| 摘 要： | 山东平邑盆地固城组、卞桥组共发现介形类化石21属21种4比较种13未定种,本文记述了其中的17属16种4比较种9未定种。卞桥组一段下部的介形类可称为Talicypridea reticulata-Mongolocypris longa-Frambocythere fangjiaheensis介形类动物群,含化石地层的时代被确认为晚白垩世最晚期,即马斯特里赫特期的晚期。该动物群的发现,为平邑盆地白垩系/古近系界线的确定提供了十分重要的依据。

| Abstract: | The ostracod fossils were found from the Gucheng Formation and the Bianqiao Formation of the Pingyi Basin,Shandong including 21 genera and 21species(4cf.species,13 indet.species).This paper deals with 17 genera,16species(4cf.species,9indet.species).The ostracod fossils from the first Member of the Lower Bianqiao Formation can be regarded as Talicypridea reticulata-Mongolocypris longa-Frambocythere fangjiaheensis assemblage.The fossils-bearing strata suggest its age of the Late Maastrichtian(latest Cretaceous).The discovery of the fauna provides an important basis for the determination of the Cretaceous/Paleogene boundary in the Pingyi Basin. |
