Environment
Lithology: claystone
Taphonomic context: cave
Archaeology: stone tools
Habitat comments: the C complex is "composed of red colluvial sandy clays... as well as blocks and rocks detached from the cave walls" (Michel et al. 2008)
the entire C sequence is interpreted as a "Homo erectus" or pre-Neanderthal occupation based on a final Acheulian-age lithic industry rich in bifaces, but accumulation agents per se are not discussed
