Behrensmeyer Weathering Stages
Definition
A six-stage (0-5) macroscopic scale for characterising the degree of environmental weathering on bone, published by Anna Kay Behrensmeyer in Paleobiology (1978). Stage 0 is fresh with no cracking; Stage 5 is fully fragmented. Used in forensic contexts to estimate relative exposure duration and burial history.
- Scale range
- 6 stages (0 to 5)

Common questions
What is the Behrensmeyer weathering scale and what does it measure?+
It's a six-stage system (Stage 0 to Stage 5) that describes how much environmental weathering a bone has experienced. Stage 0 is fresh bone with no cracking, and Stage 5 is completely fragmented. Forensic examiners use it to estimate how long remains have been exposed and what their burial history might be.
When is the Behrensmeyer scale used in forensic investigation?+
It's especially useful for remains that have been exposed for extended periods well beyond the typical post-mortem interval window. It helps document long-term taphonomic changes and is part of the toolkit for assessing bone condition alongside other classification systems.
How does the Behrensmeyer scale relate to other bone examination methods?+
It works alongside systems like the Buikstra-Ubelaker inventory to create a complete picture of bone condition. While methods like the Megyesi Total Body Score focus on early decomposition stages, the Behrensmeyer scale picks up where those end, describing structural modifications from environmental exposure over longer timescales.
