Lower Miocene deposits of the Guneyce Formation formerly described as the Elmali Formation of Lutetian-Burdigalian age are located near the villages of Gokcebag (Burdur) and Yakaoren (Isparta), (southwestern Turkey), Eastern Mediterranean, and overlie the pre-Neogene tectonostratigraphic units of the Isparta Angle. The purpose of this study is to discuss new biostratigraphic data calibrated to originally classified nannofossil records. Three Early Miocene nannofossil biozones, NN1 - Triquetrorhabdulus carinatus Zone, NN2 - Discoaster druggii Zone and NN3 - Sphenolithus belemnos Zone, were defined in clastic sediments of the Guneyce Formation. In addition, one Lutetian biozone, NP16 - Discoaster tanii nodifer Zone, was recognized in the remaining outcrops of the Isparta Formation unconformably underlying the Guneyce Formation.
