摘　　要：在湖北郧西县发现寒武纪微古植物共12属28种。它们以刺球藻类大量出现为主要特征,刺球藻约占微古植物组合的60％,球藻类约占35％,其他类型的约占5％。上述微古植物组合特征,在我国云南昆明以及欧洲、北美一些地区的寒武系中可见到,这一组合特征充分显示出寒武纪的特点。Microplants, including 12 genera and 28 species, have been discovered in the Cambrian of Yunxi county, Hubei. The features of the microplant assemblage are as follows: the elements of Acanthomorphida are dominant, accounting for about 60% ; the elements of Sphaerorphida take second place, making up about 35%; other types represent about 5%. The features of the microplant assemblage mentioned above are reported in the Cambrian in Kunming, Yunnan, China , and in some areas of Europe and North America, which fully show the Cambrian features.
