Can Antique Old Amber evolve into the old Aerodactyl ex since it says "evolves into Aerodactly ex" on the card?
No, it cannot. You need to look at the "evolves from" info on the Evolution Pokemon. Aerodactyl ex from Sandstorm evolves from Mysterious Fossil, so it cannot evolve from Antique Old Amber.
