福建武平宁洋Polydiexodina-Neomisellina-Codonofusiella类动物群及其地层意义

NINGYANG′S Polydiexodina FAUNA AND ITS STRATIGRAPHIC SIGNIFICANCE IN WUPING COUNTY,FUJIAN PROVINCE

武平宁洋下二叠统上部含(?)灰岩中,发现丰富的(?)类、腕足类、非(?)有孔虫等化石。本文论述(?)类动物群组合特征及其时代,确立了 Polydiexodina-Neomisella 组合,为本区早二叠世晚期的最高(?)类化石带。文章详细描述和讨论了Neomisellina wupingensis sp.nov.

Abundant fossils of Fusulinida,Brachiopoda and non-Fusulinida foraminifera have been found infusulinid limestone of upper part of Lower Permian in Ninyang area,Wuping County.The paper pre-sents a discussion of the assembly features and date of Fusulinida fauna,establishes an assemblage ofPolydiexodina-Neomisellina-Codonofusiella as the highest fusulinid fossil zone for late stage of Early Permi-an,and discribes in detail the Neomisellina wupingensis sp.nov.
