Sounds like a cool idea, but just remember: bone fragments need their own layer, not just a random pile of plastic and cracked plates. If you can keep the fossils in the correct stratigraphic order and then frame them with the reclaimed wood, it’ll look like a real fossil cross‑section. Just make sure you have a steady hand and a good glue—no sloppy messes. And maybe keep the kitchen scraps away from the actual fossils; they’re not the same kind of relic. Good luck!
