ITT: Ancient Pokémon. (Not to be confused with fossil/prehistoric Pokémon.) I noticed that a few Pokédex entries mention ancient human civilizations, so I've tried to collect them all together. Have I forgotten any?

Unown: "Their shapes look like hieroglyphs on ancient tablets. It is said that the two are somehow related."

Claydol: "It is said that it originates from clay dolls made by an ancient civilization."

Bronzong: "Ancient people believed that petitioning Bronzong for rain was the way to make crops grow."

Sigilyph: "The guardians of an ancient city, they always fly the same route while keeping watch for invaders."

Golurk: "It is said that Golurk were ordered to protect people and Pokémon by the ancient people who made them."
