Generation I and III

In the Generation I and III games, the Dome Fossil is a Key Item.

In Pokémon Emerald, the Dome Fossil (as well as the Helix Fossil and Old Amber) is found in the game data, but it is not legitimately obtainable and has no effect. The player is unable to regenerate this fossil in the Devon Corporation.

Generation IV onward

From Generation IV onward, the Dome Fossil is no longer a Key Item, and is a normal item. Therefore, multiples of them can be obtained, they can be held, and sent to other players via trading.

The Dome Fossils in Shell Shock!
A Dome Fossil in A Night in the Nacrene City Museum!

Main series

Dome Fossils were first seen in Shell Shock!. They made up the structure of the island Fukuhara Island No. 4, and were revived into Kabuto in red moonlight, causing the whole island to collapse and sink.

A Dome Fossil made a cameo appearance in Ancient Family Matters! during a visual representation of Roark's love of Fossils in an argument with Byron.

In A Night in the Nacrene City Museum!, a Dome Fossil was first seen chasing Hawes, as he claimed it to be doing, but was later seen safely placed in a display case. Hawes later explained what it was to Ash and his friends. It was later revealed that the Yamask in the Nacrene City Museum was using its move Psychic to make the Dome Fossil float and chase after Hawes after he put its mask in a display case, thinking that it was a replica Yamask mask given to him as a gift from the company that made a Cofagrigus replica after purchasing it from them for the museum.

Main article: Dome Fossil (Majestic Dawn 89)

The Dome Fossil was introduced as a Trainer card in the Pokémon Trading Card Game in the Majestic Dawn expansion, first released in the Japanese Dawn Dash expansion. Although it is a Trainer card, it is played as if it were a Colorless-type Basic Pokémon, meaning the player's opponent takes a Prize card when it is Knocked Out. However, Dome Fossil can't be affected by any Special Conditions, can't retreat, and the player may choose to discard it at any time during their turn. When the player attaches a Fighting Energy from their hand to the Dome Fossil, they get to search their deck for a Kabuto that evolves from a Dome Fossil and put it on top of it. Afterwards, the player shuffles their deck.

During the XY Series, the Fates Collide expansion included the Item card Dome Fossil Kabuto. It allows players to look at the bottom seven cards of their deck, reveal a Kabuto they find there, and put it onto their Bench. The other six cards are then shuffled back into the deck. The Scarlet & Violet Series saw the release of Antique Dome Fossil in the 151 expansion. This card is similar to the original Dome Fossil, as it is played as a Basic Pokémon, evolves into Kabuto, can't retreat, is not affected by Special Conditions, and may be discarded at any time during the player's turn. In addition, it takes 30 less damage from attacks.

Dome Fossils are also featured on the Mysterious Fossil and Buried Fossil cards. Both of these cards are played as if they were Basic Pokémon and can evolve into Kabuto. Unidentified Fossil does not feature a Dome Fossil, but can also be used to evolve into Kabuto.
