | The Conchostraca has been described, that is collected from Xiaoling Formation Lishugou Formation and Nieerku Formation of Mesozoic in the Suzihe Basin of the eastern Liaoning province in the paper. Xiaoling Formation had Eosestheria (Allesiheria), considered to be Early Cretaceous. Lishugou Formation contained Yanjiestheria. Nieerku Formation contained Orthestheria, Orthestheriopsis, Yanjiestheria, and Neodiestheria. The fossils occured in Lishugou and Nieerku Formation are typical elements of the Yanjiestheria fauna. They are undoutedly Early Cretaceous.Lishugou and Nieerku Formation cannot correlate with Jiufotang Formation and Fuxin Formation. The latter has an old fauna i.e. Eosestheria. |
