Age basis: OSL

Geography comments: "within the Victoria Fossil Cave, approximately 50m from the main Fossil Chamber... The age of the Grant Hall fossil deposit has been constrained between 206 ka and 76 ka by uranium-series dating of associated speleothems"
OSL dates on sediments associated with the faunal assemblage range from 93 ± 8 ka to 76 ± 6 ka (Macken et al. 2011).
coordinate based on Naracoorte Caves National Park

Environment
Lithology: sandstone

Taphonomic context: cave,pitfall trap

Habitat comments: "The fossil-bearing sediments were sandwiched between separate flowstones that covered the limestone base of the cave and overlaid the sediment's surface... The sediments were largely homogeneous, consisting of a mixture of red/brown and pale yellow medium to fine sub-rounded quartz grains, mixed with darker red-brown clay particles... The natural trapping of unwary animals via a pit-fall was therefore proposed as the predominant method by which the large mammal bones came to be in the cave"
