The data of new ammonite finds are presented, the detailed results of paleomagnetic, petromagnetic and magneto-mineralogical research are described. The ancient nature of the selected characteristic remanent magnetization (ChRM) is proved on whose basis within the subzone of Neocosmoceras euthymi (zone boissieri) two magnetozones of reversed and normal polarity are identified. Magnetostratigraphy section is consistent with paleomagnetic zonation of coeval sediments (Subzone Malbosiceras paramimounum zone boissieri) in a Berriasian stratotype (France), this fact allowed to justify and refine infrazonal correlation of the Upper Berriasian of the Crimea and Western Europe and to identify selected magnetozones with magnetic crones M16r and M16n, respectively.
