The Keilor archaeological site was among the first places to demonstrate the antiquity of Aboriginal occupation of Australia when a cranium, unearthed in 1940, was found to be nearly 15,000 years old. Subsequent investigations of Pleistocene alluvial terraces revealed hearths about 31,000 years BP, making Keilor one of the earliest sites of human habitation in Australia. Remains of megafauna suggest a possible association with Aboriginal hunting.
