The archaeological investigations carried out in the last twenty years in the Lower Valley of the River Güeña (Asturias, central part of northern Spain) have documented different prehistoric sites, particularly with Middle and Upper Palaeolithic occupations. This paper presents the first results of the archaeological excavation carried out in the cave of La Cuevona de Avín. From the systematic study of the biotic and abiotic remains, a total of three occupation phases (Phases 1 to 3) have been determined, dated in the Late Pleistocene. The lithic studies indicate the use of local raw materials (mainly quartzite), but also regional ones (different types of flint) in the whole sequence. Retouched implements are typologically representative only during the Upper Magdalenian (Phase II) and use-wear analysis indicates the manufacture and use of artefacts in situ during this phase. Archaeozoological studies reveal continuity in subsistence strategies throughout the sequence, noting specialization in red deer hunting during the Azilian (Phase I), and more diversified prey in the older phases of the sequence.

过去 20 年在 Güeña 河下游谷地（西班牙北部中部的阿斯图里亚斯）进行的考古调查记录了不同的史前遗址，特别是旧石器时代中期和晚期的占领区。本文介绍了在 La Cuevona de Avín 洞穴中进行的考古发掘的第一个结果。通过对生物和非生物遗迹的系统研究，共确定了三个占领阶段（阶段 1 至 3），年代为晚更新世。岩石研究表明在整个序列中使用了当地原材料（主要是石英岩），但也使用了区域原材料（不同类型的燧石）。在这个阶段就地。考古动物学研究揭示了整个序列的生存策略的连续性，注意到在 Azilian（第一阶段）期间猎杀马鹿的专业化，以及在序列的较早阶段更多样化的猎物。
