| 摘 要： | 本文描述了贵州边阳地区中三叠统拉丁尼克期的六射珊瑚4属6种，其中1个已知种，1个亲近种，2个新种和2个未定种：Pinacophyllum spizzensis(Tornquist)，P．aff．yunnanense Wu，P．bianyangense sp．nov，Retiophyllia bianyangensis sp．nov．，Procydolites sp．，Margarosmilia sp．，丰富了世界中三叠世六射珊瑚研究的资料。迄今全世界缺乏早三叠世珊瑚，研究中三叠世珊瑚，对探讨中生代开始出现的六射珊瑚的发生和系统演化，古生代四射珊瑚与中生代珊瑚之间存在的关系，都有很重要的意义。

| Abstract: | The scleractinian corals were collected by the authors from the Middle Triassic Ladinian Biangyang Formation in the Bianyang area, Guizhou Province, South China, in August, 2003, including 4 genera and 6 species. They are Pinacophyllum spizzensis (Tornquist), P. aff. yunnanense Wu, P. bianyangense sp. nov., Retiophyllia bianyangensis sp. nov., Procyclolites sp. and Margarosmilia sp. Since no early Triassic corals have been found yet, the middle Triassic corals become the key to the relationship and possible linkage among Rogusa, Tabulata and Scleractinia. The corals from Bianyang will throw light on the occurrence and evolution of Scleractinia. |
