Jacques, is there a preliminary link you can post?

I went looking, but couldn't find anything.

Whoops, just found the highlighted link. Didn't see it before. ??

HERE we go again with a new variation on a well-known theme, a process that goes by the name of "paradigm shift".  Whether or not this is turning into a bad Hobbit, I don't really know. I guess, I'll have to read the actual JHE article in order to make up my mind and come up with more serious comments.

For those that have access to the Texas Archeological Society Bulletin there is a very interesting 40 page site report "An 18,000 Year Old Occupation Along Petronila Creek in Texas" by C.R. Lewis. This site in Nueces County has broken mammoth bones with cut marks with a 14C date of 18180+/-330BP as well as numerous other species represented. One of the unique features of the site is the presence of broken mammoth molars which were used for pounding and grinding, some even showed facets from use. However the most unique feature of the site is thousands of rodent teeth, many broken and about 35% acid etched recovered from what the author termed "latrine lenses". His interpretation was that these people were pounding the skulls of rodents (mostly prairie dogs) into a mush for consumption.

The author also discusses several lines of faunal evidence that indicate the site could possibly be as old as Sangamon interglacial.

Thanks Jean-François,

André Langaney makes a similar suggestion about population size as a possible reason for the extinction of Neanderthal. A smaller population becomes more vulnerable to inbreeding and all the problems that arise through it.

Then the question is why did Neanderthal population begin to shrink at a certain point?

I can't remember where I read some hypothesis about a possible contamination of Neanderthal by germ carried by Modern human, somewhat like "white men" transmitted "Old World" germs to Native Americans, which caused terrible epidemics among them.

It will probably be very difficult to settle this debate on Neanderthal's disappearing.

From Pierre Francois Puech:
The number, not competition, not climate, killed Neanderthals. The number allways win in population competitions, it has been the case for neanderthals opposed to anatomically modern humans. Studies of dental microwear of Zafarraya neanderthal from southern Spain (30-27, OOO BP) compared to the success neanderthal large group that occupied, 50,000 BP, the site of Hortus (south of France) has provided evidence that no changes occured in the way of life inferred from the menu (Puech P. -F. Usure dentaire, In “La Grotte du Boquete de Zafarraya” Barroso R. and Lumley (de) H. eds, Junta de Andalucia, Consejeria de Cultura, Sevilla.)
A free "pdf" in French, concerning Zafarraya dental microwear, is to be asked to

There is an informative article on marine shell dating by Fiona Petchey titled "Dating marine shell in Oceania:Issues and prospects",2009.

Just for info, i received this through"Newswise.
California's Channel Islands Hold Evidence of Clovis-age Comets

Newswise — A 17-member team has found what may be the smoking gun of a much-debated proposal that a cosmic impact about 12,900 years ago ripped through North America and drove multiple species into extinction.
In a paper appearing online ahead of regular publication in the Proceedings of the National Academy of Sciences, University of Oregon archaeologist Douglas J. Kennett and colleagues from nine institutions and three private research companies report the presence of shock-synthesized hexagonal diamonds in 12,900-year-old sediments on the Northern Channel Islands off the southern California coast.

I won't comment since this isn't my field of interest...
