Unraveling the interplay between humans and carnivores in El Olivo Cave during the Middle and Upper Paleolithic period (Llanera, Asturias, Spain)

El Olivo Cave (Llanera, Asturias, Spain) is a small karst cave within the Aboño River watershed. It holds a significant archaeological and paleontological record dating from the Middle and late Upper Paleolithic, featuring several lithic artifacts and faunal remains in each archaeological level. The study of the faunal remains reveals a high representation of ungulates, with Cervus elaphus and Equus ferus being the main ones. Carnivores are also represented by diverse species such as Vulpes vulpes and Canis lupus, among others. The taphonomic analysis evidenced the presence of human activity, accompanied by a significant incidence of tooth marks across all stratigraphic units and water-related processes in the lower part of the sequence. During this temporal range, there were faunal accumulations of anthropogenic origin altered by the action of other agents, especially carnivores. A diverse array of carnivore used the same space and taking advanced of the anthropogenic residues as scavengers. Moreover, we suggest a commensal synanthropic behavior exhibited by foxes. Consequently, El Olivo Cave is an illustrative case to explore the carnivore action in levels with human presence, something unusual at the late Upper Paleolithic sites in Northern Iberia.
