Abstract
A newly proposed biostratigraphic zonation of Early Cretaceous microfossils (mainly foraminifera) improved the resolution for dating the shelf carbonate platform deposits from Cernavodă-lock section, South Dobrogea, eastern part of the Moesian Platform. The zonation comprises 12 zones (biozones) for the Upper Berriasian-Valanginian-Lower Hauterivian. Benthic foraminifers marker are represented by Protopeneroplis ultragranulata, Andersenolina elongata, Dobrogelina anastasiui (Upper Berriasian), Haplophragmoides joukowski, Montsalevia salevensis, Carasuella cylindrica (Lower Valanginian), Danubiella gracilima, Rumanoloculina robusta, Meandrospira favrei (Upper Valanginian), respectively Protopeneroplis banatica, Vercorsella tenuis, Moesiloculina danubiana (Lower Hauterivian). The new biozonation scheme has allowed correlation of the studied succession with other major paleogeographic realms on the Romanian territory, in the eastern part of the Moesian Platform including South Dobrogea, in the Eastern Carpathians (Hăghimaş Mts., Transylvanian Carbonate Platform), the South Carpathians (Getic Carbonate Platform), the Apuseni Mts., as well as with Tethyan shelf basins of the European margin (France, Jura, Mont Saléve, Sardinia, Abruzzi Mts., Dinarides, Northern Calcareous Alps, West Carpathians, Stramberk Limestones) and the Western Pontides, Anatolia (Turkey).
