Colonization by marine organisms such as foraminifers, molluscs, bryozoans, brachiopods and red algae during the Middle Miocene (Early Badenian) transgression near Přemyslovice (Carpathian Foredeep) was initially affected by a cool water current of unclear origin. However, shortly afterwards, fallout of volcanic material caused a total termination of the biota. After this catastrophe, the biota started recolonize the area. The succeeding association, adopted to warm-water input, is characteristic of the climatic optimum during the Early Badenian and is comparable with those of other sections referred to this interval in the Carpathian Foredeep (such as Kralice nad Oslavou, Podbřežice, and Hluchov).
