The presence of the Oligocene (upper Rupelian and Chattian)-Lower Miocene (Aquitanian) in the Podhale Flysch sediments is argued by the identification of calcareous nannoplankton zones: NP24, NP25 and NN1. The upper part of the Szaflary beds, the Zakopane beds and the lower part of the Chochołów beds belong to the NP24 Zone based on the occurrence of Helicosphaera recta, Cyclicargolithus abisectus, Sphenolithus distentus, Reticulofenestra lockeri and Reticulofenestra ornata in assemblages. The upper part of the Chochołów beds and the Brzegi beds belong to the NP25 Zone based on the presence of Sphenolithus conicus with the taxa listed above. The youngest Ostrysz beds contain Helicosphaera scissura and Sphenolithus delphix. These species are characteristic for the NN1 Zone (lowermost Miocene).
