Abstract
Ten surface samples of Albian to Danian strata from Madagascar were examined for planktonic foraminifera, calcareous nannoplankton and palynomorphs including dinoflagellates. The stratigraphical results based on these micropaleontologic groups were compared with data based on megafossils, mainly ammonites. In general, the conclusions are closely similar and the differences do not exceed more than half a stage. Special attention is paid to the relationship of Madagscar to the microfloral provinces established for the mid-Cretaceous. Madagascar may be assigned to the Gondwana paleophytogeographic province, probably close to the northern boundary and transitional to the African-South American province.
