Stable sulphur isotope data for the faunal samples are presented in Table 2 and Figure 2.
The total range for the marine mammals is from +13.6 to +16.0‰ (mean +14.8, sd 0.8‰, n=6), including harbour porpoise (+14.8 ± 0.6‰, n=3), ringed seal (+14.1 ± 0.7‰, n=2) and one harp seal (+16.0‰). The only analysed specimen of fish, a marine garpike, has a somewhat higher value of +17.3‰ (but see reasoning above). One unidentified marine bird (as inferred from its carbon isotope value), has a considerably lower δ34S of +8.4. One red fox, which had a mixed marine/terrestrial diet, has a slightly higher value, +9.5‰.
Wild terrestrial species vary between +6.6 and +13.6‰ (+10.0 ± 1.9‰, n=13). These include moose (+11.4 ± 0.8‰, n=3), one roe deer (+8.7‰), one pine marten (+10.6‰), the mountain hares, which range from +7.8 to +13.6‰ (+10.4 ± 2.1‰, n=5), and the pigs from Köpingsvik (+8.2 ± 1.4‰, n=3). The Köpingsvik pigs were interpreted as wild/feral due to the lack of correspondence between human and pig δ13C and δ15N values, indicating that these animals did not feed on human food waste to any detectable extent (see further discussions on PWC pigs in Eriksson 2004; Fornander et al. 2008).
Cattle and sheep/goat range between +5.8 and +11.0‰ (+8.1 ± 1.9‰, n=7), whereas the two (possibly domestic) pigs from Resmo have values of +2.1‰ and +7.3‰, respectively. Dogs fall into two dietary groups, based on carbon isotope data. The two terrestrial dogs have uniform δ34S values (+7.5 ± 0.3‰, n=2), whereas the dogs feeding off marine resources have a wider range, from +12.1 to +15.7‰ (+13.9 ± 1.5‰, n=5).
