5 fossil PokémonGen 3 · KantoUpdated NOV 12, 2026

Fossil Pokémon in FireRed & LeafGreen

FireRed & LeafGreen carry 5 fossil Pokémon. Super Nerd Miguel guards the Helix and Dome Fossils on Mt. Moon B2F, and beating him lets you walk off with one. Old Amber is a scientist’s gift once Cut opens a path to the museum’s back door in Pewter. Cinnabar’s lab revives each one at Lv. 5.

The list

All 5 fossil Pokémon in FireRed & LeafGreen, across 3 fossil lines

Your pick at Mt. Moon decides if you revive Omanyte, which grows into Omastar, or Kabuto, which grows into Kabutops, so a FireRed or LeafGreen save holds one shell line beside Aerodactyl.

Where to find them

How to find and revive every fossil in FireRed & LeafGreen

Miguel keeps whichever fossil you pass over, so settle on a line before you grab one. Both finds then ride in your bag until the lab on Cinnabar Island.
