It is resurrected from an Old Amber and is not known to evolve into or from any other Pokémon.
A ferocious, prehistoric Pokémon, it possesses serrated, saw-like fangs that it uses to tear through the throats of its prey. Its wings have light purple skin stretched from its side to its arms. It has a gray, oval-shaped body, and a tail with a triangular tip. Aerodactyl have dark green eyes, though the iris is barely visible.
Aerodactyl is capable of flying at great speeds and tearing through prey with its fangs. Aerodactyl also shows some form of relationship to dragons, thus allowing it to learn Dragon- and Fire moves such as Dragon Claw, Fire Blast, and Flamethrower.
Aerodactyl's preferred method of killing its victims is by tearing through their throats with its serrated, saw-like fangs.
The exact habitat of Aerodactyl is unknown. Even though living samples have been found underground in caves, so far most Aerodactyl are revived from Old Amber. It most likely lived in mountainous areas.
Aerodactyl's hard fangs suggests it might be a carnivore. Its sharp claws are probably used to capture prey. They seem to, though, enjoy eating pear-like fruit which grew in the forests of an island, hence implying that it may be an omnivore.
This Pokémon was unavailable prior to Generation I.
