Аннотация: The analysis of the foraminiferal variations allows the following general trends to be identified: (1) all the taxa show fluctuations in species richness; (2) from the latest Albian-Cenomanian; the Middle Turonian-Santonian and the Campanian-Maastriahtian PF assemblages are characterized by a progressive appearance and diversification of complex taxa; (3) in all intervals K-strategists fluctuate in opposite phase to the r-strategists. These variations of the PF, associated with changes in the characteristics of the paleoenvironments. The OAEs intervals are characterized by increased abundances of elongated-chambered PF.
