Geography
Country: Indonesia
State: West Sumatra
Coordinate: -0.64475° S, 100.647049° E
Latlng basis: stated in text
Time interval: Middle Pleistocene
Max Ma: 0.16
Min Ma: 0.115
Age basis: ESR
Geography comments: "approximately 90 km east of Sawah Lunto City"
there are five ESR dates, but sample "SUM18-21a most likely provides the most reliable chronological constraint" which based on a detailed discussion "lies somewhere between ~160 ka and ~115 ka" and is therefore Middle Pleistocene

Environment
Lithology: claystone
Taphonomic context: carnivore accumulation, cave, rodent accumulation
Habitat comments: the cave was formed in "Carboniferous-Permian limestones"
"well-preserved Pleistocene fossiliferous breccia and sediments" and specifically "an unconsolidated clay-rich mud matrix"
"There are no cut marks or intentional bone breakage, marks or modification, so we cannot relate the bone assemblage to human activities or bone collecting behaviours"
"numerous small carnivores" and Hystrix are "definitive" accumulation agents

Methods
Life forms: bats, carnivores, primates, rodents, ungulates, birds, lizards
Sampling methods: quarry, screenwash, surface
Sample size: 293 specimens
Net or trap nights: 0
Basal area status: not applicable
Sampling comments: fossils were "removed from this breccia by hand and pick" and "sediment was sieved through a 5 mm mesh "
