The Lancefield Swamp is a rich fossil deposit from the epoch was discovered in the 19th century near Lancefield, Victoria, Australia.
The site consists of a bone bed lying directly atop a layer of fluvial gravel between layers of clay. The layer of bones is estimated to contain the remains of perhaps 10,000 individual Pleistocene animals. A total of at least 6 Megafauna species are represented, although the majority of bones are from Macropus giganteus or Macropus titan.
Human artifacts were found in the bone bed and in the overlying clay. However, evidence of reworking by water flow has been noted. Thus it appears possible such artifacts are intrusions.
The Lancefield Swamp fossil site is important in the debate over the time of and causes of the extinction of Australian Megafauna. Humans are estimated to have arrived in Australia, or Sahul, at anything from 60 ka to about 45 ka.
Initial radiocarbon dates yielded estimates of 31ka, a comparatively young age approaching the Last Glacial Maximum. Horton therefore claimed Lancefield as a decisive example of the survival of Australian Megafauna for many thousands of years after the arrival of modern humans in prehistoric Sahul.
