Geography
Country: Algeria
Coordinate: 36.204102° N, 5.627° E
Coordinate basis: stated in text
Formation: Ain Boucherit
Time interval: Early Pleistocene
Section: Ain Boucherit
Unit number: 2
Unit order: below to above
Ma: 1.92
Age basis: ESR
Geography comments: dating was based on "a combination" of magnetostratigraphy, ESR, and biochronology, but primarily the ESR date of 1.92 +- 0.18 Ma for a sample "less than 1 m below" the fossils
Environment
Lithology: siltstone
Taphonomic context: overbank deposit,paleosol,carnivore accumulation,human accumulation
Archaeology: stone tools
Habitat comments: the fossils are from "primarily silty sediments" 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, "butchery" is inferred, and carnivore activity was considerable at this stratigraphic level
there are 234 stone tools
