Application of Protein Mass Spectrometry to Zooarchaeological Bone

Summary

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. Improvement of highly sensitive targeted LC-MS/MS approaches is an avenue for future method development related to study of protein residues from artifacts such as stone tools and pottery.
