| 摘 要： | 描述了贵州金沙岩孔镇长岩沟下寒武统(纽芬兰统一寒武系2统)牛蹄塘组底部黑色页岩中呈碳质薄膜保存的高肌虫化石,共2属1种1相似种和1未定种:朵氏昆明虫Kunmingella douvillei,昆明虫(未定种)Kunmingella sp.和新月形遵义虫相似种Tsunyiella of luna.这些高肌虫化石与最古老的三叶虫Tsunyidiscus(Mianxiiandiscus)共生,其层位可与云南的Abadiella带对比,表明Kunmingella和Tsunyiella的下限层位已下延至筇竹寺阶的底部.本应属于早寒武世高肌虫分布中区的金沙一带却发现了两区的典型分子Kunmingella和中区的Tsunyiella,说明两区与中区间的混生区的范嗣应从长宁-镇雄小区扩大至贵州的金沙和织金一带.贵州寒武系底部大量高肌虫的发现丰富了牛蹄塘生物群的组成,对研究寒武纪早期生物的演化具有一定的意义.

| Abstract: | Some Bradoriida fossils were preserved in the manner of carbonaceous membrane in black shale of the lower part of the Niutitang Formation of the traditional Lower Cambrian(Terreneuvian and Cambrian Series 2)in Zhangyangou Village,Yankong Town,Jinsha County,Guizhou Province.They include two genera,one species,one conformis species and one uncertain species as listed below:Kunmingella douville,Kunmingella sp.and Tsunyiella cf.luna.These bradoriid fossils were found in association with the oldest trilobite Tsu... |
