Dear Thomas!
In 1984 I worked with archaeologists in expedition. Human bones (which
were buried from 45 to 5 centures ago) was selected from 7 barrowes
of nomads. Content of SO4 (mg per 1g of bone material) changed from
15,3 to 41 and sulfur isotope composition from 7,6 to 8,9 %. . This
data was not published.
Hope this help you
Sergey.
