The areas covered by this stratigraphical revision are located in southern France, north-central and northeast Spain. Paleoenviron-ments are either fluviatile, lacustrine, lagoonal, estuarine or terrestrial. Four divisions have been established in Provence on the basis of plant macrofossils, molluscs and vertebrates : Valdonnian, Fuvelian, Begudian and Rognacian. New data from these fossil groups, as well as from pollen, spores, charophytes and ostracods confirm and define more accurately these divisions. Four zones, mainly based on charophytes, are established : one for the Valdonnian Fuvelian (regarded as equivalent to the Campanian) and three for the Begudo-Rognacien (regarded as equivalent to the Maas-trichtian). This zonation may be ap...
