Defining the Early Neolithic of the Eastern Rif, Morocco - Spatial distribution, chronological framework and impact of environmental changes

摘要

We provide a detailed chronological framework for the Early Neolithic of the Eastern Rif of Morocco. Neolithic innovations such as pottery and domestic plants begin ca. 7.6 ka calBP, at which time plant cultivation is clearly documented for cereals (Triticum monococcum/dicoccum, Triticum aestivum/durum, Hordeum vulgare) and pulses (Lens culinaris, Pisum sativum, Vicia faba). This represents the earliest evidence for Africa as a whole. The Early Neolithic ends ca. 6.3 ka calBP and is marked by the definitive disappearance of Cardium-decorated pottery. The disintegration of the Early Neolithic dates to the interval 6.6-6.0 ka calBP, during which time a gradual desiccation of the Sahara has been observed. In the Eastern Rif of Morocco, Saharan influences become visible after 6.0 ka calBP. These are characterised by the presence of ivory objects and the appearance of comb-impressed pottery with so-called herringbone motives. (C) 2016 Elsevier Ltd and INQUA. All rights reserved.
