ORIGIN, EVOLUTIONARY CLASSIFICATION, AND BIOSTRATIGRAPHIC SIGNIFICANCE OF THE LATE CRETACEOUS PLANKTIC FORAMINIFERAL DIRECTIONAL LINEAGE BOLLITRUNCANA O.A. KORCHAGIN, 2001. Authors: . |

Abstract:
Taxonomic revision of the genus Bollitruncana O.A. Korchagin, 2001 shows that it accommodates adirectional 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 foraminiferalbiozone is recognized in the Turonian, namely the Bollitruncana carpathica Biozone. Key words: planktic foraminifers, Late Cretaceous, taxonomy, evolution, biostratigraphy.
