Fossil Fighters: Champions

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 found in this Dig Site[]

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

Trivia[]

  • Fossils will sometimes be generated beyond the prompt for the battle with Cole, even though there is no visible way to reach them. This area beyond the prompt can only be accessed by downloading the "Sea" message card DLC rock via Bonus Data through the use of fan-operated services, after which you can visit this area through the Fossil Cannon after completing the main story.
  • The only way to dig up the body, arms, and legs for Archaeo is in the Seabed Cavern.
  • This is the only dig site that can't be returned to without DLC.
  • Discovered in late 2021 by Discord user Pumick, it was found that you could return to Seabed Cavern via the Fossil Cannon. The DLC includes the message: "The (Sea) Message Card was inside. It shows a map of a special dig site." when picked up off of the lawn.https://youtu.be/YkcwirWkxqE
