Re: Volcanic rock or what is it?
Did not see any fern fossils in the pictures provided but the "rock" looks like a piece of Pumice. How hard is it? Do a scratch test on a couple of areas with a fingernail, if the fingernail scratches it it's probably pumice. The fact that it is full of holes/ pockets realy make it appear to be volcanic, maybe someones discarded barbecue rocks. Doe's it smell like burgers and hotdogs? How big is it? More than 2 inches and it's probably not a discarded barbecue rock.
