Rapid climate change in the Upper Palaeolithic: the record of charcoal conifer rings from the Gravettian site of Dolni Vestonice, Czech Republic

Precisely how Upper Palaeolithic human ecology was shaped by changing climate during the Pleniglacial remains a matter of debate, for while this generally cold period is now understood to include complex and often rapid flux in climate, there are still considerable difficulties in resolving climatic variations at particular times and places - derived from various lines of proxy evidence - with the high-resolution proxy record of temperature changes from oxygen isotope analysis of the Greenland ice-cores. In this paper we apply the methodology of large-scale flotation to newly excavated contexts from the Upper Palaeolithic (Gravettian) site of Dolni Vestonice II, Czech Republic, to explore the potential of charcoal - as a natural archive of environmental information - to offer information on environmental change towards the end of the middle pleniglacial during Oxygen Isotope Stage 3, between c. 32,500 and 31,200 Cal yr BP. The results of an analysis of ring widths and other anatomical features - interpreted alongside micromorphological data - indicate that this charcoal may capture a higher-resolution record of the changing climatic conditions during which humans were first expanding into these hitherto marginal ecologies and, consequently, shed new light upon the complexity of the lifeways that enabled them to do so.
