The goal of this project was to develop regionally specific standards for taphonomic (postmortem) data collection and interpretation in northern New England, to be used in the recovery and interpretation of human skeletal remains. The objectives included analysis of a 30-year outdoor case series and controlled observational studies of nine pig (Sus scrofa) cadavers to illuminate key components of the model. List of Tables.
