Abstract: In this investigation, 205 samples were collected from five measured stratigraphic sections in the Kasaba Basin (Kas/Antalya, SW Turkey) and 16 genera and 33 species of ostracodes were identified. Three different biozones have been recognized on the basis of the stratigraphic and geographic distribution of ostracod fauna in the measured sections which are, from bottom to top, as follows: 1. Early-Middle Burdigalian age, Cytherella triestina Zone, 2. Late Burdigalian-Early Langhian age, Aurila soummamensis-Krithe papillosa Zone, 3. Langhian age, Cytherella vulgata-Xestoleberis reymenti Zone. These zones have been correlated with the well known and widespread Neomonoceratina helvetica and Aurila soummamensis Zones of other Turkish and Mediterranean Basins. The chronostratigraphic Burdigalian-Langhian correlation of the sequence has been established mainly by Ostracoda assemblages. The results are integrated with the other faunal and floral occurrences observed during the investigation, which include planktonic and benthonic foraminifers, nannoplankton, Bivalvia, Gastropoda and corals. Thus, the Burdigalian (early, middle, late) and Langhian stage boundary has been biostratigraphically identified.
