Exploring methods by which to quantify confidence in canid species determination Abigail E. Fisher and Ian Jorgeson Abstract: Due to their ubiquity across North America, dogs have the potential to inform on a variety of human behaviors. Dog skeletal remains, however, are particularly difficult to identify in archaeological assemblages due to their fragmentary nature (a product of life history and taphonomic processes) and similarity in morphology and size to wild canids such as coyotes and wolves. This research uses geometric morphometrics to better classify canid remains. While most methods of species differentiation result in an absolutist identification, we are developing a probabilistic model relating morphological variation to species likelihood. As a probabilistic model, our approach will both identify the most likely species represented by a sample, and quantify the uncertainty of that classification. Problem: Dogs remains have the potential to provide insight on pa...
