AMAZING DISCOVERY OF PREHISTORIC ROCK ART IN AUSTRALIA

Sometimes a stroke of luck or an accidental event can lead to the most amazing discoveries. Giles Hamm of La Trobe University, Australia, had been surveying gorges in the Flinders Ranges in Southern Australia, in the company of local tribal elder, Clifford Coulthard. Clifford suddenly had to answer a call of nature and wandered out of sight, into a side gorge, which formed a type of rock shelter. It was there that he saw some amazing rock art.

On closer investigation they discovered evidence of well-crafted stone tools and the bones from a long extinct marsupial, with the name Diprotodon Optatum. When the artifacts were radio carbon dated they were astounded to discover that they dated from approximately 47,000 BCE, not long after it is believed that humans first arrived in Australia. In fact, this find pre-dates any similar find by approximately 10,000 years.

Hamm published his findings in the journey Nature and is intrigued by what he found: "The old idea is that people might have come from the East, from the Levant, out of Africa, and these modern humans may have come with a package of innovative technologies". He went on to say "But the development of these fine stone tools, the bone technology, we think that happened as a local innovation, due to a local culture evolution".

Not everyone, however, is convinced. The dating comes from analysis of burnt eggshells and the layer in which they were discovered. Huw Barton, bio archaeologist from the University of Leicester (UK) believes the fragments may have dropped lower and represents human occupation 10,000 years later, in line with other finds in the area. Further study is obviously needed.
