Paleofloristic data in the Nalon middle bassin between 40-32Kys. BP The "Cueva del Conde" anthracological analysis (Santo Adriano, Asturias)

Abstract

Anthracological data coming from the Cueva del Conde “Plataforma” excavation area, dated between 40-32 Kyr. BP, are presented in this work. Pinus sylvestris, Sorbus aria, Betula, appear as main arboreal taxa. Shrub stratum presents a great floristic variability coming from calcareous: Arbutus, Rhamnus, Crataegus, Prunus as well as siliceous substrats: Erica, Leguminosae (Ulex, Cytisus). Topographic characteristics of this area and discontinuity of substrats geographically closed, explain the proximity of these vegetal communities with diverse ecological affinities. Futhermore, the position of the cave in the middle part of the slope has made possible the alternative firewood management made among these vegetal communities by human groups that have seasonally inhabited this site.
