Abstract: Crassostrea cyathula (Lamarck 1806), a valuable biostratigraphic marker, was found for the first time in eastern Turkey (Eastern Mediterranean), in the Rupelian-Lower Chattian sedimentary sequences of northeastern Palu, Elazığ region, and its palaeoecological characters, palaeobiogeographic and stratigraphic distribution are discussed. These oyster specimens are also the first abundant macrofossils from the Oligocene sediments of the Sarıbuğday-Kovancılar section, which were formerly only recorded by micropalaeontological data.
