This Acheulean prehistoric stone tool is a UNIFACIAL SCRAPER. It was made and used by Homo ergaster (African Homo erectus) over a half a million years ago! It was surface-collected from an exposed Acheulean site in the Northern Sahara Desert of North Africa. This Lower Paleolithic tool represents the first intelligent design type known to science that was made by primitive humans. Prior to these Saharan Acheulian tools, only crude pebble tools existed in the human fossil record.
This Lower Paleolithic stone flake scraper tool was used when there were large elephant, hippopotamus and giraffe species in Africa that primitive humans would have hunted. A tool like this was necessary to butcher such large kills. This flake scraper is a UNIFACIAL DISCOIDAL scraper. It's broad, round form and sharpened cutting edge encircling the tool, would have made it ideal to deflesh large animal hides from hunted game. Edge photos show extreme wind erosion over original prehistoric secondary flaking once done to sharpen the edges. The proximal end shows a flat struck base that served as a grip. This tool exhibits excellent workmanship is complete as originally made. African Stone Age flake tools from the Acheulean period are much more scarce on the market than hand axes. It most likely is a factor of it being difficult to differentiate a flake scraper from all the natural stones on the surface of the North Sahara, compared to a hand axe that has a more "manufactured by humans" appearance.
During this time in prehistory when this Lower Paleolithic tool was made, the Sahara Desert (where this stone tool was found) was a savanna rich in wildlife. Prior to the prehistoric global warming that turned the vast region to desert, early humans lived alongside prehistoric giraffe, bison and elephant, which were vital to their survival. Hunting and butchering these animals would have required specialized tools such as this Acheulean specimen.
