Cover Fossil

The Cover Fossil (Japanese: ふたのカセキ Lid Fossil) and Plume Fossil (Japanese: はねのカセキ Wing Fossil) are fossils which can be regenerated into Tirtouga and Archen, respectively.

In the games

A Backpacker of the first floor of Relic Castle has found both of the fossils, but claims they are too heavy and offers one of the fossils to the player, and the player must choose one of the two fossils. The fossil that is not chosen is kept by the Backpacker, and cannot be obtained in-game.

If brought to the Nacrene Museum, the Cover and Plume Fossils can be regenerated into Tirtouga and Archen, respectively.

The item description for the Cover Fossil states "A fossil of an ancient Pokémon that lived in the sea in ancient times" and the item description for the Plume Fossil states "A fossil of an ancient Pokémon that flew in the sky in ancient times. It appears to be part of its wing."

Trivia

• While the item description for the Plume Fossil states the fossil came from a "Pokémon that flew in the sky", the backpacker who gives the fossils mentions that the Plume Fossil is from a Pokémon that lived in an ancient forest, but could not fly.
