Protein residues were identified from zooarchaeological turkey (Meleagris gallopavo), rabbit (Leporidae), and squirrel (Sciuridae) remains from ancient pueblo archaeological sites in southwestern Colorado using a non-targeted LC-MS/MS approach. Results indicate that protein residues preserve well in tissues of origin, such as bone. Trace levels of protein residues from artifacts are more problematic to characterize because of poor preservation and due to several methodological challenges. ...

The identification of archaeological protein residues from cooking pottery using non-targeted mass spectrometry based approaches is a promising avenue of research. A major strength of mass spectrometry in archaeological protein residue analysis is that it allows for the reliability of protein identifications to be probabilistically quantified. Though it is clear that proteins can preserve in ceramics under favorable circumstances, little is known about diagenetic processes that affect...

This is an abstract from the "Bones and Burials in Philadelphia: The Arch Street Project’s Multidisciplinary Research" session, at the 84th annual meeting of the Society for American Archaeology. The Arch Street Project provided desiccated brain tissue recovered from a cemetery uncovered in Philadelphia, PA to the DeBusk College of Osteopathic Medicine Metabolomics Unit. As the Arch Street cemetery burials predate chemical fixation funerary practices, analysis of biological soft tissue...

This is an abstract from the "SAA 2023: Individual Abstracts" session, at the 88th annual meeting of the Society for American Archaeology. Organic residue analysis in archaeology using mass spectrometry (MS) is a robust technique to detect and explore ancient biomolecules for reconstructing past cultural behavior, such as diet composition and even specific recipes. Studies often involve targeted MS analyses of known or suspected substances, while untargeted analyses characterizing broad...

Residue preservation within the matrices of artifacts is a complex process that can be better understood when multiple types of biomolecules (e.g., protein and fatty acid residues) are evaluated as part of a systematic whole. Commonly, types of residues are evaluated independently, which may relate to different types of biomolecules requiring distinctive methods for extraction and analysis. Thus, the archaeologist either encounters positive results (a hit for a particular residue, such as a...
