Sample pages hot off the digital press!

My wizard book designer Robyn has already begun work on the layout, illustration and design for Ancient Australia Unearthed. You wonderful people get the exclusive first peak at some sample pages. We’ve got What is History?Homo floresiensis (aka ‘The Hobbit’) and The Mount Toba eruption. (These double-page spreads are all unedited drafts, so if you spot any errors, please let me know!)

As of this afternoon, the Pozible total has nudged $3,402. Thanks to everyone for the ongoing support in bringing Ancient Australia Unearthed to life. There’s only 29 days to go, so the journey isn’t over yet. Keep spreading the word!

The Jinmium Controversy

JinmiumIn 1996, a team of archaeologists excavated Jinmium rock shelter, which is located in a remote area of the Kimberleys. They found a rich array of stone artefacts, as well as some stone engravings called ‘cupules’ that are thought to be examples of some of the oldest form of rock art in the world.

In their preliminary findings, the archaeologists published the following:

We report stone artefacts found in sediments dated by thermoluminescence (TL) to greater than 116,000 ± 12,000 years. If that correctly dates the human presence in Australia, it almost doubles previous luminescence age estimates and is beyond any possible overlap with radiocarbon determinations (Fullagar et al, 1996).

The archaeology team concluded that this finding signalled a need for further investigation into the occupation dates at Jinmium.

As soon as these preliminary findings were published, the media pounced, reporting that Australia had been occupied for up to 176,000 years. Here are some extracts from journal publications and news reports:

Jinmium response

Jinmium’s sediments were recalculated for verification, and it turned out that the thermoluminescence dates were correct – but the artefacts found in the lower layers were much younger than their surrounding stratigraphy.

It turned out that the sediments at Jinmium had shifted, meaning that lower layers were contaminated with material from the upper layers. The TL dates were correct, but archaeologists concluded that sand grains weren’t the only things moving up and down in the ground. The artefacts had moved as well.

The artefacts excavated from the deepest, most ancient layers at Jinmium had in fact been pushed down from the upper levels, possibly as a result of the soft, crumbly bedrock, which meant that artefacts could easily have fallen through the gaps in the stone. It could also be because many people over thousands of years had been trampling on the dirt and this pressure had pushed the artefacts deeper into the ground.

After extensive analyses of sediments and repeated dating methods (about six dating methods were used at Jinmium), it was determined that Jinmium’s artefacts were only around 10,000-20,000 years old. The media’s misrepresentation of the science had turned a tentative hypothesis into an explosive news headline.
