Armor Fossil

The Skull Fossil (Japanese: ずがいのカセキ Skull Fossil) and Armor Fossil (Japanese: たてのカセキ Shield Fossil) are Fossils which can be regenerated into Cranidos and Shieldon, respectively.

In the games

In Diamond, Pearl, and Platinum, they can be found by mining in the Underground. Skull Fossils are exclusive to Diamond while Armor Fossils are exclusive to Pearl. In Platinum, only one or the other will be found based on the last digit of the player's Trainer ID number; an odd number (1, 3, 5, 7 and 9) will only generate Skull Fossils, while an even number (0, 2, 4, 6 and 8) will only generate Armor Fossils. If brought to the Oreburgh Mining Museum, the Skull and Armor Fossils can be regenerated into Cranidos and Shieldon, respectively.

Unlike the other Fossils, the Skull and Armor Fossils cannot be found by smashing rocks in Pokémon HeartGold and SoulSilver. However, if traded to HeartGold or SoulSilver and brought to the Pewter Museum of Science, the Skull and Armor Fossils can be regenerated into Cranidos and Shieldon, respectively.

In Black, White, Black 2, and White 2, a Worker in the Ice Rock room of Twist Mountain hands out a random Fossil from previous generations, including the Skull and Armor Fossils, once per day. If brought to the Nacrene Museum, the Skull and Armor Fossils can be regenerated into Cranidos and Shieldon, respectively.

Rocks purchased in Antique Shops of Black 2 and White 2's Join Avenue may contain Skull or Armor Fossils.

In Pokémon X and Y, both can be found in the smashable rocks in Glittering Cave.
