Oakley brought both Aerodactyl and Kabutops back to live by using the Defense Mechanism of Alto Mare. She used them to locate Latias and to bring her here. They found Latias but Ash interfered and tried to escape from them with Latias. Aerodactyl used Hyper Beam to stop them but Ash's Pikachu used Thunderbolt to counter the attack. After Latios was released from the Defense Mechanism, both Aerodactyl and Kabutops were transformed back to fossils.
