Where: Victoria, Australia (37.3° S, 144.7° E: paleocoordinates 37.3° S, 144.7° E)
• coordinate stated in text
• outcrop-level geographic resolution
When: Late/Upper Pleistocene (0.1 - 0.0 Ma)
• "3.5 m of an alluvial clay overlying Pliocene basalts" including a "~ 0.2-m-thick bone bed"; radiocarbon dates from the bone bed range from 8775 +/- 260 ybp (which is regarded as a low minimum) to 19,800 +/- 450 ybp (the only date regarded as accurate), but the "roughly contemporary" underlying channel fill is dated at 25,200 +/- 800 and 26,600 +/- 650 ybp
• bed-level stratigraphic resolution
Environment/lithology: mire or swamp; paleosol/pedogenic, shelly/skeletal, black, green, conglomeratic claystone
Size class: macrofossils
• "Some of the bones... show the toothmarks" of Thylacoleo and "a large quartzite blade... was found firmly embedded in the bone bed"
Preservation: original phosphate
Collected in 1974, 1975, 1977
Collection methods: bulk, quarrying, sieve,
• "The 1975 excavation of 5 m2 yielded some 3000 bones, representing a minimum number of individuals of 72 for all species" with 90% being Macropus titan, 7% being Protemnodon, and all other species accounting for < 1%; excavated sediment was apparently screened
