"New combined ESR with U-series dating of seven bovid and rhinocerotid teeth from both lower and upper sets give ages of 720–690 ka and 548–522 ka" with exact values for the two units of 720 +/- 64, 691 +/- 75, 548 +/- 56, and 522 +/- 56 ka

Environment
Lithology: sandstone
Taphonomic context: aeolian deposit, carnivore accumulation, cave, fluvial deposit, human accumulation, rodent accumulation
Archaeology: stone tools
Habitat comments: an original and current cave with "calcareous sandy materials divided into two main lithostratigraphic sets: the upper set (units 1 to 4) and the lower set (units 5 to 6)... The deposition of fine sediment by low energy processes (aeolian and runoff) is responsible for the good preservation" and this is not "a pitfall accumulation"
there is "a rich Acheulean lithic assemblage"
there are "carnivore tooth-marks (pits, scores, punctures, notches) and ingested remains... Porcupine tooth marks are also present in greater quantity in the lower set" plus some human-made "cut-marked specimens" and "percussion marks" in both stratigraphic units but "hominins were not the main agent of accumulation"
