Side notch-woulda been nice

[Hunter1499]

Found in Illinois . Looks like a side notch. Not a lot left but any idea on type or age? It’s the size of a quarter. Need to rotate 90 degrees to the right btw.
Thanks

A fragment of an arrowhead. Not much left to go by. White flint, found in IL, probably Burlington. Gary
