San Francisco de Borja is a cave-shelter burial site located in Chihuahua, Mexico, that was excavated in the 1950s by Richard and Sheilagh Brooks and is now curated at UNLV. Human remains collected from this cave site include male, female and juvenile individuals dating from the late prehistoric period. This project documents and analyzes the wide range of taphonomic processes that have affected these remains. These processes include perimortem chop marks, surface bleaching and burning. Based on these observations, violence and partial cremation of some individuals is suggested.
