The only way to obtain Aerodactyl in Ruby, Sapphire, or Emerald is to trade it from another game.
You can't catch Aerodactyl you have to get its fossil at the Pewter City Museum (it's called Old Amber) then bring that fossil to Cinnabar Island where they'll give you the Aerodactyl.
Im pretty sure you dont catch aerodactyl in heartgold but I think you can get him as a fossil, if you do, talk to the guy in the pewter city mueseum and he will turn it into aerodactyl for you.
You need firered or leafgreen to trade you one.
You don't, you have to trade Aerodactyl from FRLG

Neither the Helix Fossil nor the Dome Fossil will become an aerodactyl. In order to obtain an aerodactyl you must revive a pokemon from the Old Amber item which can be obtained in the Pewter City Museum.
