Coordinate: 23° 50' S, 130° 51' E
Coordinate basis: stated in text

Time interval: Holocene

Max Ma: 0.0083

Min Ma: 0.0007

Age basis: radiocarbon (uncalibrated)

Geography comments: "Puritjarra is situated in the Cleland Hills, 60 km west of the MacDonnell Ranges on the northern rim of the Amadeus basin" in central Australia.
Deposition of the fossiliferous Layer 1 began 8.3 ka with the earliest remains dating to less than 0.7 ka (dates for the underlying Layer II are uncalibrated, so these are also presumed to be such)

Environment
Lithology: sandstone

Taphonomic context: human accumulation,rock shelter

Archaeology: hearths,stone tools,other structures

Habitat comments: "Layer 1 is a consolidated layer of sand and rock spall ... grading into aeolian sediments outside the rock shelter".
"The matrix of Layer 1 is made up of light-brown sand, sandstone rubble and numerous fine rock fragments".
"The layer contains lenses of rockfall, intact hearths and pits, well-distributed pieces of charcoal and finely fragmented bone". Numerous flaked stone artefacts are also present.

Methods
Life forms: rodents,other large mammals,other small mammals

Sampling methods: quarry,screenwash

Sample size: 95 specimens

Sampling comments: "All sediments were weighed and screened through 3 mm and 6 mm sieves".
Note: In addition to the mammal counts below, remains of several unidentified species of reptiles were also found in Layer 1, including 1 snake and 12 lizards belonging to the Agamidae, Varanidae, and Scincidae families.
