Abstract:
Qualitative and quantitative analyses of calcareous nannofosills from Cores 28 and 29, Site 356, DSDP/ODP Leg 39, found in 18 m of nannofossil-and foraminiferal-rich calcareous mudstone, in the interval uppermost Maastrichtian and the lowermost Danian provided a continuous record of the Cretaceous/Paleogene boundary. 24 species were identified in the Maastrichtian, and 35 in the lower Danian. The following biozones were recognized: UC20 Zone, Markallus inversus Zone, Cruciplacolithus tenuis Zone, and the Chiasmolithus danicus Zone. Acme events of Thoracosphaera sp. (lowermost Danian) and Praeprinsius dimorphosus (lower Danian) were observed.
