Geography
Country: Morocco

State: Casablanca-Settat


Coordinate: 33.568817° N, -7.696655° W
Coordinate basis: estimated from map

Time interval: Middle Pleistocene

Unit number: 4

Unit order: above to below

Max Ma: 0.501

Min Ma: 0.36

Age basis: OSL

Geography comments: Initial dates of fossil hominids obtained through OSL indicate an age of 470-360 ka for Thomas Quarry GH Strat unit 4

Laser ablation ICP-MS has pushed back the date towards 500 ka

Environment
Lithology: siliciclastic (mixed)

Taphonomic context: carnivore accumulation,cave

Archaeology: stone tools

Habitat comments: "The main part of unit 4 is composed of bioclastic and quartzose sands and are associated to more or less abundant red clays that coat grains or make up small aggregates in packing voids"

Components of lithic assemblage include cores, debris of cores, flakes, small flakes, bifaces, debris, and hammerstones

"Cut marks are still absent from this assemblage despite the association with lithic artefacts, which raises the question of any human role in the bone accumulations"

Methods
Life forms: carnivores,primates,rodents,ungulates,marine mammals

Sampling methods: quarry

Sample size: 625 specimens

Sampling comments: Modern controlled excavations have been undertaken since 1988 in lower deposits

"Between 1994 and 2008, new hominid fossils were discovered associated with a lithic assemblage and a rich fauna and micro fauna"
