Isotopic analysis doesn't allow us to pinpoint a person's place of origin, and O is particularly problematic: https://www.ncbi.nlm.nih.gov/pubmed/27124001
O and Sr isotopes can only tell us whether someone did not grow up in the area where they were buried.
Additional evidence, like genetics and forensic craniometry, can give clues about ancestry
Contrasted with burial practice picture gets complex and exciting re identity. You know this, of course, but I thought it worth restating.
Yes, def worth restating :) And reason for my scepticism re: using O to identify 'natives' vs 'Anglo-Saxon immigrants' in 5–6thC England! >
> Also yes, a fascinating paper! Agree, v tricky, esp if looking at main area of Europe; but argue slightly clearer w/ v high results tho >
> eg all results in post v high, above normal UK/Europe, w/ 21.0‰+ δ¹⁸Op from several individuals in post etc etc etc; also, all results >
> used in blog much higher than expected local results (3–10‰) plus mainly from Evans et al's eastern zone of lower levels etc, fwiw :)
Also in arid environments precipitation is less likely to be a source of drinking water than underground aquifers or rivers (Nile)..
Yes, absolutely. Fwiw, Nile comparison is to the tooth enamel results of ppl from Mendes burial site and others thereabouts, not precip O :)
