Systematic re-examination of excavated material from comparable sites, using the methods that the COMMIOS team applied to Loch Borralie, might reveal additional cases that would allow the practice to be more fully characterized.

The specific questions that future work might address include: How widespread was the practice of post-mortem bone modification in Iron Age northwest Scotland?

Were specific social categories of individuals — by age, sex, status, or circumstance of death — more likely to receive this treatment than others?

Were the specific forms of modification (skull preparation, long bone whittling) consistent across different sites, or did they vary in ways that reflect regional or community-specific traditions?

And what is the relationship between these practices and the broader tradition of skull curation and human bone handling documented at other Iron Age British sites?
