- **Event Description**: Can Stable Isotopes Identify Individual Animals from Zooarchaeological Contexts? A Test Using Modern Cooper’s Hawks (Astur cooperii)

Authors: Jonathan Dombrosky, Miranda LaZar, Corrie Hyland, and Seth D. Newsome

Abstract: Zooarchaeologists often need to identify the remains of individual animals from highly fragmented and commingled assemblages, a problem that is both common and challenging. Biomolecular methods can help, but some, like ancient DNA analysis, are expensive or not always feasible. In this talk, we test whether stable isotope analysis can provide a more accessible way to distinguish individual animals. Using a collection of modern Cooper’s Hawks (Astur cooperii), we compare paired carbon (δ¹³C), nitrogen (δ¹⁵N), and hydrogen (δ²H) isotope values from muscle, liver, and bone collagen across 20 individuals. We explore how much isotopic overlap exists among individuals and whether machine learning models can correctly predict which samples come from the same individual. The results show high within-individual variability and substantial overlap, leading to low prediction accuracy overall. These findings suggest that identifying individuals from isotopic data alone is difficult, but that combining multiple isotopes and focusing on tissues that grow similarly may improve reliability.

Biosketch: Jonathan Dombrosky is Environmental Archaeologist at the Crow Canyon Archaeological Center. He received both his Bachelor’s and Master’s at the University of North Texas and his PhD from the University of New Mexico. He uses data science to answer broad questions about food-gathering practices and zooarchaeology in the central Mesa Verde region. Some of his major projects have focused on Ancestral Pueblo fishing strategies in the Middle Rio Grande region of New Mexico during the late pre-Hispanic period. He has wide-ranging interests in human behavioral ecology, stable isotope ecology, 3D geometric morphometrics, radiocarbon chronology building, and conservation biology.
