    They will decay within 2 years after hitting oxygen. Solution: Encase them in resin. Source: What I did with these pyrite fossils on my desk.

        I posted some snaps here when I first pulled them out of the ground of this batch. I haven’t polished the resin yet on most of the encased ones, but I’ll post a snap after my phone charges a little bit. I have some fossils that turned into clay, ancient wood fragments and belemnites in there too. All are from the Jurassic Coast in Dorset.

        You can see what happens when the wood gets exposed on the little black one. The big guy is clay.

        One that’s mostly polished up:

        I am saving these for teaching tools. They were collected with help from a good friend of mine that does palaeontology. My research is only Holocene lol.
