Nuevos yacimientos paleolíticos en la depresión de Monforte de Lemos (Lugo, Galicia, España)

This paper reports the discovery of new Paleolithic sites in the Depresion de Monforte de Lemos (Monforte Basin, NW of the Iberian Peninsula). This zone was filled with Quaternary deposits that have yielded 30 open air sites. Due to the casual discovery of Paleolithic artifacts a systematic archaeological work was carried out, assessing the archaeological potential of this area. Most of these lithic artifacts were found on surface, but also we have located two sites with archaeological materials in stratigraphic context (O Regueiral and Aspera). In the basin of Monforte we have recognized a human settlement along the Middle and Upper Pleistocene, with lithic implements classified as Mode 2, Mode 3 and Mode 4. The most important sites are As Lamas, Chao de Fabeiro (both with Mode 2 lithic industry, that includes handaxes and cleavers), O Regueiral (Mode 3), and Valverde (Mode 4). Thus the Monforte Basin has the adequate conditions to accomplish a diachronic study on the evolution of the strategies of technical behavior during the Paleolithic, and its relation with the evolution of Pleistocene environment.
