I would say yes .. looks like a nutting stone. Nice save.

Added: Take a look at some of the ones here: nutting stone

A nutting stone is a possibility, but on a stone that small, I'd say natural.

Quarter for scale

More likely a Omarolluk or Omar for short.

Mire likely a Omarolluk or Omar for short.

Agree. They're very common in Michigan.



Of course a Native American could potentially make use of something naturally formed in a convenient shape, but nutting stones usually show some signs of use-wear/impact damage and I don't see it in the one you found. Just some weathering and erosion.
