Abstract
Late Albian abundant and diversified foraminifers and calcified radiolaria representing the Planomalina buxtorfi-Rotalipora appenninica Zone, and sing le Cenomanian planktonic foraminifers have been found as redeposited assemb lages within lower-middle Campanian and Paleocene flysch deposits of the Ra ca Subunit, Magura Nappe, Polish Western Carpathians. The Late Albian foram inifers derived from the sourer: area located at the NW margin of the Magur a Basin, whereas the Cenomanian Foraminifers derived from the SE periphery of the basin. The presence of such microfauna is interpreted as an occurren ce of a submarine plateau with pelagic deposition, under lower neritic-uppe r bathyal depths in the marginal parts of the Magura Basin, during the Late Albian-Early Cenomanian. This assumption was used for reconstruction of th e Late Albian-Early Cenomanian paleogeography of the Magura Basin.
