Fossil Fools (Japanese: こだいポケモンパーク!アルフのいせき!!Ancient Pokémon Park! Ruins of Alph!!) is the 163rd episode of the Pokémon anime. It was first broadcast in Japan on September 7, 2000 and in the United States on September 15, 2001.
Spoiler warning: this article may contain major plot or ending details.
One of the clay artifacts that is displayed in this episode also appeared in Me, Myself and Time, over 3 and a half years later and again in Bucking the Treasure Trend!, over 9 and a half years after its original appearance in this episode.
The Ruins of Alph in the games is entirely different and focuses on the Unown.
Archaeology currently dates the first Pokémon at 2 million years ago, though a Kabutops fossil had been discovered that is 20 to 30 thousand years older than that.
Like life on Earth, the prevailing theory is that Pokémon life began in the sea.
The English title is a pun on fossil fuels, a source of energy.
This is the first time Brock takes Misty by the ear.
This episode revealed the scientific name of Kabutops, Kabutops Maximis. The only other Pokémon with a confirmed scientific name is Oddish, whose scientific name is Oddium Wanderus.
Music from the second movie can be heard in this episode.
In the dub, when Ash tells Pikachu to use Thunderbolt (and when Misty points out that the Omanyte and Omastar would get shocked as well as Team Rocket), he says, "Pikachu, use Thunderbolt, Pikachu!" which is redundant as he says "Pikachu" twice in the same sentence.
