Abstract :The study area is located in the southern part of the Central Anatolia Neogene Basin insert ignore into journalissuearticles values(north of Karapınar Town and  Acı Göl, Konya);. The İnsuyu Limestone Unit, which has a total thickness of 100-400 m, is composed of claystone,  sandstone, conglomerate and chert. There are also andezite and pyroclastic interclations within İnsuyu limestone.  The claystone layers of this unit are white to pink in color and contain abundant Ostracoda and a few fresh water  Gastropoda. In this study, 160 samples from 8 stratigraphic sections were collected but only samples having  limestone lithology contained ostracods. Atotal of 16 ostracods taxa insert ignore into journalissuearticles values(11 previously known and five belonging to  open nomenclature); are systematically described as  Cyprideis pannonica, C. torosa, Ilyocypris gibba, I. bradyi,  Candona neglecta, C. candida, C. altoides, C. decimai, Pseudocandona compressa, Heterocypris salina,  Zonocypris membranea, Ilyocypris Candona , Candona Pseudocandona Cypridopsis  sp. sp.1 sp.2, sp. and sp.  Based on this Ostracoda fauna, the age of this unit is assigned as Pliocene-Early Pleistocene. This fauna indicates a  few brackish but dominantly fresh water conditions in a lacustrine environment.
