Re radiocarbon dating: the usual upper limit of applicability is about 40-50,000 years, but I wouldn’t want to rank the reliability of a C14 date based on its age in millennia – more on how recently it was processed. There are LOTS of wrinkles. Uptake from marine sources or volcanic eruptions can skew the results. Contamination can be an issue, as can the lab doing the work. Then there’s the “old wood” problem – is the date you’re getting related to the artifact being dated, or the material it’s made of, which may have stopped uptake of atmospheric C14 years or centuries before it was used. Calibration and some stunning new techniques are improving the reliability hugely, but it’s critical NEVER to assess a radiometric date without taking its archaeological context into account.

The calibrated dates Martin uses for his Paleolithic paper are very beautiful dates indeed for the most part, but the archaeologists involved chose their sample with a completely different set of archaeological problems in mind. His test is pretty much a textbook case of the misuse of perfectly lovely archaeological data, dragged kicking and screaming out of context.
