another mystery point, i love it. a couple guesses, first guess would be yarbrough,2nd would be lange. if the stem is ground i would stick with my first guess. very unique point. so did u nique up on it.
This is just a shot in the dark but I would like to suggest perd, pre fluting. I know when they fluted some paleo points, they used a "platform" similar to what you see at the base of the point. Although I have never seen the remnants of this platform, on perds while they are still evident on paleo points. Just some food for thought.
