Did Clovis people have the atlatl?
Yes they did! Of course, clovis points of this size were probably not used as a spear point. The dynamics of such a heavy piece would prohibit distance and accuracy! More likely, it would have been used as a knife or it was strictly ceremonial. To bad these points can’t speak!
What I do know, is that they didn't have the bow; which was much more recent tech. Circle_Hook seems to have it covered in # 28.
