| 摘 要： | 三叶虫是二叠纪末生物集群灭绝中消失的生物门类之一,但是关于该门类生物化石在中国消失的确切层位未见报道。贵州安顺新民剖面大隆组顶部的三叶虫化石Pseudophillipsia sp.产于火山成因的黏土岩之炭质泥岩夹层中,相邻的泥灰岩结核中产牙形石化石Clarkina meishanensis。该黏土岩及炭质泥岩夹层可以与浙江长兴煤山D剖面的第25层对比,这说明三叶虫延续到了主灭绝事件层位,对研究二叠纪末生物集群灭绝的原因具有一定的意义。

| Abstract: | Trilobites became extinct during the end-Permian mass extinction.However,the exact horizon at which trilobite went extinct is not clear.The trilobites reported here,Pseudophillipsia sp.,are collected from the uppermost part of the Dalong Formation at the Xinmin section of Anshun,Guizhou.They are discovered from carbonaceous mudstone interbeds of bentonites covered by marl with Clarkina meishanensis.The bentonite and marl beds can be correlated with beds 25 and 26 at Meishan D Section in Changxing,Zhejiang a... |
