The paper considers the results of the analysis of the taxonomic composition of planktonic foraminifera (PF) from the end of the Late Campanian in the Pacific Ocean. To identify the latitudinal-zonal faunas of the PF, an assessment was made of the species similarity and differences of the PF complexes of the same age from different wells. Based on the difference in species composition, the fauna of the PF is divided into non-arctic regional and oceanic latitudinal-zonal: subtropical western, tro
