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.
