| 摘 要： | 异珊瑚化石始发现于早泥盆世 ,早石炭世为鼎盛时期 ,至早二叠世末全部绝灭。本研究将异珊瑚划分为 4个化石组合 ,并对异珊瑚的起源、分布及迁移规律及生态环境等进行了讨论。化石组合由老至新分别为 :早泥盆世 Tetraphyllia组合 ;晚泥盆世 Oligophylloides-H eterophyllia组合 ;早石炭世 Pentaphyllia-H exaphyllia-Radiciphyllia 组合 ;早二叠世 Dichophyllia-H eterophyllia-H exaphylloides组合。并指出异珊瑚属于热带—亚热带至暖温带的生物类群 ,起源中心可能为中国华南板块

| Abstract: | The earliest Heterocorals have been found in Lower Devonian at Wenshan district,Yunnan of China.The Heterocorals got their climax of evolution during Early Carboniferous,and extincted after Early Permian.There are 4 fossil assemblages divided.The authors discuss the characteristic of every fossil assemblage,the patterns of distribution and immigration,and the ecologic environments.The fossil assemblage is as follow: Tetraphyllia Assemblage of Early Devonian; Oligophylloides Heterophyllia Assemblage of Late Devonian; Pentaphyllia Hexaphyllia Radiciphyllia Assemblage of Early Carboniferous; Dichophyllia Heterophyllia Hexaphylloides Assemblage of Early Permian.The authors point out that the South China Plate may be the deriving center of Heterocorallia and the Heterocoral is one of tropic subtropic to warm temperate zone biotic community. |
