ACKNOWLEDGEMENTS

Midd~e and Late Miocene (Late Badenian and Sarmatlan) foraminifera of the epicontinental deposits of SE Poland (Roztocze area) have been examined. These deposits, referred to the Late Badenlan are correlated with NI3-N14 s tan da rd b io stratigraphic zones, based on planktonic foraminifera. Sarmatlan, therefore, especially it s deeper wate r deposits, appears to represent younger zones. Changes in water depth appeared to control distribution of benthonic forms, whereas climatic changes and water depth controlled d istribution of pl anktonic forms. The Mlddle/Late Badenlan boundary probably r epresents an ecos t r a ti gr a phi c event. A correlation is su ggested r elating the Middle Miocene deposits of the Roztocze area with those of.the Polish Fore-Carpathian Depression. Bolboforma badenensis sp. n., a planktonic form of uncertain taxonomic affinity Is described.
