Collagen and Apatite Stable Isotope Values from Bison Bone at the Hell Gap Site
Author(s): Tony Fitzpatrick
Year: 2021
Summary
This is an abstract from the "SAA 2021: General Sessions" session, at the 86th annual meeting of the Society for American Archaeology.
This work adds collagen δ15N and δ13C to the apatite δ13C and δ18O values previously presented by the author, as well as C:N ratios demonstrating the viability of many samples from Hell Gap. Bison bone can be found throughout Paleoindian deposits at the site, providing a possible proxy for regional climate change. Carbon ratios for collagen samples (n=23) range from -19.08% to -14.60%, and apatite, which is currently a smaller subset of samples (n=13), from -9.4% to -6.5%. Apatite-collagen spacing of carbon is between 8% and 10.41%, with an average of 9.23%. Apatite δ18O values range from -10.2% to -8.0% and collagen δ15N from 5.15% to 10.62%. These data are compared with existing paleoclimate information from Hell Gap and the surrounding area.
