Although I agree with Mega Aerodactyl dropping I've done some research, and I think that I can now kind of understand why Mega Aerodactyl was A- Rank in the first place. Sure, it has its flaws that are big enough to deter it from A-, but when you look past that, I see a pretty darn decent Pokemon. It has a wide offensive movepool that is boosted by Tough Claws, making the Elemental Fangs usable, as well as other moves such as Iron Head, Pursuit, Aqua Tail, Aerial Ace, and Crunch. It isn't bad defensively either- it has solid 80/85/95 bulk, and it is still fast enough to outpace much of the meta without substantial investment. It has moves like Taunt, Whirlwind, Stealth Rock, Defog, and Roar to help support its team, so it can run defensively-oriented sets decently. It has lots of flaws, including its EdgeQuake not getting physical contact, and the metagame trends have not been too favorable for it. It's typing permits weakness to SR (which is bad for a defensive mon), and it is particularly hurt by all forms of status, so it shouldn't stay A-. A decent but overrated mon, B+ or B imo.
