Aerodactyl

Aerodactyl is a ferocious perhistoric Pokemon that goes for the enemy's throat with its saw-like fangs. In "Attack of the Prehistoric Pokemon" Ash is confronted with long-thought extinct Pokemon — Omastar, Omanyte, Kabuto, Kabutops and the terrifying Aerodactyl. The pterodactyl-like creature grabs Ash and is about to turn him into a snack — until the newly evolved Charizard rushes to his aid and settles the score with Aerodactyl.
