| 摘 要： | 目的梳理华南布尔吉斯页岩型软躯体化石生物群的产出层位、生物面貌和沉积环境。方法对10个华南布尔吉斯页岩型软躯体化石生物群进行对比研究。结果除了岩家河生物群之外的9个布尔吉斯页岩型生物群代表了一系列生活在泥砂质基底的、从时空分布上逐渐过渡的具有高度相关性的生物群落。结论布尔吉斯页岩型化石生物群在中晚寒武世应该会有更大规模的分布。

| Abstract: | Aim To combing from the Burgess Shale-type fossil biotas in South China at the sight of horizon,biological composition and sedimentary environment.Methods Ten Burgess Shale-type soft-bodied fossil biotas in South China are investigated by comparing the geological settings,biological composition and their substrates.Results Except for the Yanjiahe biota,the other nine Cambrian Burgess Shale-type soft-bodied fossil biotas in South China represent a series of closely-related biological communities lived in muddy-sandy substrates which show gradually transitions in biological composition in time-space distributions.Conclusion The Burgess Shale-type fossil biota in South China should have a wider distribution during the Middle-Late Cambrian. |
