Calcareous nannofossil assemblages in four middle to low latitude Cretaceous/Tertiary boundary sections in different paleogeographic settings have been analysed. Correlation between the sections is based on the first occurrence of Neobiscutum romeinii, N. parvulum. Cruciplacolithus primus and Futyania petalosa and planktonic foraminiferal zones. Latest Maastrichtian assemblages are abundant and diverse, coccolithophores did not seem to be in decline in the latest Maastrichtian, though periods… CONTINUE READING
