Sodmein Cave,Red Sea hills.

The chronology of the Middle Palaeolithic levels at Sodmein Cave
is difficult to establish,with a reasonable degree of confidence.
There was a fireplace in basal layer MP5,with a Nubian Levallois
core,that has a transversal pattern of preparation and a fragment of
a thin bifacially flaked tool.N Mercier et al [1999] obtained a
thermoluminescence average age estimate of 118 +/-8Ka for 6
pieces of burnt flint from two blocks [ibid].
The second oldest layer MP4 appears to represent a Nubian
Middle Stone Age [N-Group] industry,with Nubian points and
cores and a classic Levallois flake.These are overlain by tools,
that were manufactured with an emphasis on blade production,
that incorporated some Levallois components.Other lithic artifacts
include denticates,burins and Emirreh points [Andie Byrne,2007].
{Since the MP4 assemblages contain elements of mode 4
technology,the age of the cultural material could be significant}.
Mercier [1999] referred to C14 charcoal dates for MP3 and MP4
of greater than ca 48.48 Ka and greater than 48.05 Ka [cal’07].
However he did not provide information about the age of error
For the two age determinations,which appear to be near or above
the upper limits of the C14 technique.
The mode 4 tool industry at Boker Tachtit in the Levant has
tentatively been dated to 50.6 +/- 9Ka,cal’05.Any information
on this topic would be appreciated.
