摘　　要：在建始三道岩泥盆纪写经寺组下部发现PseudozaphrentisdifficileSun等珊瑚化石群 ,并据其组合特征提出原定为晚泥盆世晚期的写经寺组下部的时代应为晚泥盆世早期 ,可与欧洲的弗拉斯阶对比。据珊瑚化石古生态特征探讨了形成环境 ,并对其进行了描述和图示。Reported in this paper are the rugose corals (including Pseudozaphrentis difficile, P.curvata, P.sp., Hunanophrentis sp., Sinodisphyllum sp., Asterobillingsia bowerbanki) occurring in the lower part of Xiejinsi Formation at Sandaoyan of Jianshi, Hubei province. Analysis of geological distribution and range of this corals fauna indicates that coral bearing strata of this formation may be roughly corresponded with the Frasnian stage in age, and belong to the early Late Devonian. Besides, coral palaeoecologyic characters are also discussed with some fossils described and shown in this paper.
