New methods on the block: Taxonomic identification of archaeological bones in resin-embedded sediments through paleoproteomics.

ABSTRACT: The integration of biomolecular studies of past organisms with geoarchaeological studies can significantly improve our understanding of the relative chronology and context of archaeologically (in)visible behaviors. However, the complexity and sedimentological heterogeneity of archaeological deposits at a microscopic scale is often not taken into consideration in biomolecular studies. Here, we investigate the preservation and retrieval of paleoproteomic data from bone fragments embedded in Pleistocene resin-impregnated sediment blocks. We show that resin impregnation has minimal effect on skeletal protein taxonomic identifications in modern skeletal material but observe an increase in oxidation of methionines. We then successfully retrieve proteins from resin-impregnated blocks from the Pal
