Where do you get fossils turned into Pokémon on white?

You can't turn fossils into Pokémon in Pokémon White.

This feature was introduced in Pokémon X and Y. In those games, you could find fossils and take them to a specific location to revive them into Pokémon.

In Pokémon White, you can find fossils, but they are purely collectible items with no other use.
