Inoceramids and inoceramid biostratigraphy of the Upper Campanian to basal Maastrichtian of the Middle Vistula River section, central Poland

The revised geological log and the biostratigraphy of the Late Campanian and earliest Maastrichtian succession of the Middle Vistula River section, central Poland, are presented. The biostratigraphy is based on inoceramid fauna, basically newly collected. Eight inoceramid zones were distinguished, corresponding, in ammonite/belemnite terms, to an interval from the upper null Bostrychoceras polyplocum null Zone up to the traditional null...
