Fossil Pokémon in Red & Blue

Red & Blue have 5 fossil Pokémon. Beat the Super Nerd on Mt. Moon B2F and take the Helix Fossil for Omanyte or the Dome Fossil for Kabuto, never both: he keeps the other. A Pewter Museum scientist gives Old Amber, for Aerodactyl, after Cut clears a way to the back door.

The list

All 5 fossil Pokémon in Red & Blue, across 3 fossil lines

The Helix Fossil revives Omanyte, which evolves into Omastar, and the Dome Fossil revives Kabuto, which evolves into Kabutops. Your Mt. Moon pick allows one line per save, while Old Amber gives everyone Aerodactyl.

Where to find them

How to find and revive every fossil in Red & Blue

Hold on to what you collect: nothing gets revived until the Pokémon Lab on Cinnabar Island. And think before you choose at Mt. Moon, since the fossil you leave stays with the Super Nerd.
