An area 255 m2 was excavated and 754 lithic pieces were recovered, as well as a large amount of micro and macro vertebrate remains, including proboscidean bones. The aim of this paper is to outline the results of the taphonomic study of these remains. The identification of cut marks on a number of the bones recovered strengthens the theory that the exploitation of extremely large mammals was more than just a marginal practice before the Upper Palaeolithic. Additionally, the identification of green-bone fractures and percussion marks confirm for the first time, that the bone marrow of these taxa was also consumed. Few other cases of this practice have been identified, firstly because obtaining this substance would not be an easy matter, and secondly because similar nutritional needs can also be met by the consumption of brain matter, which is easier to acquire.engjournal articlehttps://doi.org/10.1016/j.jas.2011.12.004https://cir.cenieh.es/handle/20.500.12136/507restricted access56(460.27)902(460.27)Cut marksPercussion marksProboscideansMiddle PalaeolithicIberian Peninsula.PaleontologíaArqueologíaPrehistoria2416 Paleontología5505.01 Arqueología5504.05 Prehistoria
