Players excavate and clean fossils. New giant fossil rocks (containing complete dinosaur fossils) and odd fossil rocks (which are two-sided) add to the fun of the cleaning process.

Once the fossils have been cleaned, they can be revived into Vivosaurs, which players can then arrange into teams for battles. The better the fossils have been cleaned, the more powerful the Vivosaurs are in battle.

Strategy is key in battles. Players must put forth teams of three vivosaurs, then rotate their positions to maximize their power advantage over opponents.

New “super evolver” vivosaurs evolve into new forms with the help of gold fossils.

Players can compete in matchmaking battles or upload their best team to see how it fares against others. Players can also download additional vivosaurs and events.

Using DS Download Play, one player who has the game can link up wirelessly with up to three other Nintendo DS owners within range and cooperate to expertly clean fossils together.
