Abstract—The present study was carried out at the Banyuurip area in the East Java Basin, Indonesia, a site contains nannofossil assemblages of Pliocene to Pleistocene, with lithology is suitable for nannoplankton research. Methods used in this research include making a Stratigraphical section Measurement, collecting 41 samples and preparing the samples with the smear slides method to be observed using a polarizing microscope with 1000x magnification, and preparing several rock samples using SEM analysis. Analysis of nannofossil resulted in identifying 19 genus and 51 species. Biostratigraphic zone of this study can be arranged into 9 biostratigraphic zones. The zone order from older to younger are: a) Sphenolithus neoabies Zone /NN12/Late Miocene to Early Pliocene, b) Ceratolithus rugosus Zone /NN13/Early Pliocene, c) Discoaster asymmetricus–Reticulofenestra pseudoumbulicus Range Zone/NN14-NN15/Early Pliocene to Middle Pliocene, d) Discoaster surculus Zone/NN16/Middle Pliocene, e) Discoaster pentaradiatus Zone/NN17/Late Pliocene, f) Discoaster brouweri Zone/NN18/Late Pliocene, g) Gephyrocapsa caribbeanica Zone/NN19 Zone/Early Pleistocene, h) Gephyrocapsa oceanica Zone/NN20 Zone/Middle Pleistocene, and i) Emiliania huxleyi Zone/NN21 Zone/Late Pleistocene.
