In Pokémon Shining Diamond and Shining Pearl, directly north of the Ore City Pokémon Center is the Ore City Mining Museum. Talk to the scientist on the right side of the desk. Once you have access to the Grand Underground, you can bring it fossils. He will revive your fossils in one of seven Pokémon. We tell you which fossils turn into which Pokémon.
Omanyte is a rock / water Pokemon that is brought back to life by the Helix Fossil. Evolves into Omastar at level 40. His Swift Swim ability makes him perfect for rain squads.
Kabuto is another rock / water Pokemon that is brought back to life by the Dome Fossil. It evolves into Kabutops at level 40. Kabutops is the physical attack equivalent of Omastar, who excels at special defense and attack. He is another great Swift Swim user.
Aerodactyl revives from Old Amber and has been a powerhouse since the first generation. Aerodactyl is rock / flying and hits hard and fast. You can't go wrong with this on your team.
Lileep comes from the Root Fossil and has a unique type of rock / grass. Like other fossil Pokemon, it evolves at level 40 into Cradily. Cradily's hidden ability, Storm Drain, is perfect for predicting enemy plays. She activates Cradily on water attacks and you get an instant special attack boost.
Anorith is from Claw Fossil and evolves into Armaldo at level 40. It has a rock / bug type and has strong attack physical and defense stats.
Cranidos, from Skull Fossil, evolves into Rampardos at level 30 and has a pure rock type. He has one of the highest attack stats of non-legendary Pokémon in the entire game. Rampardos has the hidden ability, Sheer Force, which increases the damage of moves with secondary effects at the cost of those effects.
Shieldon, from Armor Fossil, evolves into Bastiodon at level 30 and has a rock / steel type. Keep it away from ground attacks and this high defense and special defense wall can keep your other Pokémon safe.
