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: carnivore accumulation,human accumulation,paleosol

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

Methods
Life forms: carnivores,ungulates

Sampling methods: quarry

Sample size: 103 specimens

Sampling comments: there were "limited trench excavations"
