摘要
黔中明心寺组Mianxianella-Qingzhenaspis组合带位于Metaredlic-hioides带之下;而在陕南阎王碥组下部,Mianxianella,Qingzhenaspis又与Drepanuroides带的带化石Drepanuroides及Drepanopyge等共生或共产,因此Mianxianella-Qingzhenaspis组合带可和Drepanuroides带对比。本文还描述了Mianxianella-Qingzhenaspis组合带中重要分子Meitanella的一个新种。
Mianxianella---Qingzhenaspis Ass. Z. is located under Metaredlichioides Z. of Minghsingssu Formation in central Guizhou, while in the lower part of Yanwangbian Formation,south Shanxi Mianxianella and Qingzhenaspis intergrow with Drepanuriodes and Drepanopyge of Drepanuriodes Z. Therefore,Mianxianella---Qingzhenaspis Ass. z. can be contrasted with Drepanuriodes Z.. A new species of Meitanella which is an important genus of Mianxianella---Qingzhenaspis Ass. Z. is described in this paper.
