Sure looks like a shallow stone bowl. Need to clean out depression and see if it has been smoothed at all,then you can tell more. Is that a fossil on bottom or just an imprint of a weed?Be on the lookout for points.

I'll take a closer look.

Is that a fossil on bottom or just an imprint of a weed?

There are at least three fossils on the bottom.

Be on the lookout for points.

Yes arrow heads or other artifacts. Are there flakes of stone in area?

That rock is limestone. There is a good chance it is natural and a softer rock or fossil encased in the limestone eroded away and left the hole. Gary
