Since 1994, the project of archaeological research in the Moroccan Oriental Rif (Prehistory and Protohistory of the Eastern Rif), is carried out by a cooperation of the Kommission für Archäologie Außereuropäischer Kulturen (KAAK), Deutsches Archäologisches Institut (DAI) and the Institut National des Sciences de l’Archéologie  et du Patrimoine du Maroc (INSAP). Due to its particularly rich stratigraphy, with the Middle Palaeolithic/ or Middle Stone Age sequence dating to 83 ± 6 ka to 130 ± 8 ka for the upper levels and to 145 ± 9 to 171 ± 12 ka for the lower levels, the rock shelter of Ifri n’Ammar became quite quickly the focus of all local activities.  Indeed, the site has ideal conditions for a prehistoric settlement by its topographical location. The rock shelter is located at the edge of a narrow valley rock Selloum at the confluence of two wadis. The area is situated between the Guerouaou and the Moulouya plain. It’s a mixture of highlands and alluvial plains, favorable biotopes for the fauna that reveal several advantages for hunters and gatherers during the Middle and the Upper Pleistocene.
