I was splitting some basal Greenhorn Limestone, and came across this unusual formation. It appears about the size and shape of some of the bilvalves found here. At first I thought it was modern plant material, but it was in solid rock. Under the microscope, it looks like a crystaline structure. Probably just some mineral crystals that replaced a bivalve, but not real sure. Anyone have any other ideas?

I don't know. Never seen anything like this before. I suppose it could be some kind of sponge or "Sponge-like-creature".

Very interesting.

Could it be something like boxwork?

Context is critical.
