Helix Fossil

The Dome Fossil and Helix Fossil are fossils which appear in the Generation I games, their Generation III remakes, and in the Generation IV games.

These key items are found in Mt. Moon after defeating a Super Nerd. Players are allowed to choose only one, as the other one will be taken by the Super Nerd. If brought to the laboratory on Cinnabar Island, the Dome Fossil can be regenerated into a Kabuto, and the Helix Fossil can be regenerated into an Omanyte. The Pokémon extracted from the Super Nerd's fossil is seen in the zoo just outside the Safari Zone.

In the anime, Dome Fossils are seen in Shell Shock. They make up the structure of an island, and are revived into Kabuto in red moonlight, causing the whole island to collapse and sink.

Both fossils appear on the artwork for the Mysterious Fossil card. However, the artwork depicts the Dome Fossil as the fossil of a Kabutops rather than a Kabuto.

The fossils are also available, like the Claw and Root Fossils, in Sinnoh's Underground. Helix Fossils are more common in Diamond while Dome Fossils are more common in Pearl.
