In this paper the authors give a summary of the Paleocene sedimentation in Poland, its facies, pale:)climatic conditions and add a description of 3 species of warm-water foraminifers, belonging to the genera Boldia van Bellen, Glabratella Dorreen and Baggatella Howe, of which Glabratella polonica and Baggatella aenigmatica are new. These species were found by the present authors in the Pamiętowo boring (Pomerania, northern Poland), in the tuffeau-type sediments of Montian age. The species described here, especially Boldia reinholdi Marie, also occur in the Montian sediments of the western European Province, the so-called Meridional (not Mediterranean) Province, including the Mons Basin, the Paris Basin and the Limbourg Province.
