Abstract

Taxonomic revision of the genus Bollitruncana O.A. Korchagin, 2001 shows that it accommodates a directional lineage, which consists of two species: B. carpathica (Scheibnerová, 1963) and B. posthelvetica (Hanzliková, 1963). Bollitruncana directional lineage is restricted to Turonian. A new planktic foraminiferal biozone is recognized in the Turonian, namely the Bollitruncana carpathica Biozone.
