摘　　要：共描述皱纹珊瑚８属１２种，其中新种７个。通过珊瑚化石组合分析，本区珊瑚群性质完全属于中国南方型的特点。区内缺失Ｃｙｓｔｏｐｈｒｅｎｔｉｓ带，泥盆系与石炭系在该区内为假整合接触关系。Ｙｕａｎｏｐｈｙｌｌｕｍ带在炎方区发育较好，但缺乏在华南区广泛分布的群体珊瑚类型，反映该区早石炭世的古环境为近岸浅海环境，不利于群体珊瑚的繁育。The paper discribes 12 species (including 7 new species) in 8 genera of Rugosa. It is suggested from the Rugosa assemblages, that there are no Cystophrentis zone fossils in Yanfang region, characteristic of South China. Therefore, the Upper Devonian and Lower Carboniferous is unconformity in the region. Yuanophyllum zone is well developed in the region and 13 species are found. They are Kueichouphyllum sinense Y, K.heishihkuanense Y, K.simplex sp.nov., K.yanfanense sp.nov., Yuanophyllum longiseptatum Y, Lin et al ., Protocarcinophyllum elegantum sp.nov., Dibunophyllum qujingense sp.nov., Axophyllum sortiseptatum sp.nov., A.varium Fan, Axophylloidesyunnanense sp.nov., Zaphriphyllum zhanyiense sp.nov., Solidophyllum sp., Ekvasophyllum yanfangense Lin, among the coral assemblage. Most genera are widely distributied in Huanan, such as: Kueichouphyllum, Yuanophyllum, Dibunophyllum and so on, and there are a few North America genera, such as: Zaphriphyllum , Ekvasophyllum and one endemic genus Solidophyllum . So far, however, no compound coral were found. These facts may indicate that the regional paleo-enveronment is of near shore shallow marine, and such environment is unsuitable to compound coral living.
