Is this a point? I really need your help! :)

[autographcollector11]

Attached are images of what I believe is a broken point. Found in NE Illinois. I have my ideas as to what type and era, but I would like your opinions. The stem is broken but I added an outline of my best guess as to how it looked.
The edges are serrated, somewhat thin and flaking patters are average.


Any help would be appreciated.


Thanks!

Definitely a point possibly a small spear. Keep looking in that area should be more. Good luck and happy hunting!

Looks like an Adena Dixon type to me it also looks heat-treated I think those are late archaic to woodland
