Wilpshaar, M. and Leereveld, H., 1994; Palaeoenvironmental change in the Early Cretaceous Vocontian Basin (SE France) reflected by dinoflagellate cysts. Review of Palaeobotany and Palynology 84 (1994): 121-128 A Valanginian-lower Cenomanian composite stratigraphic section of the Vocontian Basin (SE France) has been studied palynologically with emphasis on quantitative dinoflagellate cyst distribution. The overall composition of the dinoflagellate cyst assemblages suggests that the basin never reached a palaeodepth of more than a few hundred meters. Within the dinoflagellate cyst assemblages a distinct basin-wide long-term quantitative change is apparent during the Early Cretaceous reflecting a palaeoenvironmental change from inner neritic to neritic conditions. This change is considered to reflect a relative rise in sea-level.
