This page offers a guide on Pokémon Fossils, including where to get them and what to do with them in Pokémon: Brilliant Diamond and Shining Pearl (BDSP).
What are Pokémon Fossils?
Pokémon Fossils are found when digging for treasure in the Grand Underground. They’re a relatively rare find so you’ll likely have to do a fair bit of digging.
There are several types of Fossils, there are also two Pokémon Fossil types that are version exclusives. The Pokémon fossils can then be taken to Scientiest at the Mining Museum in Oreburgh City. He’ll offer to revive it and all you’ll need to do is leave the Museum and pop back in, and he’ll give you a Level 1 Pokémon that corresponds to the given fossil.
All Pokémon Fossils
