Is this a hammer stone?

[Dirttrax]

I’ve found 3 of these now and was suggested it’s a hammer stone or maybe grinding stone. Maybe it’s nothing but thought I’d ask thanks

Well it does have a couple features consistent with a hammer stone.

I'd say yes but hard to tell without better close up shots of the edges. Hope you kept it!

The one in your hand sure looks to be one. Not sure on the others without more pictures.

They were found with about 20 broken points, 2 drills and more flint flakes than I’ve ever seen in one spot. Appears to be a camp.
