Long-distance weaponry identified at the 31,000-year-old archaeological site of Maisières-Canal      (via sciencedaily.com)     Original source 

The hunter-gatherers who settled on the banks of the Haine, a river in southern Belgium, 31,000 years ago were already using spearthrowers to hunt their game. The material found at the archaeological site of Maisières-Canal permits establishing the use of this hunting technique 10,000 years earlier than the oldest currently known preserved spearthrowers. This discovery is prompting archaeologists to reconsider the age of this important technological innovation.
