The recognition of regional ammonite bio-events spanning the late Barremian–early Aptian interval in Provence invalidates previous chronostratigraphic models of the Urgonian carbonate platform. Based on high-resolution correlations across the Provence platform and the Vocontian Basin, this study provides a comprehensive revision of the temporal and spatial evolution of this sedimentary system through the definition of seven depositional sequences. Close to the early–late Barremian transition, the South Provence domain was marked by the inception of rudistid, Agriopleura-dominated, carbonates, while further to the North, the expansion of the latter biota was delayed, presumably due to greater subsidence rates driven by extensive E–W-trending basement faults. Northward installation of a rudist-rich succession in the North Provence region – including, from oldest to youngest, the Agriopleura, requieniid …
