In the anime, the appearances of Fossilized Fish and Drake are swapped, making them match the Pokémon they are supposed to restore.
Trivia
In Pokémon Sword and Shield, the Fossilized Fish and Fossilized Drake appear to have mistakenly swapped sprites. The Fossilized Drake offers the "Draco-" body for Dracozolt and Dracovish but visually looks like the head provided by the Fossilized Fish. In the anime, their appearances are the opposite of their game sprites.
The Pokémon revived from the Fossilized Drake have 10 fewer points in their Special Attack and Special Defense stats, and 20 extra points in Speed, compared to their counterparts revived from the Fossilized Dino.
