No it's not just a rock..it's a chunk of fossilized shiny tabulated coral, duh.

Tabulated Coral fossil found in the privately owned shale pit near my home place in Western Maryland. I have found hundreds of horn corals, crinoids, bryozoan, etc. from there. Full slabs of visible 100-500 million year old coral reef beds just waiting to be found. Within each different layer of rock majority of the fossils I've found are just filled with shiny bits. I'm not sure if it's agatized, quartz, some other type of mineral? Can y'all help a girl out?

Looks like a Favosites  sp. with some calcite crystals inside.

So I guess my question is..is it worth cutting in half?
