Strontium isotope composition of teeth and other skeletal elements can be used to identify the geographic region that an animal or human inhabited, because different regions tend to have distinct Sr isotope compositions, and natural variations in the relative abundance of Sr isotopes are not changed as Sr is processed through the food chain. Therefore, an organism that ingests Sr from one region can have a Sr isotope composition that is different than that of an organism that ingests Sr from another region.

Says that vikings filed their teeth for ‘beautification’. Not stated in the article being commented on, but interesting bit of information.
sounds all fine and dandy but the article says one individual has the composition of someone from north of the arctic circle.
That’s BS! there’s never been vikings from north of the arctic! That’s saami land and eskimo land and samoyed land.
no vikings.
