Piper,

Limestone IS a form of fossil made up of very small skeletal structures of dead critters. Often within the mass of very small creatures that make up the majority of a mass of limestone one can find larger representatives of once living organisms. I have a nice ammonite in just such a setting. Be aware that there are many different types of limestone. Some of it is very hard while other forms are relatively soft. I find the older it is the deeper it has been and more compression has hardened it. Both of the bread "layers" may still be a form of sedimentary rock, as is the "meat". See what I mean about attempting to ID things like this from picts?

I keep an eye on this thread for your reports. There's no rush, at least for me.

I'd contact the Maine geologic survey in the mean time.
