late pleistocene population interaction in western europe

Approximately 5 % of the EJOP décapages have been reattributed to more precise
stratigraphic units based on this method. The remaining units (80% of the décapages)
were studied according to their initial attribution.
For the EJO level, only 1% of the assemblage has been reattributed to either
EJO inf or EJO sup following a similar procedure. Regarding the other levels of the site,
few modifications were made. Square G4 was deleted from the Aurignacian I (EJF) and
the Evolved Aurignacian EJM samples because of stratigraphic problems. In addition,
forty-two décapages (approximately 2.5% of the total) were removed from the samples
due to a lack of data concerning provenience or discordant stratigraphic information.
Lastly, décapages that include materials from more than one layer were ignored in this
study.
Certain stratigraphic units have not been detected in some squares, principally in
lines 6 through 9 where the layers are thin. In addition, heavy machinery truncated lines
B and C, particularly in the most recent levels. Squares concerned by these problems are
not included in the density maps and have been deleted from most counts. However,
taxonomically identified bones recovered in these squares were included in this study.
The very rich EGPF level, the most recent Mousterian occupation of the site, has not
been entirely studied yet and only a sample could be included in this study. This sample,
limited to the uppermost décapages, represents approximately 15% of the faunal material
of the EGPF level.
