Table 1 Palaeoecological preferences of selected Upper Cretaceous nannofossil species. Modified after Table 2 from Sheldon et al. [53]. The specimens were counted in the smear slides. The specimens without numbers were not determined in the assemblage. Rich = at least one specimen every 2 fields of view. Rare = at least 1 specimen determined by scanning electron or cross-polarised microscope. Micula staurophora can correspond to M. decussata according to literature
