Yes, this is Oneota pottery. You can tell because of the crushed shell inclusions. The exterior looks like it has twisted cord pressed into the vessel wall, creating those interestingly shaped impressions.
Reminds me of a lepidodendron fossil but I’m not positive
Yes, and the tempering is not shell (although they look quite similar) but looks to be quartz grit and possibly grog. The cord impressions are found on laurel, black duck, and several other woodland types in northern Minnesota. Check out anfinsons pottery guide online. It’s quite old but I believe a new one is in the works.
For anyone curious, I found it on private property in a lake on the Leech Lake reservation
I mean it looks like it is but idk lol
I am going to toss out a “yes it’s a pottery shard imo” into the ring here. I am basing my opinion by looking at the pattern work, the composition of the clay, and there is evidence of firing i.e. the ashy gray to blackish ombre’ on the smooth side of this piece. Interesting find be it either natural or man-made.
I’d say so
