@farmerman,
Ill wager that the radiocarbon date will be around 8 to 8.5 X10^3 ybp.
That number is a unique stadial value from lots of Siberian megafossils. (The number needs to be more closely assessed because theres a few radiocarbon "plateaus" in the Siberian/Kamchatka/E Siberian Sea areas. Reasons for these are still being chased down but it seems at least to correspond to some huge "wet gas" shale deposits .
