Note number in brackets in title is just my inventory number.

I dont recognize much here and mostly the artifacts look like offcuts after they were chipped into tools but there are probably a few scrapers. Certainty a cheap enough  study lot of obviously worked flint from ancient man. This to me looks like the nomad finders found an old quarry that was basically a workshop for making tools. Just my guess. You might recognize some items.

 These stone artifacts were found in the Western Sahara Desert. Various types of stone tools, chipping stones, pounding and cutting stones and whatever man needed tens or hundreds of thousands of years ago. Many might be broken or not identifiable. Look over photo closely as what you see is what you get. Technology from our very distant ancestors. Found in the Sahara Desert by nomads searching for meteorites.

Dating stone tools is highly problematic as technology changed very little for upwards of a million years. But they generally got smaller and more detailed as time went on and by Neolithic times they started to get smoothed out. Some could be over a million years old but most are probably more like 50,000 or 100,000 years old. Most would be pre Neolithic.
 

The Western Sahara was occupied for more than a million years by various types of humans and our ancestors. The most common species of man during the time period when these tools were made would have been Homo Erectus man. From Wikipedia (Reproduced as per their commons licence) - Homo erectus (meaning 'upright man') was a species of archaic human from the Pleistocene, earliest occurrence about 2 mya and are among the first recognisable members of the genus Homo. Homo erectus was the first human ancestor to spread throughout the Old World, having a distribution in Eurasia extending from the Iberian peninsula to Java. African populations of Homo erectus are likely to be the direct ancestors to several human species, such as H. heidelbergensis, H. antecessor, Neanderthals, Denisovans, and ultimately modern humans.
