Odintsovo culture (Altai Krai region)
Odintsovo was an Iron Age culture in Altai Krai region, which spoke unknown languages. Major paternal lines were R1b-L1432.
The autosomal ancestry seems to be Eastern Scythian + local Siberian (WSHG-riched) type ancestries.
Srostki culture (from 8th century onwards)
Since cold war era, the Soviet archeaologists linked Srostki to the Kimaks and Kypchaks. with the WGS data from Srotski, this idea seems to be proven. about a half of the Srostki males as well as a large number of the unpublished Kypchak samples carry Odintsovo-related R1b-L1432, a paternal line that appears to have been a dominated Y-DNA in Kypchak-Kimak union. interestingly, most of modern "Kipchak clan" of the Kazaks also carry this exact subclade. the Kypchak-Kimak union also had considerable amount of J2a-PH1795 from their Altai Shaz Turkic progenitors.
