摘　　要：抚顺煤田始新统是研究程度较高地区，特别是西露天组，化石十分丰富。前人仅报导有介形类４属５种，叶肢介１属３种，并报导了孢粉一些特征；本文提出了新的化石种属，包括介形类１０属２３个种，多属淡水金星科，并发现一些腹足类豆螺科化石。并将孢粉划为栎粉高含量组合，栎粉－波形榆粉亚组合，丰富了西露天组生物内容。Abstract A lot of research work with higher level has been done in the study of the Eogene inthe Fushun Coalfield,especially Xilutian Formation with much fossil.The previous re-sults indicate that the Xilutian Formation has four genera and five species belonging tothe Conchostraca and some properties about sporopollen. New genera and species of fossil are advanced in this paper,including ten generaand twenty-three species of the Ostracoda which mainly belong to the fresh waterCypridea,and a lot of fossils of the Bithyniidea of the Gastropoda. The sporopollen isdivided into the high content Assemblage Zone of Quercoidites and the sub-Assemblageof Quercoidites-ulmipollenites undulatus, which enriches the creature content of the Xilu-tian Formation.SUBJECT TERMS:Fushun,Eogene,Xilutian Formation,biostratigraphy
