Research Council of the United Kingdom. Investigative team The work has been directed by Pau Carazo and carried out in collaboration with researchers from the University of Oxford. Carazo is currently the director of the Behavior and Evolution Lab group (http://paucarazo.com), which belongs to the Ethology unit of the Ecology, Ethology and Evolution group of the Cavanilles Institute of Biodiversity and Evolutionary Biology. The group is currently made up of three doctoral students, a laboratory technician and Pau Carazo. His lines of research include the evolution and function of sexual conflict and aging, and the role of behavior in evolutionary change. Ruth Blasco, specialist in Taphonomy at the National Center for Research on Human Evolution (CENIEH) leads a new experimental line with wild animals in the Catalan Pyrenees,

whose objective is to simulate Western Sahara Email Lists 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 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,
