Previous research of 87Sr/86Sr variability in human dental tissue from the Nile Valley has shown diversity in bioavailable strontium across the landscape. Local ranges, determined from faunal sampling, have been suggested for several sites in Nubia, including Tombos (Third Cataract, Sudan). This study builds on previous research by testing human and faunal dental enamel samples from three sites in the Third Cataract region: Tombos, Hannek, and Abu Fatima. The addition of Abu Fatima and Hannek into the assessment of the Third Cataract region brings new temporal and socioeconomic juxtapositions that can shed light on migration and locality in Bronze Age Nubia.Two faunal samples, a sheep from Abu Fatima and a horse from Tombos, had 87Sr/86Sr values that were consistent with the previously established local Third Cataract strontium range. Seven of the 29 human samples tested for Abu Fatima are suggestive of non-local origin and consistent with the Second Cataract region. One of the four individuals tested from Hannek may have migrated to the region from Egypt or the Second Cataract region. Lastly, four of the 30 samples from Tombos indicate possible non-local origin; the 87Sr/86Sr values may suggest Egypt, the Second Cataract, or the Fourth Cataract as places of origin. These findings suggest complex human migration networks were present in the Nile Valley during the Bronze Age. We support the continued examination of migration using strontium while acknowledging that further research needs to be done.
