Maastrichtian brachiopods from Ciply: palaeoecological and stratigraphical significance

Maastrichtian brachiopods from the phosphatic chalk of Ciply and brachiopods collected in the sediments trapped in the cavities of the overlying hardground were studied for their palaeoecological significance. Stratigraphical correlations with the micromorphic brachiopod zones described by SURLYK for the white chalk of Denmark and Northern Germany are proposed. A new species of Isocrania JAEKEL, 1902 and a new species of Rugia STEINICH, 1963 are described.
