Figure 3.

Distribution of mediaeval European finds of walrus rostra, showing the proportion of roughly facetted (type 2 or 3) and unsculpted (type 1) examples in each location. Potential mediaeval trade routes are also shown. Stars mark the locations of control samples from Greenland, Iceland, Finnmark and Svalbard. The modern distributions of the eastern and western genetic clades of Atlantic walrus are shaded. In previous times, walruses were also found as far west as the Hammerfest area in Finnmark, around Iceland, and as far south as the former Western Settlement in western Greenland.
