Some species of genera in the Superfamily Globotruncanacea Brotzen, 1942 are biostratigraphically important in the Turonian of the Tethyan (Tunisian Atlas, Western Carpathians of Slovakia) and Boreal (Bohemian Cretaceous Basin) realms. The microbiostratigraphical difference is manifested in the Early Turonian of the Western Carpathians by the absence of the genus Whiteinella Pessagno. Further on the difference is in the upper part of the Helvetoglobotruncana helvetica Zone, in which the species Caronita turona (Olbertz), present in the Bohemian Cretaceous Basin and Western Carpathians, is missing in other parts of the Tethyan Realm. On the contrary, the species Caronita kalaati (Gonzales Donoso and Linares, 1990) and Caronita pileoliformis (Lamolda, 1977) are present. The Late Turonian of the Tethyan Realm is extraordinarily rich in planktic and benthic foraminifers which are also characterized by a considerable variability. In the Late Turonian of the Western Carpathians, microfauna was impoverished, still more distinctly than in the Boreal Cretaceous Basin of the Bohemian Massif However, benthic microfauna is very diverse and variable as to genera and species. Three new species are described: Concavatotruncana praeconcavata n. sp., Caronita mellegiana n. sp. and Falsomarginotruncana barri n. sp.
