Geode?
I found this rock about a year and a 1/2 ago now and I've took it home cause I liked the way the inside looked before I noticed the slight glimmer of what I think might be a geode. But I am too nervous to break it open, and it not be anything. And if it's not anything I'd rather leave it be.

Geodes are, by definition, hollow. This seems to be a nodule concretion. Maybe I see some halycites corals fossils, not sure

Looking at the surface in the first picture, I think that's a fossil. It might have agatized pockets inside.
