Abstract

La Güelga cave is located at the bottom of a mountain valley in the Eastern part of Asturias (Northern Spain), 186 m above sea level and 15 km far away from the coast. It currently comprises a group of caves that were occupied during the Middle and Upper Paleolithic periods (MP and UP respectively). In recent years, we have studied the levels of La Güelga cave –D Zone-proposing a sequence for the MP/UP transition: Mousterian-Aurignacian-Châtelperronian, which we review in this paper after a detailed analysis of the chronostratigraphy. We also provide new radiocarbon dates for the Mousterian, Aurignacian and Châtelperronian levels. Finally, the geoarchaeology, taphonomy, archaeological data, and chronology suggest that the interstratification -initially identified on the basis of stratigraphic observations during excavation-cannot be maintained. In any case, the stratigraphy of the internal D Zone of La Güelga cave is one of the most interesting from the Cantabrian region for analyzing the last phases of the Mousterian and the rise of the Aurignacian in the North of the Peninsula.
