Geography comments: "Kudjal Yolgah Cave (KYC) is situated in the Leeuwin–Naturaliste National Park, 5 km southwest of Forest Grove", in southwest Western Australia.
"It lies within a Pleistocene-age limestone ridge that stretches from Cape Naturaliste in the north to Cape Leeuwin in the south".
Unit 1 dates to about 1.2 ± 0.1 ka, based on one single-grain OSL age.

Environment
Lithology: sandstone
Taphonomic context: pitfall trap
Habitat comments: "Seven units were recognized during the 2008 excavations, based on sedimentary colour, texture, compactness and unconformities; Unit 1 is stratigraphically the highest and Unit 7 the lowest. All units are composed of highly friable, medium to very coarse sands with predominantly rounded grains".
Fauna and sediments were deposited via an overhead solution pipe. By 1.2 ka, the original solution pipe had blocked completely and sediment began to enter the cave via the current solution pipe entrance. Unit 1 is still accumulating via the current entrance.

Methods
Life forms: other large mammals,other small mammals
Sampling methods: quarry,screenwash
Sample size: 49 specimens
Years: 2008
Sampling comments: "Systematic excavations at KYC were conducted by a team from Flinders University in January, September and October 2008. The excavation area was divided into North and South Pits. Each pit was partitioned into around 1 m2 quadrants".
"Excavated sediment was removed from the cave for sieving with a 1.5-mm sieve to recover small bones, teeth and snail shells". Wet sieving was only carried out on sediments excavated during the January 2008 field season as a means of obtaining higher yields of small animal remains; this was discontinued after it was established that very few small animal remains were preserved in the sediments".
"All fossils excavated were registered with the Department of Earth and Planetary Sciences, Western Australia Museum", where the specimen counts below were obtained by the sample enterer during a visit in July 2022.
