Hmm... Is it because fossils are undoubtedly damaged due to the conditions for making pyrite? Something something intrusion?
Pyrite disease! The pyrite oxidizes in humid air, converting to a mineral that takes up much more volume. If the pyrite is incorporated into the fossil matrix, that expansion causes the fossil to crumble.
Tbh I've always wanted to find a pyritized fossil. So cool.
You can find pyrite fossils in Pennsylvania as well, surprisingly.
