dingo remains in the Torres Straits date to 2,100 YBP. In New Guinea, no ancient New Guinea singing dog remains have been found. The earliest dingo skeletal remains in Australia are estimated at 3,450 YBP from the Mandura Caves on the Nullarbor Plain, in southeastern Western Australia; 3,320 YBP from Woombah Midden near Woombah, New South Wales; and 3,170 YBP from Fromme's Landing on the Murray River near Mannum, South Australia. Dingo bone fragments were found in a rock shelter located at Mount Burr, South Australia in a layer that was originally dated 7,000-8,500 YBP. Excavations later indicated that the levels had been disturbed, and the dingo remains "probably moved to an earlier level." The dating of these early Australian dingo fossils led to the widely-held belief that dingoes first arrived in Australia 4,000 YBP and then took 500 years to disperse around the continent. However, the timing of these skeletal remains were based on the dating of the sediments in which they were discovered, and not the specimens themselves. In 2018, the oldest skeletal bones from the Madura Caves were directly carbon dated between 3,348–3,081 YBP, providing firm evidence of the earliest dingo and that dingoes arrived later than had previously been proposed. The next most reliable timing is based on desiccated flesh dated 2,200 YBP from Thylacine Hole, 110 km west of Eucla on the Nullarbor Plain, in southeastern Western Australia. When dingoes first arrived, they would have been taken up by Indigenous Australians, who then provided a network for their swift transfer around the continent. Based on the recorded distribution time for dogs across Tasmania and cats across Australia once Indigenous Australians had acquired them, the dispersal of dingoes from their point of landing until they occupied continental Australia is proposed to have taken only 70 years. The red fox is estimated to have dispersed across the continent in only 60–80 years. Based on a comparison with these early fossils, dingo morphology has not changed over thousands of years. This suggests that there has been no artificial selection over this period and that the dingo represents an early form of dog. They have lived, bred, and undergone natural selection in the wild, isolated from other canines until the arrival of European settlers, resulting in a unique canid.
