Australian scientists has unveiled the biggest-ever graveyard of diprotodons, with the site potentially holding valuable clues on the species' extinction. The remote fossil deposit in the Queensland outback is thought to contain up to 50 diprotodon skeletons including a huge specimen named Kenny, whose jawbone alone is 70cm long. Photo courtesy: AFP
