Shieldon (Japanese: タテトプス Tatetops) is a dual-type Rock/Steel Fossil Pokémon. It is resurrected from an Armor Fossil and evolves into Bastiodon starting at level 30.
Shieldon is a small, ceratopsian-like reptilian Pokémon with a yellow body. It has white toes and bears a white bump on its back. Shieldon has a dark-gray oval-shaped face, with a prominent brow that is white in coloration and a white rim on their black snout. Shieldon may be ancient relatives to the Aron line due to identical typing and partially similar movepools, especially the ability to learn Metal Burst.
