Fossil

"Fossil" (化 (か) 石 (せき) Kaseki) is an archetype consisting of EARTH Rock Fusion Monsters used by Jim Crocodile Cook in the Yu-Gi-Oh! GX anime. They focus on a unique form of Fusion Summoning via "Fossil Fusion". In the anime, they are summoned by banishing a Rock monster in your Graveyard and another Type of monster from your opponent's Graveyard. "Fossil Fusion" supports the archetype, which results in several other cards that have been released being part of this archetype.

This archetype debuted in "Collection Pack 2020" in the OCG and "Battles of Legend: Armageddon" in the TCG, after topping a January 2020 poll conducted by Konami.

In the Japanese version, the "Fossil" Fusion Monsters have power that each correspond to their age. The older the monster, the more powerful it is. Name-wise, they have prehistoric eras in their names, which were removed in the dub and English video games.
