Geography comments: "Kelly Hill Cave (K1) is a non-cultural cave site on Kangaroo Island consisting of large cavities up to 25 m below the crest of Kelly Hill".
Layer 7C of K1–P2 is constrained by a radiocarbon date for Layer 7A of 8070 ± 40 BP, ranging from 9050–8700 cal. BP., and a radiocarbon date for Layer 7D of 12,220 ± 50 BP, ranging from 14,250–13,800 cal. BP.

Environment
Lithology: limestone
Taphonomic context: bird accumulation,cave,pitfall trap
Habitat comments: "The Kelly Hill Cave system consists of a series of cave entrances connected by extensive passages covering at least 36 000 square metres".
The system likely formed through water slowly infiltrating poorly consolidated dune sediments resulting in the dissolution of large lateral cavities that have matured into structurally stable chambers (McDowell et al. 2013).
The faunal remains likely accumulated "through a combination of pitfall entrapment of large hopping species and owl accumulation".

Methods
Life forms: rodents,other large mammals,other small mammals
Sampling methods: quarry,screenwash
Sample size: 78 specimens
Sampling comments: "A well-stratified late Pleistocene–Holocene accumulation containing abundant faunal material was excavated near the entrance of K1".
"The excavation (K1–P2) consisted of two 1 m × 1 m squares excavated to bedrock in 5-cm spits within layers".
"Sediment was dry sieved through a 12-mm sieve to retrieve large bones then washed through a 1.5-mm sieve to retrieve smaller faunal elements".
