What Pokemon fossils are there on Pokemon black and white 2?

Answer 1

After the hall of fame, you can go to Nacrene city at the Nacrene City Museum and Lenora will let you choose between a cover fossil which becomes Tirtouga, or the plume fossil which becomes Archen. Also after the hall of fame, go to twist mountain lower level 1 and talk to a worker and he will give you one of these fossils per day: helix fossil(Omanyte), dome fossil(Kabuto), Old amber(Aerodactyl), root fossil(Lileep), claw fossil(Anorith), skull fossil(Cranidos), or armor fossil(Shieldon). To revive the fossils talk to the receptionist on the east side of the entrance to the Nacrene City Museum and she will revive them all at Lv. 25.
