Our interpretations of British prehistoric deposition practices have been greatly influenced by classical sources and inherited wisdom. However, with the expansion of artefact databases, reanalysis is required to reconsider what is known about wetland deposition in relation to British Iron Age activity. To do so, we must understand how archived physical evidence has been interpreted, and as a result, created certain biases in modern understandings. This paper proposes the use of amalgamated object records to refine British Iron Age wetland depositional traditions in Wales and Scotland.
