Found at a washout. Is this pottery?

Found these pieces at an eroding shoreline along a river near an ag field in Delaware. It’s porous and sure feels like clay, orangish in color. Some definitely have curvature, especially the smaller pieces as you can see below. It also seems layered and a bit platey in structure. Most are orange and smooth on one side, but dark and gritty on the other. Thoughts?

Here’s one last piece I found for reference

Looks like limonite a type of bog iron deposit.

Surface layer of sedimentary strata. Not pottery. You can usually tell pottery by it's shape, content and the presence or absence of temper.
