Is this indian pottery

[easle001]

Very new to the native american artifact thing so excuse my ignorance please. I have some property near birmingham alabama that is adjacent to the cahaba river and I notice a weird mound mound that I thought might be an old Indian trash pit or something. I dug around in it a little and the dirt was very rich and easy to dig. I found this thing and was wondering if it was a pottery shard. The ridges on it look almost to straight to be hand made. I am hoping somebody might have a clue what this could be. Thanks!!

almost looks like a clay pigeon maybe you should watch about digging around mounds

Looks like clay pigeon to me too. I find plenty shards of it in my artifact field, my son & friends would shoot em in that area, many still have the orange color, many are just like what you have in the pic.

Fairly sure that is some clay pigeon particles.
