Korelacja podziałów amonitowych i dinocystowych przy granicy oksfordu i kimerydu na podstawie profilów wierceń Bartoszyce IG 1 i Kcynia IG IV

Detailed study of ammonite and Dinoflagellata assemblages from the Bartoszyce IG 1 and Kcynia IG N cores in northern Poland comprises the stratigraphical interval at the Oxfordian/Kimmeridgian boundary. Correlations along well defined biostratigraphical horizons between the particular ammonite subdivisions typical of different biogeographical provinces and subdivisions based on Dinoflagellate cysts are discussed.
