I was finding points in this area ..so ill just hold on to it for awile ..thanks..Fla-Gal said:All rock 'tools' started out as ROCKS and many useful 'tools' were left in place for the next useful purpose.....lots of debate in this arena, I know, but utility of a rock during ancient times may yet be fully understood. Watch the PBS/Monchu Picchu special about how the HUGE mountaintop boulders were chipped into a snug fit little by little.
So, keep looking w/an open mind....I still do...
