RESUMO

Numerous imprints of valves and inner cores of diatoms were revealed by means of a scanning electron microscope on the shells of fossil agglutinating foraminifera Spiroplectammina from the Lower Oligocene deposits of Southern Ukraine. The taxonomic composition of Bacillariophyta, used by foraminifera to build their sceletons, is given. Representatives of at least ten genera were identified including Paralia Heib., Radialiplicata (Z.I. Glezer) Z.I. Glezer, Pseudopodosira A.P. Jouse, Trochosira Kitton, Actinoptychus Ehrenb., and Sceptroneis Ehrenb. We discuss a possible generic composition and ecological preferences of siliceous algae present in the surface layer of bottom sediments of the Maikop basin.
