Identification Request

[BLT]

I found this rock in a middle Tennessee creek this morning. (Mississippian, St. Louis Limestone & Warsaw Limestone) I would like to know if it is some type of fossil? If not, which type of rock/mineral is it? I’ve seen somewhat similar rocks around here, but nothing quite like this one.

I would go with fossil on this one, but have no idea what type.

Not really that hard to do, I am not as well versed with taxonomy as others here.

might be an auloporid coral.They CAN look like that,depending on how they are sectioned

I just noticed Syringopora is known from the Warsaw

Don't think I've ever seen a rock that came with a grid pattern before.

I do wonder what caused it to fracture like that.

I think probably Syringopora too though I can't see quite enough detail to be sure. Tabulate coral anyway.

The first pic looks sort of like 2 rocks glued together.. with the seam not quite blended in all the way.. (maybe it's Moroccan)

I don't think it's moroccan and glued, i think it has been fractured.

I am in the coral camp.

Honestly? I never once thought it actually was from Morocco, I just have a warped sense of humor. I know it's a fracture & it goes along with the weird grid pattern fracture on the backside.
