...Hartmut Mai Abstract The same specimens of Neobiscutum romeinii, Neobiscutum parvulum and Cruciplacolithus primus, with an average size of 2.0 mu m and deriving from the "type locality" of the Maastrichtian stage at ENCI quarry near Maastricht, The Netherlands, were documented both under the light...

...Hartmut Mai; Robert P. Speijer; Peter Schulte Abstract The calcareous nannofossil species Neobiscutum romeinii , N. parvulum, and Cruciplacolithus primus , are considered in modern zonation schemes as index species for the lowermost Paleocene. Our studies, however, reveal that they are consistently...

... reinhardtii, Markalius inversus, Octolithus multiplus and new Tertiary, dwarf species (Neobiscutum romeinii, N. Parvulum). The blooms are different in the studied sections probably as a result of their different paleogeography, paleodepth and consequent distribution of nutrients at the different sites...

... and of the nannofossil Braarudosphaera bigelowii (Fig. 5 ). The FO of the nannofossil Neobiscutum parvulum succeeds Biantolithus sparsus , whose extinction occurs within the interval of peak abundance blooms of predominant species at that time, Thoracosphaera and Braarudosphaera bigelowii . In the present...
