What changed in the quarter-century between the initial analysis and the re-examination was not primarily the evidence itself — the bones are the same bones — but the analytical methods available to examine that evidence and the interpretive frameworks available to contextualize the results.

The development of more precise taphonomic analysis, the advancement of ancient DNA extraction and sequencing methods, the refinement of isotope analysis techniques, and the accumulation of comparative evidence from other Iron Age sites across Britain all contributed to the COMMIOS team’s ability to see things in the Loch Borralie remains that the original analysts could not.

This lesson — that archaeological collections in storage may contain information that cannot currently be accessed but that future methods may reveal — is one of the most practical implications of the Loch Borralie study.

It is an argument for the careful maintenance of archaeological collections, for the documentation of material that cannot currently be fully analyzed, and for the periodic re-examination of stored material as methods advance.
