Scavenging Artefact
Definition
Marks, wounds, or tissue removal caused by animals feeding on a body after death. Scavenging artefacts can alter or destroy existing wounds including genuine bite marks, and can create new patterned injuries that superficially resemble ante- or perimortem wounds.
- Cause
- Post-mortem animal feeding activity
- Risk
- Can mask or destroy genuine bite marks
- Also
- Can mimic ante- or perimortem patterned injury
- Discipline
- Forensic odontology and taphonomy
Common questions
How does an examiner distinguish scavenging from an inflicted wound?+
Scavenging tends to produce irregular tearing, tooth-drag striations, and tissue loss concentrated at exposed extremities, without the vital reaction seen in wounds inflicted before death, though overlap cases require careful histological and pattern comparison.
Why does scavenging complicate bite mark evidence specifically?+
Animal feeding can obliterate or overlay a human bite mark on the same tissue, and animal tooth spacing can superficially resemble human dentition, so an examiner must rule out scavenging before treating a mark as evidence of human origin.
