Any ideal what if anything this is

It's difficult to say what it is from a photograph without knowing how hard or heavy it is but the edge has a porous structure that resembles trabecular bone. If so, it's just a broken piece, not an arrowhead or artefact.

I am not sure if it is bone or not but I would say it is not an artifact. Projectiles have been made from bone especially examples from Cahokia. http://www.lithiccastinglab.com/gall...ointspage2.htm
