Life, Death and Teeth of Late Neolithic Sheep and Red Deer Excavated at Ness of Brodgar, Orkney Islands (UK)

The faunal remains from the late Neolithic site of Ness of Brodgar on the Orkney Islands (UK) provide a unique opportunity to investigate past adaptations of animal husbandry strategies to the Northern island environment, as well as the potential management of red deer. In this study, sheep and red deer mandibles and loose teeth (dP(4) & M-3) from the Ness of Brodgar were studied to construct age-at-death profiles, and analysed for delta C-13, delta N-15 and delta O-18. The mortality profile showed that around half of the analysed sheep were slaughtered when they reached maturity (i.e. after 2-4 years of life), consistent with a husbandry regime targeted at meat production. The stable isotope evidence indicates seaweed consumption in winter by several sheep (domesticates), but not by red deer (wild, possibly managed fauna). This dietary difference may have resulted from anthropogenically mediated influences, e.g. restriction of red deer habitats to upland areas. The varying extent of seaweed consumption between individual sheep and between Neolithic Orkney sites suggests differences in sheep husbandry practices across Orkney, indicating that the adaptation to consume seaweed was not ubiquitous on Orkney in the Neolithic, and did not follow a linear development.

Automated summary

The analysis of faunal remains from Neolithic Orkney revealed differences in animal husbandry practices between sheep and red deer, as well as potential anthropogenic influences on seaweed consumption behavior.
