摘要
本文根据三叶虫分类的主要要求结合线性相关分析,对产于贵州剑河寒武系"清虚洞组"的已经定种的褶颊虫目的三叶虫Mufushania cf. nankingensis Lin,1965进行重新划分,认为原本划分为Mufushania cf. nankingensis Lin,1965,由于埋藏因素导致标本出现挤压形变从而影响属种的准确划分,应该属于Probowmania (Mufushania) nankingensis Lin,1965。
Based on the trilobites’ morphology and linear analysis,the Mufushania cf nankingensis Lin,1965,collecting from the Cambrien Jianhe,was classified into the Probowmania( Mufushania) nankingensis Lin,1965.It could conclude that the burial factors caused the specimen changing and therefore affected the accurate classification of genus and species.
