Abstract: In the Magura Group of nappes, Cretaceous sediments were proved in the Raca and Bile Karpaty units nearly in the whole range of the period. This was made possible by new biostratigraphic (foraminifers and calcareous nannofossils) and biofacies data. In the present paper, the Kurovice Klippe, Gault Flysch, Kaumberg Formation and the lower part of the Solan Formation are included in the Raca Unit, while the Hluk, Kaumberg and Javorina formations and the lowermost part of the Svodnice Formation are placed in the Bile Karpaty Unit. Some lithostratigraphic units of Senonian age appear in tectonic slices only (Puchov Marl and Antoninek Formation) which makes their incorporation into the paleogeographical model of the Magura Group of nappes difficult.
