Bibcode:2011PNAS..108.8611P. doi:10.1073/pnas.1018938108. The direct date of the fossil (39,700 ± 1,100 14C BP) is in good agreement with the probability distribution function, indicating at a high level of probability that Neanderthals did not survive at Mezmaiskaya Cave after 39 ka cal BP. [...] This challenges previous claims for late Neanderthal survival in the northern Caucasus. [...] Our results confirm the lack of reliably dated Neanderthal fossils younger than ≈40 ka cal BP in any other region of Western Eurasia, including the Caucasus.{{cite journal}}: پارامەتری نەناسراوی |authors= چاوپۆشیی لێ کرا (یارمەتی)

"It was once thought we appeared in Europe around 35,000 years ago and that we coexisted with Neanderthals for thousands of years after that. They may have hung on in pockets – including caves in Gibraltar – until 28,000 years ago [said Chris Stringer]" Previous research on Neanderthal sites which suggested that they were more recent than 40,000 years old appears to be wrong," said Stringer. "That is a key finding that will be discussed at the conference."[...] However, scientists have set out to get round these problems. At Oxford University, scientists led by Tom Higham have developed new methods to remove contamination and have been able to make much more precise radiocarbon dating for this period.{{cite news}}: نرخەکانی ڕێکەوت بپشکنە لە: |accessdate= و |date= (یارمەتی)
