AB The Iberian Chain developed by inversion of Mesozoic rifts of the Iberian Basin during the Paleogene. TheMaestrat and Cameros basins developed during the Late Jurassic-Early Cretaceous rifting cycle 2. Thereare two main controls on sedimentation: (1) tectonics, (2) climate, and these together control sea-leveland paleoecosystems. Cameros and Maestrat basins display different styles of extensional tectonic structureprobably due to a crust thermally weakened. Biotic changes in freshwater plants, continental faunas, andmarine carbonate producers, reveal the evolution from Late Jurassic-Earliest Cretaceous climate to showhydrological seasonality in a general warm and humid context. This is confirmed by the coexistence ofbiotic markers of hydrological stress (closed stomatal structures in plants, small size in animals) withsedimentologic indicators of a long-lasting humid climate (lateritic soils and karstic bauxite deposits). Thelong-term global sea-level curve fits the main transgressive-regressive evolution of the Maestrat basin withsome local tectonic disturbances
