Decouverte d'Ammonites du Lias inferieur et moyendans la zone predorsalienne de la region de Jebha (Rif,Maroc) et ses consequences

Jurassic from rifean “Dorsale” furnished only rare paleontological documents; so it's interesting to point outhere, in the predorsalian zone, associations of ammonites from Domerian (Fuciniceras, Protogrammoceras), from Sinemurian (Charmasseiceras, Epammonites) and from Hettangian (Waehneroceras), this one beeing in this way well characterized for the first time in this zone.
