Agglutinated Foraminiferal Acmes and Their Role in the Biostratigraphy of the Campanian–Eocene Outer Carpathians

The biostratigraphy of the Outer Carpathians is based mainly on ranges agglutinated foraminifera. Species acmes provide opportunity to enhance and support existing biozonations. Assemblages foraminifera from Campanian Eocene various tectonic-structural units were analyzed in terms their qualitative quantitative occurrence. In this stratigraphic interval, 19 species display significantly increased abundance within a relatively short interval: Caudammina gigantea (Geroch) (upper Santonian–lowermost Maastrichtian), ovulum (Grzybowski) (Campanian–Danian), Placentammina placenta (Grzybowski)-Saccammina grzybowskii (Schubert) Campanian–Danian), excelsa (Dylążanka) (lowermost Maastrichtian–Danian), ovuloides (Danian–Selandian), Hormosina velascoensis (Cushman) Danian–Selandian), Praesphaerammina gerochi (Hanzlíková) (Thanetian), Glomospira charoides (Jones et Parker)-Glomospira gordialis Parker) (uppermost Thanetian–lowermost Ypresian), Trochammina spp. Thanetian–lower Reticulophragmium amplectens (Lutetian–Bartonian), Reophax duplex (Grzybowski)-Reophax “pilulifer” Brady group taxa (Lutetian–Priabonian), Haplophragmoides walteri (Grzybowski)-Haplophragmoides nauticus Kender, Kaminski Jones Spiroplectammina spectabilis “Ammodiscus” latus Grzybowski (Bartonian–Priabonian), subgaleata (Vašíček) (Lutetian–Bartonian). biostratigraphic position data with are presented.
