Biostratigraphy of larger foraminifera in the Eocene (upper Ypresianlower Bartonian) sequences of the Southern Slope of the Western Caucasus (Russia, NE Black Sea). Correlation with regional and standard planktonic foraminiferal zones
The biostratigraphic analysis of two Eocene (Upper Ypresian-Lower Bartonian) sections located on the Southern Slope of the Western Caucasus (Inal and Loo sections in the Tuapse and Sochi districts, respectively) was carried out using planktonic and larger foraminifera. The planktonic foraminiferal a...
