New larger benthic foraminifera from Brač Island, Croatia: Further evidence for early–middle Campanian foraminiferan high diversity in the inner platform facies of the Adriatic Carbonate Platform

Abstract

Four new species of larger benthic foraminifera are described from lower–middle Campanian inner-platform carbonates of the island of Brač, Croatia: Bakhtiarella minima sp. nov. (family Bakhtiarellidae), Biconcava brattiana sp. nov. (family Mayncinidae), Paravanneauina campaniana gen. et sp. nov. and Calveziconus pygmaeus sp. nov. (family Orbitolinidae). The latter two taxa are also reported from time-equivalent strata of the Gavrovo–Tripolitza Platform, southwestern Greece. The new taxa provide further evidence for the pronounced Campanian diversification within the Late Cretaceous Global Maturation Cycle of larger benthic foraminifera in the inner platform facies of the Mediterranean Adriatic Carbonate Platform.
