| 摘 要： | 颗石藻作为一种超微远洋浮游生物,出现于侏罗纪里阿斯世(Lias),繁盛于晚白垩世至第三纪。最近又有所进展。哈克(Hag,1981)面告,最老的颗石藻出现于石炭纪和二叠纪。本文所报道之颗石藻发现于晚泥盆世,是截至目前为止最老的颗石藻化石。 颗石藻演化迅速,分布广泛,形态特征明显,而且数量众多,对划分对比海相地层有一定的意义。本文只对研究区所采标本的颗石藻进行鉴定、描述和分类。

| Abstract: | The fossil coccoliths described here are found in the Upper Devonian in Hunan, Guangdong, and Guangsi Provinces. Five genera(among them there is one new genus)and seven new species of coccoliths and discoasters have been identified. The new genus and species are listed as follows: Macropororatadiscoaster gen. nov., including M. pentagram sp. nov., M. Hexagonal sp. nov.; Discolithus microlivaceous sp. nov., Discolithus fankouensis sp. nov., Tetralithus guangdongensis sp. nov., Braarudosphaera pororata sp. nov., and Lithastrinus bicircellatus sp. nov. These forms can be regarded as the oldest fossil coccolithes of all coccolithes that have been hitherto discovered. |
