"Why do you ask? Was there evidence to suggest the weapons had never been used and were later dropped while running?......:)"

LOL! No, I'm not casting aspersions upon the ancient Peruvuans! It's just that a lot of old stone tools were found in prehistoric sites in France and there appears to be come commonality of design with their New World counterparts.

Funny you would mention that.
I have a greenstone full groove "hammer" or "ax" that was found up on the ridge near my house. [Appalachian mountains of western MD]
The tool type is usually ascribed as having been made by the enigmatic "archaic/woodland Indians".
The resemble more than anything else, ancient stone tools commonly found in Europe.
I'm sure you've heard of the "Pangaea" theory.
What if the tools were here *before* the continents drifted apart and have nothing at all to do with "Indians"?
