Calcareous nannofossils of the Wungkal Formation in the Bayat area were studied in order to obtain new age-diagnostic data. Previously, the Paleogene sediments in the formation have been determined as Eocene based on the assemblage of larger foraminifera. The nannofossils observed in the Wungkal Formation range from the late Eocene (CP 14) to early Oligocene (CP 16 c). The Eocene/Oligocene boundary is recognized by the last occurrence of Discoaster saipanensis, Discoaster barbadiensis and Cribrocentrum reticulatum. The Subzone CP 16 c in the upper part of the section was identified by the co-occurrence of Reticulofenestra umbilicus, Cyclicargolithus floridanus and Reticulofenestra bisecta.
