Panels showing the Δ13C (δ13C18:0-δ13C16:0) proxy for the different studied economic groups. (a) Coastal agrarian groups using dairy and marine products, (b) coastal hunter-gatherers, with a diet based on marine mammals and fish, and (c) interior hunter-gatherers with a diverse food procurement pattern consisting of terrestrial animals and fresh water fish. The organic residues from vessel plotting to the RHS contained a greater marine component compared to those plotting more to the LHS. The stars represent lipid residues that contained biomarkers of marine/aquatic origin, and the circles represent the fats that originated from terrestrial resources. The grey rectangles indicate the range of δ13C16:0 values of modern Eurasian elk fats (on the left) and reindeer/wild forest reindeer fats (on the right)49.
