Human behaviour and adaptations to MIS 3 environmental trends (>53–30 ka BP) at Esquilleu cave (Cantabria, northern Spain)

Esquilleu cave (Cantabria, northern Spain) presents 30 Mousterian archaeological layers covering virtually the complete MIS 3 both in chronology and environmental. A number of environmental analyses (faunal, pollen, charcoal) allow the study of the different strategies for the procurement and management of resources available near the site and indicate the Neanderthals’ wide adaptability to the changing environment typical of this period. This paper also discusses the possibility of using bones as fuel either as a palliative for a presumed lack of wood resources in the environment or as a mere pattern of human behaviour.
