I am really not convinced that Aerodactyl should be moved out of D-tier at all.

The main reason is some of these sets that are being used are almost all outclassed and I fail to see their merit. When are you ever going to set up a Hone Claws on Aerodactyl with its frality? Why not just use something stronger like Terrakion, which has Swords Dance? Why not just use something with a Choice Band with several Powerful moves, possibly boosted by weather? Why would you ever use Scarf Aerodactyl? Or Taunt plus Roost Aerodactyl? If you're going to go for a fast cleaner... once again Terrakion takes the cake with a Scarf. The second set is outclassed by Crobat most of the time since it has a better bulk and a better defensive typing (and Brave Bird so it hits harder) and it isn't even that good in OU to begin with. Aerodactyl only has two advantages over Terrakion - a immunity to Earthquake and the ability to outspeed a lot of Pokemon that Terrakion cannot. Even then, Aerodactyl's only good offensive move happens to be Stone Edge, which is imfamous for missing every five seconds for a very good reason. Earthquake is OK but it is getting to be unrelaible. 105 Base Attack to go alongside this move makes it a rather below average physical attacker, especially when you consider that there are many Pokemon packing 120 Base Power STAB moves with perfect accuracy, technical double STAB with weather, a higher attack stat with dual STABs (Aerodactyl has no good Flying moves), or more than one of these!

Aerodactyl is only worth using in OU if you are going to lay down a fast Stealth Rock, and even then, there are many other options for setting up the move - most of the time Deoxys-D does a better job than it, which is what makes it worthy for D-tier, where it is now.
