Revealing the invisible dead: integrating bio-geoarchaeological approaches in an apparently "empty" Viking-Age equestrian burial

Conference 26 - 27 May 2022 Microarchaeology: making visible the invisible archaeological record through high-resolution integrated approaches Coordination: Marta Portillo (IMF-CSIC), Aroa García-Suárez (IMF-CSIC), Juan Francisco Gibaja (EEHAR-CSIC) & Antonio Pizzo (EEHAR-CSIC)In 2017, a team of archaeologists and specialists investigated the apparently empty and partly disturbed Viking-Age equestrian burial of Fregerslev II, Denmark. This did not only provide a once in a lifetime opportunity to excavate such an elite grave, now with much more modern techniques than during earlier excavations of similar graves, but also to develop a novel multi-scale and multi-method analysis of burial and post-burial processes. To overcome the limitations of poor preservation and the lack of a clear macrostratigraphic sequence, multi-proxy analyses of organic and inorganic materials were combined to study the burial and its spatial organization as well as post-depositional processes. Techniques applied includedsoil chemistry (inductively coupled plasma mass spectrometry - ICPMS, portable X-ray fluorescence spectrometer - pXRF), soil micromorphology, analysis of faecal lipid biomarkers and analysis of wood, botanical macroremains, phytoliths, pollen and non-pollen palynomorphs. This presentation will present the highlights of the results of the various analyses, showing the potential and relevance of integrating high-resolution approaches for the analysis of poorly preserved burial contexts
