Coímbre cave (Peñamellera Alta, Asturias) is an Upper Palaeolithic site in Northern Spain, spanning an occupation sequence from the Gravettian to the Magdalenian periods. The upper layers -layer I and II-, corresponding to the Upper Magdalenian, register the highest intensity of human activity. In this paper, we analyse raw material functionality at the site through the study of cut-marks found on bone remains. At Coímbre, we have documented mainly quartzite, followed by flint; other raw materials are found in very low frequencies. There are several types of local quartzite that appear mainly as flaking debitage and stone tools such as burins and scrappers. On the other hand, flint is mainly knapped to elaborate blades and bladelets, as well as specialised implements, such as different types of side scrappers. Retouched flakes on flint are relatively more abundant than those made on quartzite. In this paper we employ the use of photogrammetry, geometric morphometrics and statistics to analyse the cut-marks from the Upper Magdalenian assemblage of Coímbre cave. Our aim is to determine the lithic raw material preferentially used for carcass processing at the site.
