Towards a new definition of the Middle Neolithic in the southern Iberian peninsula: Granena Baja, Jaen

This work presents the results of the first phase detected at the archaeological site of Grafiena Baja (Jaen). The possible existence of a large segmented ditch is one of the most outstanding features, associated with a material culture that has not been specifically characterized in the southern Iberia. The ceramic types stand out for their composite profile and reinforced rims, as well as having decorations simply executed. Blades of medium and large format with straight bases and obtained by means of indirect percussion characterize the lithic industry. Radiocarbon dates place the site's occupation in the third quarter of the 5th Millennium cal BC. This information makes an important contribution to filling the gap between the Early and the Recent Neolithic in southern Iberia, a region where good evidence for the Middle Neolithic is scarce.
