Quantitative palynofloral analysis of late Berriasian to early Hauterivian aged sediments from the Vocontian Basin of southeast France has involved fifty-four outcrop samples from Vergol (Montbrun-les-Bains) and twenty-seven from La Charce (Serre de l’Âne). All samples were marls except for two from the early Valanginian Barrande layers, thin black layers rich in organic carbon. Sampling was focused particularly on the Berriasian/Valanginian, early/late Valanginian and Valanginian/Hauterivian boundaries with two of these particularly important as La Charce is the GSSP for base Hauterivian and Vergol is a GSSP candidate for base Valanginian. Although little has been previously published on the palynology of the Vocontian Basin, this study has benefitted from many previous multi-disciplinary studies in the area; the numerous palynofloral events recorded are tied closely to the standard ammonite zonation. Analyses were mainly focused on the dinocysts, but miospores have also been considered in terms of their palaeoenvironmental response, allowing broad assessment of relative sea level changes. Some linkage between peaks in coastal/lowland ratios, the ?13C curve through the Weissert carbon isotope excursion (CIE) and the Muderongia group (possible reduced salinity) have been shown. A new dinocyst zonation scheme is proposed, involving twelve zones, eight of which cover the Valanginian; previous schemes are briefly discussed. Two genera, twenty-three species and five subspecies of stratigraphically-significant dinoflagellate cysts are described as new, two genera have been emended and thirteen new combinations have been proposed. The diagnosis of one acritarch genus has been emended and two new combinations effected.
