Paleogeographic reconstructions of the evolution of Pyrenean synorogenic basins, orogenic relief and sediment supply from base Campanian to Oligocene. Using the free G-Plates 2.0 software (Müller et al., 2018) present-day coastlines were restored back in time following the plate kinematic model of Macchiavelli et al. (2017) for the western Mediterranean. Paleoenvironments are based on Plaziat (1981), Debrand-Passard et al. (1984), Barnolas and Courbouleix (2001), Serrano et al. (2006) and Monod and Bourroullec (2014) with restorations by G. Frasca using balanced cross-section presented in Figures 7 and 8 and Vergés (1993). Deformation characteristics (timing, principal structures, amount of shortening) and basin evolution (basin limits, dynamics, major facies, paleocurrents) were integrated using published data. Uncertainties related to the plate kinematic model were reduced by assuring that each step honored data on vertical motion, structural and stratigraphic history.
