Looks like the fossilized/petrified mud from inside of a snail shell of some type.

Thanks newnan man. You sent me on the right track. I google fossil snail internals and found it's a Platyostoma Gastropod.

So would this be a trace fossil like an ichnofossils ?

I believe it's not a trace fossil. The Gastropod is the fossil of the snail or slug-like body.

The palaeontological term for lithified sediments representing the internal cast of a shell is "steinkern" (from the German "stein" for "stone" and "kern" for nucleus).

An "ichnofossil" (derived form the Greek "ikhno" for "trace") represents the biological activity of an organism, not the organism itself; such as a footprint/movement trace, a burrow, boring hole, feeding trace or whatever.
