Salada- A secret Boneysaur that can only be obtained post-game. The "Bone" Message will unlock an initial sidequest for the player to undertake, however, the specific quest that allows the player to obtain Salada can only be completed after the credits have rolled. Released on January 16, 2012.
- The "Mystery" Element in the Fossil Fighters: Champions Website's Fossil Museum contains all the Bonus Data Vivosaurs, despite them belonging to different elemental groups. There are many "empty" spaces left, though it is unknown what purpose these spaces will serve.
- There are no Fire or Earth Vivosaurs released through Bonus Data.
- Upon inspecting the "Mystery Vivosaurs" page of the official site, inspecting the HTML of the page will reveal that the site contains information pertinent to Duna in particular, mentioning her "Length", "Favorite Food", and "To Obtain", similar to Igno and Frigi. However, none of this information appears on the page itself.
