Reference: R. Potts, P. Shipman, and E. Ingall. 1988. Taphonomy, paleoecology, and hominids of Lainyamok, Kenya. Journal of Human Evolution 17(6):597-614 [ER 3865]

Lithology: siltstone

Taphonomic context: carnivore accumulation,lake deposit

Archaeology: stone tools

Habitat comments: "none of the criteria for butchery sites is met. Instead, the primary fossiliferous layer (Khaki 2) represents a debris flow which introduced artifacts and possibly some bones into a lake margin setting... hyenas accumulated most of these bones in burrows after deposition of Khaki 2... evidence of hominid activities is negligible"
most of the fossils are from the Khaki 2 layer, a "poorly sorted, massive silt, 1-2.5 m thick" with "abundant rounded fragments and cobbles of Magadi Trachyte" that is "interpreted as as subaerially deposited mudflow"
