Seabed Cavern

Seabed Cavern (海底どうくつ Seabed Cave) is a Dig Site in Fossil Fighters: Champions.

Seabed Cavern is the only Dig Site in Fossil Fighters: Champions that is not permanently available; once the Hero defeats Cole and re-calcifies the Spinal Pillar, they can no longer access it. The Hero can visit it any number of times before completing its storyline events. (Warning, it is extremely recommended that the player collect every possible fossil before fighting Cole because afterward, only the head fossils can be found at the other Dig Site and even then they are extremely rare).

Story Significance
The Hero visits the dig site in order to prevent the sinking of the Caliosteo Islands by injecting the Spinal Pillar with calcium obtained from the Sardinasaurus fossil found in Petrified Woods. When the Caliosteo Patrol Team discovers the B.B. Brigade have sabotaged the submarine intended to bring them to the Seabed Cavern, they are instead forced to use the Bonehemoth to reach the site.

While diving, Robinson tells the group that there are three entrances to the Seabed Cavern, one below each of the three islands. Pauleen and Rupert exit the Bonehemoth at the Cranial and Ilium entrances, leaving the hero to enter underneath Ribular Island.

There the Hero again encounters Cole, along with two B.B. Brigade members chipping away at the Spinal Pillar with picks. While surprised to see the Hero, Cole engages them in battle to stop any further interference.

After defeating Cole, the Hero promptly injects the calcium into the Spinal Pillar, which quickly returns to its normal size.

Vivosaurs
(Note: Seabed Cavern will yield Silver Heads when Wondrous Fossil Rocks are excavated.)

All fossils found in Seabed Cavern can very rarely be found in other Dig Sites.

Trivia

 * Fossils will sometimes be generated beyond the prompt for the battle with Cole, even though there is no way to reach them.
 * The only way to get the body, arms, and legs of the special Vivosaurs is in the seabed cavern.
 * While all of the other Vivosaur's fossils can also be obtained through the Fossil Cannon of the first game, Archaeo's other fossils can only be found in this dig site.
 * This is the only dig site that cannot be returned to after the initial visit.
