Archaeology: stone tools
Habitat comments: the matrix is 83% silt, 14% fine sand, and 2% clay and the environment is interpreted as an "open-air site" in a "suspension-loaded" floodplain
there are cutmarks and percussion marks plus toothmarks and other carnivore damage on the bones, and "butchery" is inferred while carnivore accumulation per se is not
