Biostratigraphy of Santonian-Danian calcareous nannofossils and planktonic foraminifera was studied in Goynilk village and close surroundings located in northwest Turkey. Calcareous nannofossil and planktonic foraminifera assemblages from this time interval were investigated in detail in seven stratigraphic sections measured in the Degirmenorti Member, Yenipazar Formation and Seben Formation. The UC12 zone in the Santonian, UC13 zone, UC14a-b(TP) and UC15a-b-c-d(TP) subzones in the Campanian and UC20a-b-c-d(TP) subzones in the Maastrichtian were defined with nannofossil species assemblages.
