Pottery Shard?

[relicdigger3]

Hey guys, I found this small piece of what I think is Native American pottery but I’m not sure. I found this in south Florida in an area where there is a lot of shell debris which I believe could’ve been a midden site. What do you guys think?

I don’t know Florida pottery but I’m not aware of any native glazes if that’s what that is, I wonder if it’s some remnant of a fossil shell or something that one layer stuck while the rest fell out

No pictures of the edges, does not look like native pottery, most ancient Florida natives used crushed shells, sand or fiber to temper the clay to make it stronger, it would be visible in the cracked edges, there also there would be no glaze.
