    I can't see it very well in the lighting, but it looks to be some kind of coral.

    Who're the geologists on here? It looks a lot like honeycomb, in certain ways. Only rocky. And thicker.
    Maybe a marine biologist can weigh in on corals.

    I'm neither; So will vote that it's Archerite. Could get you a pretty penny from the Andorian Mining Consortium.

    Coral was what I was thinking too. But heavier. Does coral petrify?

    I have a master's in geology, but I've never been one for rock ID.

    I don't think coral really petrifies as much as fossilizes. Corals can be heavy, though, depending upon what fills the structure.

    Nope to the honey comb and to the coral, this seems to be an Oolite of some sort. Oolite - Wikipedia, the free encyclopedia

    Do you know where it was found? (Possibly in a limestone cave or karst?)

    I found it on the bank beside my driveway that was covered in stone about 3 years ago. I live in WV., so I'm assuming the stone came from a quarry somewhere in WV. It was bught at a place where stone is brought to

    Just to clarify, it wasn't your photos giving me trouble, I was just outside in the sun.

    I do see what appears to be coral structure in the second pic here, but without handling the sample I just can't give you more than a suggestion.

    Rock ID with a hand sample is really easy if you just perform a few simple tests. You can do a Mohs test with household objects, a streak test on anything light colored and harder than your sample, a specific gravity test with...well...your hands. I've taught 6 year olds to do rock ID, so I'm sure you could handle it.
