Vivosaurs are the basis of Fossil Fighters. Vivosaurs are prehistoric creatures revived from fossils by alien qq and are friendly towards humans. Vivosaurs have taken several traits from their foundation ground, and as such are no longer true prehistoric creatures, but a transformed version of of their counterparts.  Their names are shortened versions of the scientific names of the animals they were. Vivosaurs can be carried around as Dino Medals, with a team of up to five at a time, but only three can fight at once. There are more than 100 vivosaurs, over 140 in Fossil Fighters: Champions, along with several 'special' legendary creatures. Once a Vivosaur has maxed battle points fossil, its medal will turn golden. In Fossil Fighters: Champions, Vivosaurs can "Super Revive" and become more powerful by being integrated with a Wondrous Fossil or Miraculous Fossil. A Wondrous Fossil can possess different parts while a Miraculous Fossil only contains a golden head. The golden head in a Miraculous Fossil can be used on any vivosaur but only a few can, as mentioned earlier, Super Revive into a special Vivosaur. The different parts that a Wondrous Fossil are obviously the known four: Head, Body, Arm, and Legs. The super revival will change your vivosaur's color and make it stronger. For example: The normal T-Rex is red and black but if a silver fossil is used on it, it will change color, depending on the type of silver fossil used.


Vivosaurs can be one of 6 types: Fire, Water, Earth, Air, Neutral, and the rare Legendary element, which only the three brains of Guhnash (guhvorn,guhlith, and guhnash), Frigi, Igno, Zongazonga and the zombiesaurs (z-saurs) have unlike the boneysaurs. All elements have a weakness and strength against another element, but the Neutral and Legendary elements have none.

Fossils rocks contain parts of a vivosaur, the Head, Body, Arms, Legs, or complete skeletons. Complete skeleton fossils can only be found in Fossil Fighters: Champions within the Giant Fossil Rocks. A vivosaur only needs a Head fossil to be revived and used in battle, but will not have all of its skills until it gets to around rank 5-7 or by getting all of its parts found, cleaned and integrated. However, in Fossil Fighters: Champions, vivosaurs learn skills at rank 1, 3, 5, and 7. Fossils are taken to the Cleaning Room in the Fighter Stations to be cleaned and integrated into already revived vivosaurs or to be stored until the head is found. Be careful while cleaning a fossil as it can get damaged, especially with a hammer. Any fossil that is a body, arms, or legs can be integrated into the vivosaur it belongs to, thus making it stronger overall. Sometimes you will find rare red-boned fossils. These fossils will add 25 points when you clean them if it is successful (this is especially helpful when the fossil has low points). The max points a fossil can have is 125, as a result, the max points a Vivosaur can have without battling is 500, meaning all 4 fossil rock cleanings were red-boned and perfect, but this only applies to the first game, Fossil Fighters, the second game however, has a max rank of 20 on vivosaurs and the fighter. The only way to revive a vivosaur is to find that vivosaur's respective head. There are other fossils rocks, called jewel rocks, which can be sold at the shop for a decent price especially if cleaned perfectly, and coprolites (Dropping fossils), which can be given to Nick Nack in his hotel room or John Guano within the Hare Club in Cranial City on the left of the Fossil Guild. Selling a dropping fossil to the Fossil Guild will only give you 1G so it isn't worth the effort to go and sell it. A sandal fossil can also be found in Greenhorn plains, but only once, and it is part of the storyline as an object that has to be traded to Nick Nack with the molted bug shell and the Denture Shark Dentures for Captain Woolbeard's Beard Ribbon.

Special Vivosaurs

There are vivosaurs that are obtained in a way other than fossil digging, buying from the guild, Donation Points, and etc. You may have to battle for them or achieve something. They have max battle points when you receive them but there are no bones required which is good if you don't like fossils that aren't 100-125 points as it could be anything. The specials are:

  • Dinomaton (revive all 100 original vivosaurs)
  • Duna (revive all 100 original vivosaurs)
  • Raptin (revive all 100 original vivosaurs)
  • Dynal (battle Dynal, Duna, and Raptin in a battle at the starport)
  • Frigi (beat the BB bandit trio)
  • Igno (beat Saurhead the 3rd time in 3 matches)
  • Guhnash's Brains (Beat Gunash in time warp post-game)

The ways to obtain the special vivosaurs above only take affect after you have beaten Gunash.

There are 5 others that are known as the Chickens. This family is obtainable two different ways one being via Nintendo Channel and their eggs only be downloaded once per game.You can also get all of them with max battle points if you have every Vivosaur at Rank 12.(Fossil Fighters only).

In Fossil Fighters: Champions, all of these except the 3 brains are available via the Bonus Data option in Multiplayer while connected to Nintendo Wi-Fi Connection. You can also obtain the Chickens in different sidequests.

