Pottery or tree bark or ?

Found the 2 pieces a few days ago and was wondering if they could possibly be pottery? Thanks coop

It look's like it is pottery shards to me.

I don't think it's tree bark but don't know if it's pottery either LOL

Not sure if it pottery or not, but those designs sure look intentional!

They do don't they. Must be pottery then, don't you think?

Looks like pottery to this uninformed artifact enthusiast.

Those are really interesting. They look to be slate or shale not sure though as i do not have them in hand. They look like some sort of tablet stones. If you look closely they have intricate designs on them. The one that has hafting grooves in it looks like it has human petryglyphs on it as well as deliberate lines. The other one as well. The other one doesn't have the human petryglyphs. I would venture a opinion on a Tablet stone telling some kind of story. Look at them closely. They have some sort of meaning to them. The one that has hafting grooves looks like it was a old axe or something........................JMO.............. .............GTP

From the pictures it looks like stick incised pottery. Pots got greasy and this put a texture on them. Looks fired from the photos. If it is heavy or shale it may be a fossil. Color looks to be from a more northern state Does each piece have a slight curve?
Matt knows his pottery maybe he will chime in.
