Native American grindstones of some kind?

[Detector mom]

Found in northern NJ, known Indian hunting/encampment site going way back. (I've found Darling-Hardaway points here and in another area of the same mountain range.)

One side of the triangular stone appears to be charred...not sure. The smaller one is less hollowed out than the triangular one.

Any insights, appreciated...

They don't appear very compelling to my eye, but this kind of stuff is out of my league.

Looks to be just a rock but if you found three of them in one spot Id be worried Odin might come looking for them

Natural rocks. Not indian artifacts.

Always good to ask

I say nutting stone. Lithic artifacts aren’t always magnificent works.
