Where To Find Fossils

Fossils. There are easy ways to get them. If you want Archen or Tirtouga, go in the Relic Castle, and talk to the Hiker. (To get through the quicksand, just walk.) You have a choice between the Cover Fossil, Tirtouga, and the Plume Fossil, Archen. Take the one you want. For everything else, obtain the National Pokedex and go deep into Twist Mountain. Eventually, you will find a Worker that gives you a random Fossil. He gives you a Fossil every day. When you find a Fossil, you can bring it to the Nacrene City Museum, and if there is an open slot in your party, you will have that Pokemon, at Level 25. Fossils always evolve at Level 40, if you want it evolved.
