Eleven dinoflagellates, acritarchs, and pollen biozones have been identified in Upper Eocene to Pliocene sediments combined from MuS, Tekman, Tercan-ASkale, Pasinler-Horasan basins and the Bayburt-Kars Plateau in this study. FAD& / #8217 / s of Compositae (tubuliflorae type), Slowakipollenites hipophä / eoides, Mediocolpopollis compactus, Monoporopollenites gramineoides and Umbelliferae at the base of Rupelian, FAD of Wetzeliella gochtii in the middle Rupelian, LAD of Ascostomocystis potane in the late Rupelian, LAD of Wetzeliella gochtii in the latest Rupelian, LAD of Deflandrea spp. in the latest Chattian, peak occurrences of Chriptoredium spp. in the early and late Aquitanian, FAD of Hystrichosphaeropsis obscura, followed by FAD of Membranilarnacea ?picena in the late Aquitanian should have particular emphasis for palynostratigraphic divisions in regional correlations and indicate that a continuous deposition took place in Eastern Anatolia from Late Eocene to the end of the Early Miocene. A relatively deeper marine deposition prevailed during the Late Eocene, which was followed by a shallowing-upward deposition during the Oligocene in MuS, Tekman, Tercan-ASkale, and Pasinler-Horasan basins. These basins were also characterized by an Early Miocene regional transgression, and terrestrial (lacustrine and fluvial) deposition during the Late Miocene-Pliocene whereas terrestrial conditions have been predominating since Late Eocene in the Bayburt-Kars Plateau. Paleoclimatological reconstructions of Eastern Anatolian Oligocene-Miocene sediments suggest temperate to subtropical climates in which mean annual temperatures vary between 15,6 to 21,3 ° / C, mean temperatures of the coldest and the warmest month are 5.0 to 13.3 ° / C and 24.7 to 28.1 ° / C, respectively, and mean annual precipitation is 1122.0 to 1522.0 mm.
