I’ve responded to this same subject a couple of time now, once on this forum. What we’re looking at is what many of us collectors and knappers call a Hell Gap, not pre Clovis! It’s just one of the many style points they produced during the Paleo Period. Knappers of that period produced a wide variety of points with much of it determined by the quality of the material they were working. To think that an experience knapper would only make one style point is rather amusing since we see many times where tools were knapped for specific needs
Sorry, I know next to nothing of the subject.
