Eleven measured stratigraphic sections were taken from sedimentary rocks which are outcroped in the study field. According to lithostratigraphic and biostratigraphic correlation of these sections, it was determined the stratigraphic positon of the investigation area. Systematic sampling was also carried out during the stratigraphic section measurement. It is identified that; 11 genus, 10 species from the samples are belonging to Fçıtepe Formation. According to the stratigraphic level and paleogeographic distribution of the fauna, Fıçıtepe Formation’s age is found as Late Eocene. Identified fauna represent that the shallow marine brackish water envorinment during the Late Eocene. At the same time, 36 genera, 34 species have been identified belonging to Danişmen Formation which unconformably overlying on Fıçıtepe Formation. In the light of these fauna, the age of Danişmen Formation is found as Late Oligocene and interpreted that warm, shallow, sublitoral and brackish water conditions were dominant. © SGEM2016.eninfo:eu-repo/semantics/openAccessBiga Peninsula; Mollusca; Paleoecology; Paleogene; StratigraphyConference Object146146810.5593/SGEM2016/B11/S01.0582-s2.0-84994081861Q4
