Ostracod biostratigraphy and Strontium isotope stratigraphy of the Miocene sequences of the Ayrancı Basin (Karaman/Turkey)

We investigate the stratigraphy of the Miocene fossil ostracod fauna from the Ayrancı Basin in southern Turkey, based on five key stratigraphic sections. Abundant ostracods belonging to the Neomonoceratina helvetica-Aurila soummamensis Biozone were found within the limestones of the Mazı Formation....
