Ok so I was hunting in Kansas and I came across this.. I almost left it laying there thinking it was just a hunk of chert. Buuuut I looked closer and there are flakes on all sides of this thing.. almost looks like it was used as a hammer or something.
I have no idea! But that "other side view" shot looks sort of like the image of a face at an angle, like the one that was photographed on mars. Not trying to be funny. We don't have any rock like that in my area that I'm' aware of, sure looks interesting though, hope you find out!
looks like a core. they would break off bigger pieces to make points . either there wasn't enough there to break off anymore or they were saving it for later. or they did use it as a scraper.
