In Supplementary Table 1 of this Article, there were typos in the dating estimates of two samples, VK201 and VK203. In the ‘Age’ and ‘Finer_age’ columns both samples were listed as ‘Viking’ and ‘10th century CE’, respectively, whereas they should be listed as ‘Iron Age’, with finer estimates of ‘5–6th century CE’ (VK201) and ‘1–7th century CE’ (VK203). The Supplementary Information of the original Article has been corrected online.
