Archaeologists in Saudi Arabia have discovered a massive cache of stone artifacts, some of them more than 1.7 million years old. The researchers are part of the DISPERSE project, which studies the diaspora of early humans across Africa and Asia. The artifacts, more than 1,000 of them, were found in a basin of porous rock bordered by volcanic lava flows, just a few miles from the coastline of the Red Sea, according to an update from the DISPERSE project's website. Live Science reported that one hand axe weighs nearly eight pounds, making it notably heavier than the rest. It's the first of its kind discovered in the Arabian Peninsula, according to DISPERSE. read more Disclaimer: Chances are that this post was requested by an advertiser.
