摘　　要：贵州富含早期后生(动)生物群,由老到新为埃迪卡拉系的瓮安生物群、江口庙河生物群,寒武系1统小壳动物群、2统下部牛蹄塘生物群、遵义生物群、中部杷榔动物群、顶部台江生物群及第3统底部凯里生物群。除了小壳动物群及台江生物群外,其他生(动)物群的近期研究均取得了进展。与中国南部的其他系列早期后生生(动)物群,特别是澄江及高家山生物群等形成中国早期后生生物演化链,反映了前寒武纪至寒武纪动物出现至动物骨骼化再至动物主要门类出现再至生物多样、生物生态化的演化过程。The fossil record of the origin and early diversification of the Metazoa is extremely rich in Guizhou Province, five exceptionally-preserved metazoan biotas have been discovered, in order of decreasing age, they are the Weng^n and the Miaohe（Jiangkou） Biotas of the Ediacaran, the Small Shelly Fauna of Cambrian Series 1, the Zunyi Biota of the lower Series 2 of Cambrian, the Balang Fauna of the upper Series 2 of Cambrian, the Taijiang Biota of the top Series 2 of Cambrian and the Kaili Biota of Cambrian Series 3. Except the Small Shelly Fauna and the Taijiang Biota, recently, significant progresses of the research on other biotas have been made. Together with other Biotas of south China, especially the Chengjiang and Gaojiashan Biotas constitute an evolu- tionary chain of early metazoans, which indicates the evolutionary sequence ： the appearance of metazoans - the skeletonization of animals - the appearance of major phyla and classes of animals - the radiation and diversifica- tion of creatures and the complexity of ecological environment.
