Trivia

In the first season of the anime and during much of Generation I, the Rock type was often wrongly assumed to be unaffected by Electric-type attacks. This was likely due to the fact that at the time, most Rock-type Pokémon (namely the Geodude and Rhyhorn evolution lines, and Onix) were part Ground-type and thus immune to Electric-type moves. However, the only non-Ground Rock-type Pokémon around at the time (the then five Fossil Pokémon) were actually weak to them.
The Rock type is tied with the Grass type for the largest number of weaknesses when unpaired, with five. However, a combination of the two types (Rock/Grass) would only have four weaknesses.
Rock moves are super effective against four of the five types Grass is weak to, with Poison being the exception.
Every known Fossil Pokémon is part or solely Rock-type. This is most likely due to the placement of real fossils in rock formations, as well as the process by which fossils are created.

Rock is the only type whose positive offensive matchups outnumber its negative offensive matchups without one of said negative matchups being an immunity.
