I 've got a Skull fossil which I revived into a cranidos and a cover fossil which I revived into a tirtouga. What are all the other fossils I can get?
In Gen 5, a person in the Relic Castle will give you a Cover or Plume Fossil. The others can be obtaibed from a worker in Twist Mountain who will give you any of the older Fossils daily.
Revive the Fossil into a Pokemon at the Nacrene City Museum.
