It appears, that they have found yet more pierced Nassarius gibbosulus shells in Grotte des Pigeons (near Taforalt, Morocco) during excavation conducted in March and April 2008. That would be 20 more shells, to be precise, which may be as old as 85,000 years BP, or slightly older than the ones Bouzouggar et al. (2007) published last year.
In 2007, Bouzouggar and Barton discovered 14 perforated shells in the same cave.
"This discovery shows that the making and use of objects of finery is very anchored in the traditions of Morocco's prehistoric people," said Bouzouggar, in whose opinion the country is the original centre of artistic and symbolic creation.
Objects of finery discovered in Morocco are "now considered to be even more ancient than those discovered in Algeria, South Africa and in Palestine", said the culture ministry.
Well, I don't know that these new finds do anything to establish that the practice of piercing and wearing shells is older in Morocco than it is at Skhul (ca. 100-135kya), but we can't say without seeing more information on the finds. From what I gather from a press release by the Moroccan Ministry of Culture (in French), this claim may be based on an assessment that the two shells from Skuhl cave (which I talked about here) "are difficult to date due to uncertainties about the context in which they were found," in part because they were recovered so long ago, in the 1930's. If you buy this, then the earliest shell beads would, in fact, be from Morocco.
The burials of five children dated to at least 12kya were also apparently found during the same field season. The children's remains were covered in ochre, buried under stone blocks with animal bones. Can't wait to hear more about these finds!
