Posted this earlier but now I'm questioning myself since it is small. Do you all think this should be called a nutter and let's see some of yours. Thanks
Seems like it was round for a purpose or from a repeated action anyway. I have a couple neather are round. One has two indents. The other one. that were ground into the stone both have impressions on the other side that show percussion damage.
I have one I found in my home here some place. Its made from a quartz rock and all the cortex is left on it. I believe mine is a hammer stone cause quartz is such a hard stone type. Yours looks like a softer stone type and wouldnt make a good hammer. JMO
It would definitely show chips if it were ever repeatedly smacked into another stone. Seems like it would have taken sometime and trouble to make it round. my guess is it was for a good reason.
