摘　　要：根据珊瑚化石 Phillipsastrea hunanense,Mictophyllum zhuzhouense,Pseudozaphrentis?curvatum,Peneck-iella sp.及 Crassialveolites sp.等确定建始长梁子一带的写经寺组底部属弗拉阶。鄂西写经寺组应属法门阶及部分弗拉阶沉积。Fairly aboundant corals including Pseudozaphrentis? curvatum Sun, Mictophyllum zhuzhouense Jiang, Phillipsastrea hunanense Jiang, Peneckiella sp., and Crassialveolites sp. have been found in the lowermost part of the Hsiehchingsu (Xiejingsi) Formation of Changliangzi area, Jianshi County, West Hubei. These corals are very common in the Shetianchiao (Shetianqiao) Formation, Central Hunan. They indicate a Frasnian age. Accordingly, the age of the Hsiehchingsu Formation may range from Frasnian to Famennian. In addition, some poorly preserved conodonts occur together with these corals. They include Polygnathus cf. brevicarina Klapper & Lane, P. brevilaminus Branson & Mehl, P. brevis Miller & Youngquist, P. germanus germanus Ulrich & Bassler, P. sp., Apatognathus varians klapperi Druce, A. sp., Hindeodella corpulenta Branson & Mehl, H. subtilis Ulrich & Bassler, H. sp., Neoprioniodus alternata (Bassler), and Polylophodonta sp..
