I found this last Sunday along with the Quartz celt. It looks to be a well used hammer stone or grinding stone. Looks to be used on both sides of it, top and bottom. It has a neat shape too.
It does show use great find JMO I would say a hammer stone for spalling larger stone into smaller knapping size and I say this because the use marks are on striking edges. We don't really know for sure it's all a guess on some items.
