Paleogene Molluscan Fauna and Biostratigraphy Between Kuscu and Macun village, Temelli (SW Ankara)

In this study, paleontological and biostratigraphic characteristics of the Paleogene geologic units outcropping between Kuscu and Macun villages located around Temelli district, Polatli, Ankara. We have examined the patterns of Pelecypoda and Gastropoda samples. Seven measured stratigraphic section from the west of Macun village to east of Kuscu village, which contains the Pelecypoda and Gastropoda patterns, reach total thickness of 52 metres. As a result of field studies, seven species belongs to class of Pelecypoda and one of the new sixteen species belongs to class of Gastropoda have been described. Considering paleogeographic distribution and biostratigraphy of described fauna, it is quite proper to propose that they represent Thanetian age and can be interpreted as belonging to Kirkkavak Formation. Furthermore, the paleoecologic characteristics of the fauna strongly suggests that the shallow and temperate coastal marine facial conditions were prevalent at the region during that time span.