Fossil Battling

Once revived, you can use a vivosaur in a Fossil Battle. Their stats show how well they will do in battle. Their stats are:

  • LP (Life Points): Determines the damage a vivosaur can take before being defeated, basically health.
  • Attack: Determines the damage dealt by the vivosaur.
  • Defense: Determines the reduction of damage to the vivosaur. It may be possible to determine the damage taken in a specific skill: vivosaur defense/max defense (54). Change that into a fraction of the skill in question. For example, vivo defense is 27, max is 54. Fraction is 9/18, or 1/2. So, if skill attack is 100, one half of 100 is 50, and that is the damage the vivo will take.
  • Accuracy: Determines the chance of hitting the target vivosaur. Some vivosaurs have very low accuracy, needing support effects to make them effective, i.e. Zino or Centro.
  • Evasion/Speed: Determines whether the vivosaur can evade an attack, and (Fossil Fighters Champions only) whether it will attack first.

All of these except for Life Points can be increased or decreased with another vivosaur's Support Effect in battle. A support effect can be applied to either AZ on the field. Some Vivosaurs have no support effects.

The AZ (Attack Zone) and SZ (Support Zone) are where the vivosaurs are when a battle starts. The AZ is where a vivosaur can receive and deal the most damage on the field. A vivosaur in the AZ can attack the enemy AZ and SZ. The SZ is where a vivosaur's Support Effect (if it has one) is applied to the AZ. While in the SZ, a vivosaur receives less damage from attacks, but also deals less damage (though Long-Range class vivosaurs do not get this attack penalty). SZ vivosaurs can only attack the AZ. The EZ (Escape Zone) is where a AZ vivosaur goes when it is switched with a SZ vivosaur, or is knocked there by certain attacks. It cannot attack or recieve damage when in the EZ. Vivosaurs automatically move out of the EZ and into the SZ after two turns. In Fossil Fighters Champions, there is no EZ, and you can switch all you want. Also there does not have to be a vivosaur in the AZ.

The skills a vivosaur needs to perform requires a certain amount of Fossil Points to be used in battle. These are recharged automatically at the beginning of a turn by a certain amount, determined by the Fighter's Rank. A small amount of Fossil Points can be added by certain abilities, such as FP Plus or by having a vivosaur use the Power Scale skill.

Once a vivosaur has no Life Points left, it is eliminated from the battle. If it was in the AZ, a vivosaur from the SZ takes its place. (This does not occur in champions) The side with the lowest total LP goes first, this is changed in Fossil Fighters: Champions whereas the team with the most speed goes first.

Vivosaurs have Skills and Team Skills. New skills are learned by a vivosaur after ranking up to the ranks mentioned in the Fossils category above Donation Points category in this post. Team skills are already known by a vivosaur in the original fossil fighters regardless of rank or number of fossil parts. Team skills are usable when the team has three vivosaurs on the field that share a common trait, example, diet, element, location, and time period. In Fossil Fighters: Champions, it is also possible to use a Team Skill by having three vivosaurs being different elements, each. Team Skills attack both the AZ and SZ on the opponent's side of the field. The pros and cons of Team Skills are that even though it attacks the whole enemy team, it does less damage than it does on a single vivosaur.

Names in other languages

  • Japanese : リバイバー Reviver
  • French: Vivosaures
  • German: Vivosaurier
  • Spanish: Vivosaurios
  • Italian: Vivosauri
  • Korean: 리바이버 Ribaibeo


  • Vivosaur is a combined word. "Vivo" translates to 'living' in Latin, and 'saur' translates to reptile/lizard. The word formed by joining the two words literally means 'living reptile'.
  • It should be noted that, despite the addition of two new Japanese Vivosaurs in Champions, Toba and Gaudry, neither one can use their team skills with any of the original three Japanese Vivosaurs, F-Raptor, Futabi and Mihu. Thus, using either of the new Japanese Vivosaurs with one or two of the original three renders the original three's team skill unusable.
  • Some vivosaurs have incorrect in-game features. For example, the real Mamenchisaurus didn't have a wrecking ball for a tail.
  • For some odd reason, both games had a suprising twist in the form of the chicken "vivosaurs" that were not really vivosaurs.It is for that reason that the chickens are characterized as mysterious vivosaurs in the Fossil Museum and the Fossilary.
  • In FF, the player's starter will always be a Spinax. However, in FFC, the player can choose one of four unique vivosaurs for their starter: Tsintao (earth), Toba (water), Dimetro (fire), or Aeros (air).
  • The Spinax in FF must be cleaned and revived. In FFC, the starter is already revived, but it is still at rank 1.
  • All starters have a super evolved form. FF: Spinax (Giga Spinax) FFC: Tsintao (Bulgon), Toba (Equinas), Dimetro (Lugmos), Aeros (Teffla).
