Bastiodon

Bastiodon is a dual-type Rock/Steel Fossil Pokémon.

It evolves from Shieldon starting at level 30, after it is revived from an Armor Fossil.

Biology
Bastiodon is a Pokémon which appears to be a cross between a ceratopsian such as Zuniceratops and a bulldozer. Its dark gray, square head resembles a castle wall, complete with four cream-yellow, window-like spots with a black outline, three dark gray spikes on the top, and two larger gray spikes in the upper corners. Bastiodon's triangular nose extends from the middle of its shield-like head down over its lips and appears to be pierced by a gray, horizontal spike. Four spikes jut downward and four large, blunt tusks protrude upward from its dark gray lower jaw. Bastiodon's cream-yellow eyes are partially obscured by the nasal spike and spaced-out tusks. Its thick, cream-yellow body is further protected by a gray ridge and dark gray plates on its back, jagged growths on its legs, and a plated tail.

It is from roughly 100 million years ago. Despite its rough, intimidating appearance, Bastiodon is actually a docile, caring Pokémon that feeds on grass and Berries. Its steel-hard, shield-like face is capable of repelling any attack. When multiple Bastiodon line up, their faces form a wall that nothing can break through; this was how they protected their young. In stark contrast to its impenetrable frontal defense, it is vulnerable from behind. It seems to have lived in the same habitats as Rampardos, as evidenced by their fossils often being found together.
