Abstract

The authors present a new prehistoric site recently discovered at Ortovero, near Albenga (Savona Province, Italy) in Western Liguria that can be attributed on typological grounds to the Final Epigravettian or to the Sauveterrian. The raw-material characteristics of the chipped stone artefacts resemble those stemming from the red radiolarite outcrops of Eastern Liguria, although the large number of pieces manufactured from this material and the distance from the supposed sources challenge this hypothesis. As a result of field surveys carried out over the last few years, the authors discuss the possibility of a formerly unknown source of vitreous red-coloured radiolarite outcropping in the surroundings of the site that may correspond to the Arnasco radiolarite formation outcropping near Ortovero
Les auteurs présentent la récente découverte d'un nouveau site préhistorique à Ortovero, près d’Albenga (province de Savone, Italie) en Ligurie occidentale qui peut être datée sur la base d’observations typologiques à la fin de l’Épigravettien ou au Sauveterrien. La matière première de l’ensemble lithique ressemble à celles des affleurements de radiolarite rouge de Ligurie orientale, bien que le nombre élevé de pièces réalisées sur ce matériau et la distance aux sources supposées nous amène à considérer cette hypothèse avec prudence. À la lumière des prospections de terrain conduites durant ces dernières années, les auteurs signalent l’existence d’un affleurement inconnu de radiolarites vitreuses rouges dans les environs du site, correspondant à la formation des « radiolarites d’Arnasco » qui affleurent non loin d’Ortovero.
