Summary of archaeological contexts of the human skeletal remains analysed in this study.
Fig 2.
Modelled Dorset and Beothuk radiocarbon dates.
Includes previously published dates from Raghavan et al. 2014 and Duggan et al. 2017.
Fig 3.
Calibrated Beothuk dates modelled with a date constraint of AD 1829.
The purple shaded bars specify the parameters used to model the radiocarbon dates. Where the skeletal remains were found with modified European artifacts or trade items, the dates were constrained between AD 1500 and 1829. Includes published radiocarbon dates from Duggan et al. 2017.
Fig 4.
The δ13C and δ15N values of Beothuk individuals.
The samples are separated chronologically by the median radiocarbon date of each sample. Includes published data from Duggan et al. 2017 and Kuch et al. 2007.

A comparison of the stable isotope values of Dorset and Beothuk adults and subadults.
The naturally mummified subadult, NP 240, is indicated by an arrow. Includes published data from Duggan et al. 2017, Raghavan et al. 2014, and Kuch et al. 2007.

Clusters of archaeological fauna used in the SIAR model.
The modern Newfoundland salmon data are from Dixon et al. 2012, and are corrected for the Suess Effect.
