As far as I know (which isn't really much about Clovis), their projectile points are really all we have left to identify them. Did your friend have any insight into why they might have changed that aspect of their culture?
Interesting question. No, we didn’t discuss Clovis points.

I visited a museum in the mid south a few years ago. They had a lot of points that were around 8,000 years old. i think they were all a lot smaller than Clovis points because all the large animals except Bison were dead. Chasing Bison over cliffs was one way of killing them.
