title: Scavenging activity can produce predictable patterns in surface skeletal remains scattering: observations and comments from two experiments.
abstract: In forensic contexts, surface deposited remains are frequently found that have been scattered by various taphonomic processes. In an effort to develop strategies to improve recovery rates, this study evaluates whether patterns can be detected in the scattering of remains due to scavenger activity. In two experiments, 24 human analogues (pig carcasses) were placed in two adjacent but differing environmental contexts: 12 in wooded and 12 in open grassland. Six carcasses in each of these contexts were dressed in human clothing. Elapsed time and direction of movement information for each carcass and its parts were collected and analyzed. Unclothed carcasses and carcasses in open contexts exhibited scavenger activity sooner than the others. Scattering of remains occurred along game trails and was directed away from human population and activity. Due to the highly variable nature of scavenger activity, daily observations during a research project are the key leading to a better understanding of the development of these patterns.
