This arrowhead was found in the Saharan desert of Mauritania. This arrowhead dates from the Neolithic period. Approximate age of this arrowhead is 5000 - 10,000 years old. Many thousands of years ago, the Saharan desert was a green grassland that was teeming with life. Roaming these grasslands were ancestors of man, armed with various primitive weapons - flint axes and bow/arrow. These arrowheads were carved out of native available rock - typically chert, but sometimes agate or whatever was handy. Considering their age, these arrowheads are in excellent condition. At one time, these artifacts were more common, but the supply has dried up and relatively-few of these arrowheads are making it to the market now.
This arrowhead is part of a larger lot that I acquired from a reputable dealer of artifacts and meteorites, who in turn bought them at a European mineral show from a Saharan vendor. This particular specimen has barbs/notches in the sides.
Refer to the photo. The black centimeter cube is shown for scale and is not included.
I only have a limited supply of these artifacts.
