Comparison of DNA from the bones of megafauna animals and the traces on the stone artefacts shows that they were used to butcher Macropus titan (a giant kangaroo) and Diprotodon.
So at least at this place the Aboriginal People were eating megafauna animals.
At Cuddie Springs, megafauna bones and artefacts occur in the same strata in association with charcoal that provides secure dates.
Artefacts are found associated with bones of megafauna, as well as in earlier and later levels.
It is usually accepted that the giant kangaroo, Macropus titan, went extinct.
There are those who believe that rather than becoming extinct, they simply down-sized, evolving into the Eastern Grey Kangaroo, Macropus giganteus, also known as the Great Grey Kangaroo, the largest of which get about 2/3 of the size of Macropus titan.
The emu, having such a wide range of food plants, simply adjusted its eating habits to whatever was available.
The fossils of some Diprotodons have been found with the remains of plant material about where their stomach would have been.
Elsewhere in the world large stone points were associated with megafauna hunting.According to Flood (2004), about 50 species of large animals, the megafauna, including marsupials, reptiles and birds, went extinct in Australia in the last 100,000 years, about 41 going extinct in the Late Pleistocene.Most of the macropods that went extinct were browsers, as was the Diprotodon.Amino acid racemisation was used to date the shell of the 2 birds.It was found by comparing the types of carbon in the shells, both were herbivores, that while the Genyornis was apparently a picky eater, the emu ate a much wider range of food.
