##  [Taphonomy](/taphonomy-0) 

 Definition

The investigation of physical, chemical and biological processes acting on organic and inorganic remains from the moment of death or deposition through transport, modification, burial and recovery, aimed at identifying signatures of alteration, agents of change and conditions of preservation.

 

 

 

 

 

 





## Principle

Principle

Taphonomic signatures (weathering, abrasion, gnawing, cut marks, dissolution, mineral replacement, microstratigraphic alteration) record the agents and pathways of modification; interpreting assemblage integrity and causation depends on diagnosing those signatures.

 

 

 

 

 





## Demonstration

Demonstration

Illustrative scenario → A bone assemblage shows linear striations and percussion fractures plus tooth pits on cortical surfaces. Recognition → Analyst records distribution, orientation and micro‑morphology of marks. Action → They attribute some marks to butchery (cut marks) and others to carnivore gnawing, and separate human‑modified elements from scavenger‑modified ones when inferring subsistence behavior. Consequence → Subsistence interpretations are constrained to elements demonstrably modified by humans.

 

 

 

 

## Misapplication

Misapplication

Attributing marks or breakage patterns to human activity without a comparative taphonomic framework. The error is conflating superficial resemblance with diagnostic evidence and ignoring alternative natural agents.

 

 

 

 

 





## Consequence

Consequence

Appropriate taphonomic analysis refines which parts of an assemblage reflect human behavior versus natural processes, improving behavioral, depositional and preservation inferences; inadequate taphonomic assessment risks false claims about human agency, seasonality, site use or mortuary practice.

 

 

 

 

## Reversal

Reversal

In contexts with exceptional preservation (e.g., anoxic waterlogged sediments, desiccation, rapid burial) many taphonomic processes may be suppressed, so absence of expected alteration does not automatically indicate lack of exposure or handling—contextual preservation conditions must be considered.

 

 

 

 

 





## Boundary

Boundary

Clearly within: study of alteration signatures on biological remains, lithic edges, ceramics and other materials from deposition to recovery. Boundary case: weathered surface artifacts where distinguishing pre‑ vs post‑depositional surface alteration requires microanalysis. Clearly outside: purely typological classification that does not assess post‑depositional change.

 

 

 

 

 





## Semantic Tension

Semantic Tension

Taphonomy ↔ Cultural Interpretation: taphonomic evidence constrains behavioral inferences but may also be used to argue for behavioral causation; balancing conservative attribution of agency with interpretive claims is a recurring tension.

 

 

 

 

 





## Synthesis

Synthesis

Taphonomy supplies the diagnostic criteria needed to separate residues of past human action from overprinting natural processes: it is the methodological bridge between material condition and reliable behavioral inference.
