The Jaw Fossil (Japanese: アゴのカセキJaw Fossil) is a Fossil introduced in Generation VI that can be regenerated into Tyrunt. It is the counterpart of the Sail Fossil.
The Jaw Fossil was introduced as an Item card in the Pokémon Trading Card Game in the Furious Fists expansion, first released in the Japanese Rising Fist expansion. It allows players to look at the bottom seven cards of their deck, reveal a Tyrunt they find there, and put it onto their Bench. The other six cards are then shuffled back into the deck.
Unidentified Fossil cards are Fossil Trainer cards which become Basic Pokémon. While they do not feature a Jaw Fossil, they can still be used to evolve into certain Tyrunt.
