When and where I can "revive" fossils?

Question

I trade pokemon with my friend and the pokemon is holding Helix Fossil. I want to revive it!

Answer 1

In Pewter City in the Kanto Region there is a Fossil revive building. This is also the same city in which battle Brock and Can obtain the rainbow wing(In SS).
