This comparison would not be definitive — cranial morphology assessment from photographs has significant limitations — but it might provide additional circumstantial information about whether the skull in the photograph could plausibly be Geronimo’s.

The photograph’s current location, and whether Anderson retained it or a copy, is not established in the public record.

What DNA Testing Would Actually Look Like

If DNA testing were to be conducted in the Geronimo skull case — if Skull and Bones were to allow examination of any relevant remains, or if the grave at Fort Sill were to be examined — what would the testing process actually involve?

The first step would be sample collection: extracting material from the tooth or bone for genetic analysis.
