Stable isotope values in tooth enamel were measured at the SSMIM (Paris, MNHN) with technical support of Joël Ughetto. Modern sheep mandibles and/or information on sheep herding practices on Orkney were kindly provided by Robert Mainland (Rousay), Linda Haganand Una Gordon (Holm of Aikerness), Billy Muir, Dr Kevin Woodbridge and the North Ronaldsay Sheep Court (North Ronaldsay). We would like to thank Anne Brundle, Tankerness House Museum, Orkney (Point of Cott), Dr Colleen Batey, University of Glasgow (Earl’s Bu) and ProfJane Downes and Nick Card, Orkney College, UHI (Mine Howe) for providing access to the archaeological mandibles. The authors would also like to thank Jane Outram and Mandy Jay for assistance in preparation and isotopic measurement of the vegetation samples, which were kindly collected by Robert Craigie, and Karen Chapman for preparing the mandibles. Lastly, the authors are also grateful for the constructive comments of the editors and anonymous reviewers.112562422engSDG 14 - Life Below Waterstable carbon isotopes (δ13C)stable nitrogen isotopes (δ15N)palaeodietary modellingseaweed-eating sheepprehistoric husbandrydairyingseaweed staggerPrehistoric husbandrySeaweed-eating sheepStable carbon isotopes (δ C)Seaweed staggerStable nitrogen isotopes (δ N)DairyingPalaeodietary modellingDEER CERVUS-ELAPHUSCOLLAGENStable nitrogen isotopes (delta N-15)DIETMARINERATIOSCARBONPAST HERDSStable carbon isotopes (delta C-13)TERRESTRIALEATING SHEEPNORTH RONALDSAYCC ArchaeologyQD ChemistryArchaeologyArchaeologyScottish Funding CouncilOtherNatural Environment Research Council (NERC)NER/B/S/2003/00223Supplementary DataCCQDJournal article10.1016/j.jas.2020.105140http://www.scopus.com/inward/record.url?scp=85083578155&partnerID=8YFLogxK118
