| 摘 要： | 贵州剑河八郎乌溜—曾家崖寒武系第5阶底界潜在的全球层型剖面及点位上下的动物群(三叶虫和无铰纲腕足类)有显著的变化;研究的剖面厚约4.5m,穿过首现点位Oryctocephalus indicus。经逐层化石的采集和深入的研究,证实在寒武系第4阶或寒武系第2统顶部Ovatoryctocara granulata-Bathynotus holopygus带与寒武系第5阶或寒武系第3统底部Oryctocephalus indicus带之间大约有20cm的贫化石间隔区。这一动物群的突变是在均一的岩相中发生的,表明该剖面是建立寒武系第5阶(或第3统)底界的全球层型剖面和点位(GSSP)理想剖面。

| Abstract: | Quarrying across a potential GSSP of the Cambrian Stage 5/Series 3 boundary indicates a significant change in trilobite and inarticulate brachiopod faunas. The quarry spans approximately 4.5 m across the potential boundary,which is the FAD of Oryctocephalus indicus in the Wuliu-Zengjiayan section. Detailed collections show that the faunas of the Ovatoryctocara granulata-Baythyonotus holopygus and the O. indicus zones changed in a 20 cm,relatively barren interval. This faunal turnover does not coincide with ... |
