Abstract
Lipid biomarkers play an important role in archaeological research due to their exceptional preservation over time and their potential to trace specific biotic sources. This makes them powerful tools for reconstructing past human activities and environments. In this talk, I will focus on my research on the Neanderthal site of El Salt in southeastern Spain, noted for its exceptional organic preservation and for holding over one hundred combustion features associated with recurrent human occupations between ~60 and 40 ka BP. These characteristics make El Salt a key locality for studying Neanderthal pyrotechnology. Here, I will present recent work exploring the potential of lipid biomarkers to determine the functionality of stone tools associated with these human occupations, through the characterization of lipids preserved along their edges that are detectable only at the molecular level. I will then discuss ongoing research that I am conducting at the ADAPt Lab (University of Alaska Fairbanks) in collaboration with Dr. Tammy Buonasera, focusing on lipid residues preserved in ash and black layers from Neanderthal combustion features at El Salt. This research aims to identify the functionality of different hearth types—such as pit and flat hearths—and to develop and assess novel methodological approaches for Palaeolithic sedimentary lipid analysis.
About the Speaker
Javier Davara is an archaeologist specializing in organic residue analysis and the study of the biomolecular archaeological record of prehistoric sites. His doctoral research focuses on lipid biomarkers preserved in stone tools and sediments from the Middle Palaeolithic site of El Salt (Alcoy, Spain). Through this work, he seeks to uncover how Neanderthal groups managed and used organic resources, while also deepening our understanding of the paleoenvironmental conditions of the site during the last glacial period.
