Arrow86, have only been to this certain spot once and have not found any points or such. its in the Great Dismal Swamp area of virginia, rite off an old road. Pretty good potential for Native activity.
Like a few have said, looks like a game stone. I’ve found clay marbles at native sites, game stones, beads, and about anything Native Americans used. It’s not uncommon to find an item like that in a creek, but if it was in a field it would be much different. There’s a lot of speculation to what items like the clay marbles, game stones, and other pieces that aren’t easily identifiable such as a arrowhead would be. Most academics will say it’s just a rock, weathered in a circle pattern. It may be a game stone, small grinding stone, round ball for breaking acorns up, or just about anything.
Unlike us Native Americans didn’t have cell phones, laptops, or any luxuries, so they passed their time making items for use in harvesting animals, processing hard items like acorns, grain, or even break oyster shells into small pieces for mixing in their clay for pottery. It’s a guess, as I’ve found similar stones in bluff shelters with a plethora of Native American artifacts on my uncles property, so it’s one of them things, where you’ll get some saying “just a natural stone”, and others who have found them in context with other Native artifacts will say it’s a Native American artifact.
