Unconformity found along the Lgezira Beach, north of Sidi-Ifni, Morocco. This contact shows that the Anti-Atlas basement rocks were at the surface during the deposition of the coarse clastics. New fossil control allows us to give a Jurassic age to the redbeds, while they are mapped as Early Cretaceous on all geological maps.
