How can you distinguish scavenging modification from natural bone remodeling?

• A. Weathering alone
• B. Scavenging leaves tooth marks and irregular scoring on bone surfaces, with no healing, whereas natural remodeling occurs over time and is smooth
• C. Only human handling
• D. Magnetic field effects

Answer: (B)

Scavenging modification is detected by the pattern of alteration on the bone. Animals gnawing on a corpse leaves discrete tooth marks and irregular scoring on the bone surfaces, often with jagged, uneven edges and pits. Because this damage happens after death, there is no biological response to repair it, so you don’t see any healing or smooth replacement of the altered areas. Natural bone remodeling, by contrast, is the living bone’s ongoing process of resorption and new bone deposition that over time smooths and rounds surfaces. This produces a generally smooth, continuous surface rather than irregular, tooth-marked patterns. Weathering can roughen surfaces but doesn’t produce the distinctive tooth marks and irregular scoring seen with scavenging, and magnetic field effects are not relevant to distinguishing these processes.
