At www.livescience.com/52700-mysterious-geoglyphs-in-kazakhstan-revealed.html … it seems the New York Times date of 8000 years ago may not be up to scratch. Live Science asked the three Russian archaeologists quoted and they said the only dates they were aware of were 800BC – produced by thermo luminescence dating methodology. Live Science were a bit sceptical of the 8000 years ago date but this appears to have been derived by somebody thinking there was a connection with a local culture extent between 7000 and 5000BC. If that is true and then the 8000 years ago tag is relevant – but the archaeologists are not convinced. So where did the New York Times get its story?
