Where do you get aerodactyl in Pokemon?

Answer 1

I can trade you one!

You just have to find an Old Amber fossil in the underground mines. Once you find one go to the Oreburgh City Museum, talk to the person standing behind the counter, and last of all have him revive your Old Amber fossil.

Another Person, another answer.

You don't have to trade with him/her.( This answer is only for soul silver/ heart gold.) You go to the Ruins of Alph, and you use Rock Smash on smash-able rocks until you get a Old Amber Fossil. Then you go to the Pewter Museum and talk to the guy that's sitting in front of a PC. Revive your fossil. Come back within half an hour, and WA LA. A aerodactyl. If you want a girl one, you get save next to the guy and soft reset your Ds if it isn't a girl.
