Ultrastructure of ostracods as a stratigraphical tool for the subdivision of the Senonian sequence in Israel

Avraham Honigstein

Abstract. Ultrastructural size variations in pitted and ornamented Senonian ostracods from Israel are valuable to distinguish subzones in full successive sections. Pit and pore sizes of different genera are inversely correlated. Peaks of pit diameters from different locations are indicative of certain levels and therefore applicable to biostratigraphic correlations.
