>>>QUOTE:I have experience with quarts, when the tool is new is difficult to know what is it, (some are complex) but when they are used a lot you find the surface in contact with the hand very soft, you just try to wrap it with all fingers and palm, you wont miss, the coarse parts still rough, the part in contact with the hand soft, that's why I talk about hand fit, then they reveal what are they used for. Not all material are flint. Oldowans A And B used Quartz and Basalt in Africa hundreds of thousands years back in time. then they worked with obsidian, the ancestors worked with materials available in their areas, the know how to craft them was in their heads. <<<

Sadly, I think you have very little experience with quartz (not least in that you are unable to spell it properly) and the misinformation you have been posting only serves to demonstrate that. To be completely frank, although we have no restrictions on the forum against people posting their opinions in the polite manner that you have exhibited, it helps no-one (including yourself) to allow these kinds of opinions to go unchallenged.

If you truly want to learn about lithic materials, the artefact types made from them, and the techniques used throughout time by different cultures, then you've come to the right place. I think you'll find that our minds are perhaps more open than yours. You have a lot to learn, and delving into highly specialised papers about the Oldowan progression to the Acheulean Industry in Africa is not the best place for a novice to start, nor a good reference point for North American artefact types.. You have a rather odd perspective on the way in which 'Old World' lithic technologies spread into the Americas since they came via an indirect route from Africa into Eurasia and by that time were Upper Palaeolithic in nature, not Lower Palaeolithic. It's not the case that the arriving people regressed a million years and started again from scratch with Oldowan, Acheulean or Lower Palaeolithic techniques as the start point. Yes, of course some techniques have persisted throughout time, but it's the refinements in those techniques and other advancements that allow us to characterise specific lithic industries.

I hope that you take this in the spirit with which it is intended.

Yes, thanks, challenge is good, It's a forum that's the way it should be. you are wright, no much experience, I do have some quartz objects, they are ground stone tools, difficult technique and very laborious. Yes the article is heavy, but there the authors note that basalt and quartz where used a lot too.

Got a Exacto Knife, put my fingers where it showed wear and fit perfectly!

It just doesn't seem to be registering, those are not tools nor artifacts. They are just rocks, they were not made or manipulated by man. That IS NOT an ancient "exacto" knife. Just because something fits your hand well DOESN'T MEAN it's an artifact, it just means you can hold onto it, nothing else. And in no way can you compare African artifacts to the ones found here, it doesn't work that way... Please take some time to familiarise yourself with the actual types of artifacts found in your area, you will be happy you did and will thank us for talking you out of your misguided notions. You can do that by browsing our forum were plenty of actual artifacts are displayed for your viewing pleasure.
