Bonus Data

Bonus Data is a form of downloadable extra content for Fossil Fighters: Champions, allowing players access to new vivosaurs, sidequests, characters, and more. Though Nintendo Wi-Fi Connection, the service originally required to obtain the Bonus Data, was terminated on May 20th, 2014, it is still possible to access the extra content through the use of fan-operated services.

Content accessible through Bonus Data
To access the Bonus Data, the player must first have unlocked the Fossil Cannon in Story Mode. Once the player has downloaded the data, fossil rocks, each with either a Dino Medal or an event-related key item attached, will appear on their Fossil Lawn. The player can collect them at any time.

Frigi and Igno Dino Medals
Bonus Data-exclusive vivosaurs Frigi and Igno were released in North America on December 25th, 2011. Each of their Dino Medals can be collected directly from fossil rocks on the Fossil Lawn.

"Dragon" Message Card
The "Dragon" Message Card was released in North America on January 1st, 2012. It can be collected from a fossil rock on the Fossil Lawn and grants the player access to three postgame sidequests (Duna's Due, Raptin's Rage, and Dynal's Debut), through which they can obtain the vivosaurs Dinomaton, Duna, Raptin, and Dynal.

"Bone" Message Card
The "Bone" Message Card was released in North America on January 16th, 2012. It can be collected from a fossil rock on the Fossil Lawn and grants the player access to two sidequests: Ryne's Request and Ryne's Challenge. Ryne's Request can be completed as soon as the player obtains the message card, while Ryne's Challenge is only available in the postgame. Through these sidequests, the player can obtain the Ryne Mask, the Favre and Ryne icons, and the exclusive vivosaur Salada.

"Lake" Message Card
The "Lake" Message Card was never officially distributed in North America. It can be collected from a fossil rock on the Fossil Lawn and grants the player access to an unused area of Treasure Lake via the Fossil Cannon. Fossils for Treasure Lake's rare vivosaurs can be found easily in this area.

Trivia

 * The "Mystery" type in the Fossil Fighters: Champions website's Fossil Museum contained all the Bonus Data vivosaurs, despite them belonging to different elemental groups. There were many "empty" spaces left, though it is unknown what purpose, if any, these spaces were meant to serve.
 * There were no Fire- or Earth-type vivosaurs released through Bonus Data.
 * When the "Lake" Message Card is downloaded from a fan-operated service, the download notification will incorrectly say that the "Bone" Message Card was received instead. The card correctly identifies itself as the "Lake" Message Card when it is picked up from the Fossil Lawn, however.
