Locating Proto-Uralic

[Jaska]

"At this point, the absolute chronology can only be estimated very roughly. ProtoWest Uralic can be located around the Upper Volga–Oka fork in the mid-second millennium BC (Häkkinen 2009: 37–40; Kallio, forthcoming), to where it arrived from the east."

"Common West Uralic probably dates in the centuries around the beginning of the first millennium BC, spreading to the south and west to the Upper Volga–Oka Region. Here the contact language was Archaic Balto-Slavic and towards the end also ParaSlavic and the early stage of East Baltic."

Fatyanovo is dated 2900-2000 BCE at best. How can you prove Baltoslavic in Fatyanovo using evidence from 1500 BCE or 1000 BCE when Fatyanovo got replaced by post-TCC people in Russia? 

So, is there a linguistic evidence from 2000 BCE BaltoSlavic in Fatyanovo? If no, then in case of absence of linguistic evidence, genetics and archeology should be used.

I never said that Proto-Balto-Slavic was spoken within Fatyanovo. Only its ancestral stage. Please read my comments before you reply to them.
