Sections through the Cantabrian (Western transect) and the Basque Cantabrian Basin (Central transect) (after Miró et al., 2021) and through the Mauléon-Basque massifs (Eastern section) (after Lescoutre et al., 2021). Sections show the present-day situation and restorations at middle Cenomanian (96 Ma) and at Barremian (124 Ma) times. These sections are restored respecting area conservation as well as pre-rift marker horizon length conservation. See Fig. 2b for section location. B.: basin; H.: high; BCB: Basque-Cantabrian Basin; SPBT: South Pyrenean Basal Thrust; NPFT: North Pyrenean Frontal Thrust.
