DANUTA PERYT PLANKTIC FORAMINIFERA ZONATION OF THE UPPER CRETACEOUS IN THE MIDDLE VISTULA RIVER VALLEY, POLAND (plates 1-23) PERYT D., 1980: Planktic Foraminifera zonation of the Upper Cretaceous in the Middle Vistula River valIey, Poland. Palaeontologia Polonica, 41: 3-101 Abstract. - Planktic foraminifera from the Upper Cretaceous deposits of the Vistula River valIey of Central Poland, the most complete exposed section of the Upper Cretaceous in Europe, have been studied . In this section, comprising Ceno manian to Maastrichtian deposits, 90 species of planktic foraminifera were identified , 5 of them being new: Dicarine//a longoriai, Marginotruncana caronae, Globotruncana pozaryskae, Chiloguembelina praecursor, Heterohelix vistulaensis. On the basis of this assemblage 10 foraminiferal zones have been distingui shed : Hedberge//a planispira Assemblage-Zone, Rotalipora cushmani Range-Zone, Helvetoglobotruncana helvetica Interval-Zone, Marginotruncana coronata Interval-Zone, Globotruncana lapparenti Interval-Zone, Globotruncana fornicata Interval-Zone, Globotruncana area Interval-Zone, Globi gerine//oides multispinus Interval-Zone, Rugoglobigerina pennyi Interval-Zone, Guembelitria cretacea Range-Zone. This zonation has been correlated with other zonations based on cephalopods, inocerarns and coccoliths of the region studied as welI as with foraminiferal zonations proposed for other regions of the world .

Streszczenie. - Opracowano otwornice planktoniczne z osad6w g6rnej kredy, odslaniajacych sicr w dolinie Wisly, stano wiacych najbardziej kompletny, naturalnie odsloniety profil osad6w tego wieku w Europie. Og61em, w osadach od ceno manu do mastrychtu, stwierdzono 90 gatunk6w, w tyrn 5 nowych: Dicarine//a longoriai, Marginotruncana caronae, Globo truncana pozaryskae, Chiloguembelina praecursor, Heterohelix vistulaensis.
