Siberian Princess reveals her 2,500 year old tattoos

The ancient mummy of a mysterious young woman, known as the Ukok Princess, is finally returning home to the Altai Republic this month.

Those tattoos look surprisingly modern.
Khantys and Mansis also used to wear clan tattoos, and it seems to have been quite common in Siberia.

I found this quote quite interesting:
'The people of Pazyryk belonged to different ethnic group, in no way related to Altaians. Genetic studies showed that the Pazyryks were a part of Samoyedic family, with elements of Iranian-Caucasian substratum.'

To what extent is "Samoyedic" a genetically definable group, or do they perhaps refer to eg. the Sayan Samoyeds only? And is this supposed to carry any linguistic implications?
