Plant assemblage from Opole, southern Poland : new data on Late Cretaceous vegetation of the northern part of the European Province

Abstract This paper presents the results of studies on plant macroremains found in the upper Turonian of the Folwark Quarry, Opole, Poland, associated with palynological studies of the host rocks. In addition to a few macrofossils (gymnosperm wood, conifer Geinitzia reichenbachii and fern ? Didymosorus ) rich sporomorphs (bryophyte, lycopod and fern spores, conifer and angiosperm pollen grains) and marine palynomorphs (mainly dinoflagellate cysts) were recorded. The palynological analysis revealed that the vegetation on the neighbouring land (the East Sudetic Island) in the late Turonian was much more diverse than could be reconstructed based on only macrofossil remains. The latter are taxonomically restricted and dominated by one gymnosperm species ( Geinitzia reichenbachii ), which make them similar to most neighbouring, coeval Central European assemblages. Its over representation is, thus, a result of taphonomy.
