Possible nutting stone or hammer stone

[IowaDigger]

I found this on the banks of the Mississippi in Iowa, near a broken axe. It looked too round, too even so I picked it up. That’s when I saw the concave depression in the center of the perfectly flat bottom. I’m wondering if this is a nutting or hammer stone

I actually found 2 now with a possible preform or Celt within 20 ft of this!

Nice hammer looks perfect. Most of the ones I found are beat up on one side from pounding. Hard Stone is always a good find

Nice finds id love to find some hardstone. If the axes and celts were close by I could get behind the first being a nutting stone

Everything so far is from within about a 25 yd circle. Also found there is a point and point tip. I also have a possible hammer stone found close last year
