experimental line with wild animals in the Catalan Pyrenees, whose objective is to simulate scenarios to model and characterize the actions of large and small carnivores, and extrapolate the results obtained at European Pleistocene archaeological sites. The variety of agents and processes that can potentially act during the reservoir formation process is wide. However, the biological accumulators par excellence are hominids and carnivores. Both predators intervene on animals with the same nutritional purpose and, therefore, some of the evidence left in their wake is similar. To this must be added that both hominids and carnivores can share the same habitable spaces (caves or shelters),

even going so far as to intersperse their Barbados Email Lists occupations almost immediately. This phenomenon sometimes generates an amalgam of overlapping events, or palimpsests, which makes archaeological interpretations difficult or complicated to varying degrees. Due to this, it is necessary to characterize the actions of both predators and find diagnostic elements that differentiate them, both at the level of bone modification, and of alteration at a spatial level, that is, of the dispersion of remains. Experimental series Actualist studies based on observation and experimentation are a fundamental tool to characterize and model the predatory behaviors of wild carnivores. “The characterization of their behavior in controlled scenarios will allow us to extrapolate their actions to the archaeological level,

allowing us to isolate more safely the events starring carnivores and hominids, and therefore deepen the interactions that both predators could have in the form of competition by the prey, confrontation and / or dependence, in the sense of scavenging ”, explains Ruth Blasco. The experimental series, which involve both large carnivores, such as the brown bear, and small carnivores, for example the fox or the badger, have been developed mainly in the Lleida Pyrenees, especially in the Parc Natural de l’Alt Pirineu, where there is no human conditioner that can alter the behavior of animals. “This circumstance is vital when extrapolating the experimental data, since the studies that have been carried out with carnivores in captivity or semi-freedom could run the risk of reflecting alterations
