This authentic prehistoric bifacial hand axe was made and used by early humans of the primitive species Homo erectus (ergaster). It was surface-collected from an exposed Lower Paleolithic Acheulean site in the Sahara Desert of North Africa. This Lower Paleolithic tool represents the first scientifically documented intelligent design made by primitive humans. Prior to these Saharan Acheulian handaxes, only crude pebble and flake tools existed in the human fossil record.
This is an exceptional fine grade BIFACIAL hand axe made out of FINE VESICULAR BASALT, stained reddish brown over time by the red Sahara sands. If you look closely, you can see the tiny holes in the stone that this type of basalt is famous for. It has Late Acheulean flaking of a refined nature with a flaked depression for the thumb when held in the right hand. Both sides show expert flaking to create a reduced size, and sharp chopping edge. The sharp tip is original and as it was originally made, hundreds of thousands of years ago. The surface shows a "desert varnish", a natural glossy surface caused by the exposure of the stone to the blowing sands over hundreds of thousands of years. Original sediment and some mineral encrustations are still present in microscopic crevices and cracks - a trait ONLY found in authentic Paleolithic artifacts like these. Tip and edges are intact with remarkable detail in the flaking on the edges.
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.
