Abstract: Late Albian abundant and diversified foraminifers and calcified radiolaria representing the Planomalina buxtorfi-Rotalipora appenninica Zone, and single Cenomanian planctonic foraminifers have been found as redeposited assemblages within lower-middle Campanian and Paleocene flysch deposits of the Raca Subunit, Magura Nappe, Polish Western Carpathians. The Late Albian foraminifers derived from the source area located at the NW margin of the Magura Basin, whereas the Cenomanian foraminifers derived from the SE periphery of the basin. The presence of such microfauna is interpreted as an occurrence of a submarine plateau with pelagic deposition, under lower neritic-upper bathyal depths in the marginal parts of the Magura Basin, during the Late Albian-Early Cenomanian. This assumption was used for reconstruction of the Late Albian-Early Cenomanian paleogeography of the Magura Basin.
