Today they discuss García Borja 2010 (Zephyrus), which deals with the important Andalusian site of Nerja cave. According to García, the reference C14 dates (uncalibrated) are:
- 10860 ± 160 BP and 10040 ± 40 for Epipaleolithic (microlaminar or Azilian, NV-4)
- 7610 ± 90 and 7240 BP for a transitional phase (NV-3), dominated by a hunter economy
- 6590±40 BP in a sheep bone from NV-2 (but intruding by means of digging into the NV-3 zone)
The mine was previously mentioned, in greater extent, here.
Update (May 26): in the comments’ section it was mentioned that another, no so old, quarry is known to have existed in Virginia, where the first inhabitants extracted red jasper. The site is dated to c. 10 Ka BP and you can read about it here and (if you have a Science subscription) also here.

Important update (May 27): Other possible populations with A1b
Argiedude believes that he had identified A1b lineages in a number of populations (based on other studies and using mostly STR haplotype sequences). He included this spreadsheet (should be available for a year) where the likely A1b individuals were identified by him as “A4”. See the commentaries for further details.
The populations with possible A1b are therefore expanded from just two (Bakola Pygmies and Mozabites) to several, with a peak of frequency in Southern Ghana. Also in Gabon, SE Nigeria and Cameroon, and as isolated individuals in Zambia, Ivory Coast, Burkina Faso (and then, of course, across the Atlantic in America).

|Yellow lines outline the deserts of Arabia, Nefud being at the North|
Major hydrological variations associated with glacial and interglacial climates in North Africa and the Levant have been related to Middle Paleolithic occupations and dispersals, but suitable archaeological sites to explore such relationships are rare on the Arabian Peninsula. Here we report the discovery of Middle Paleolithic assemblages in the Nefud Desert of northern Arabia associated with stratified deposits dated to 75,000 years ago. The site is located in close proximity to a substantial relict lake and indicates that Middle Paleolithic hominins penetrated deeply into the Arabian Peninsula to inhabit landscapes vegetated by grasses and some trees. Our discovery supports the hypothesis of range expansion by Middle Paleolithic populations into Arabia during the final humid phase of Marine Isotope Stage 5, when environmental conditions were still favorable.

- Petraglia 2010 (accessible at Scribd) which extensively analyzes occupations Middle Paleolithic occupations in Arabia and South Asia
- Bailey 2009 (Lower and Middle Paleolithic in Arabia peninsula) and Rose 2010 (Persian Gulf, then firm or swampy land, oasis). Both discussed here along with Fields 2007 on modeling migrations across South Asia.
