In addition to the megafauna, the researchers have also uncovered a wealth of smaller animal fossils, plants and insects, which give more indications about what the ecosystem of the time was like. The giant kangaroo tibia (shinbone) found at the megafauna fossil sites of South Walker Creek, travelled safely back to the Queensland Museum’s Geosciences collection. "One of the key sites we have is aged at 40,000 years ago, which is actually younger than the expected extinction event around 45,000 years ago. To find out if the same was true of balbarids, Dr Kear and his colleagues analysed the few bones they had unearthed belonging to one known as Nambaroo gillespieae, comparing them to different modern relatives that live in trees and on the plains. One of the most exciting finds at the site for the researchers has been the discovery of an entirely new species of giant kangaroo, the largest ever found. Scientists have debated for years whether humans, a changing climate, or a combination of both caused the eventual extinction of practically all of the continent’s megafauna. But the newly discovered species has not been found anywhere else in the country, meaning it probably filled an environmental niche similar to what Procoptodon inhabited in southern parts of Australia.

Dr Hocknull said combined with mammalian predators like the marsupial lion Thylacoleo carnifex, also found in the area, it would have been much more likely that those early humans would have tried to avoid megafauna entirely.
