ABSTRACT: The Hadim Nappe has a relatively complete succession from the Middle(?)–Upper Devonian to Upper Cretaceous in the Taurides. The Bademli section is one of the well exposed sections of theHadim Nappe that is selected for detailed biostratigraphic investigations. It includes a continuous Viséan stratigraphic succession. In the Bademli section, rich and diverse Early-Middle Viesean foraminiferal assemblages were recovered, most of which were reported for the first time in Turkey. Four first occurrence biozones, which approximately correspond to the Zones MFZ10 to MFZ13 of the Belgium stratotype section, are identified based on the foraminiferal analysis of the Lower-Middle Viséan strata of the Bademli section that are Ammarchaediscus-Glomodiscus first occurrencezone, Uralodiscus rotundus first occurrence zone, Pojarkovella first occurrence zone and Endothyranopsis (Reitlingeropsis) intermedia - Endothyranopsis mosquensis first occurrence zone.
