VERY good read. The search / theorems for the "first Americans " is both fun and very elusive.
At this point in time, Put ANY two people in a workshop together and there will be at LEAST two different
opinions.
In that report notice that it states that bone projectile points were PRE CLOVIS because stone points
had not yet been invented..

Where on earth did these mammoth slayers come from that they could not knap stone ?
Most of the known world at that time had been using stone for over 30 thousand years.

That point in a RIB looks painful....Now they had 5 tons of irate animal to play with

The statement about hunters using bone points because they had not yet learned to use flint was just a "Reporter's Error" by Eric Berber who wrote the article for the Houston Chronicle. A flint tool was used to fashion that bone point.
