#142 - Aerodactyl
Rock/Flying
Here we are, the final Generation I Fossil Pokemon, and arguably the most popular Fossil Pokemon of all time. Unlike our previous Fossil Pokemon, Aerodactyl is a single-stage Pokemon, and is Rock/Flying instead of Rock/Water. Revived through the Old Amber, obviously a shout-out to the method popularized by Jurassic Park, Aerodactyl appeared late in the Kanto journey, but everyone was able to get his Fossil as opposed to having to chose between it and another. Thus I imagine due to how immediately cool he looked probably quite a few people kicked out whatever Flying-type Pokemon they had in their team in favor of him. In Gold and Silver he was the only Fossil Pokemon available without trading with Generation I, and in quite an odd way---a random NPC had him and would trade you one for Chansey. Aerodactyl looks cool, and has the second highest speed of Generation I alongside Jolteon, but during his debut he was actually somewhat weak, due to having a very poor move set with no Rock-type moves, and rather poor Flying-type moves like Fly and Sky Attack which were easy to predict and left him open to being countered. However, he quickly picked up steam when he began to receive better moves, and in Generation IV gained notoriety for being one of the fastest Stealth Rockers. Apparently, though, his main strength was unpredictability, and the mandatory team preview introduced in Generation V greatly hurt him, as if you knew he was coming, he's apparently east to predict. But he got a Mega in the next Generation and thus can still hold his own and shouldn't be underestimated. He's another Pokemon who I really liked as a kid because, hey, he was a "dinosaur", but as an adult I don't really feel him as much.
I guess since Game Freak went with the "lamer" prehistoric creatures for the other Fossil Pokemon, they needed to throw folks a bone and give them at least one "dinosaur" Pokemon. I'm not sure if Game Freak knew that pterosaurs weren't actually dinosaurs, but regardless they're thought of as dinosaurs by the general population, even today, that I can't blame them for just going with that idea. And I'm not just assuming that they designed Aerodactyl as a dinosaur, because its original PokeDex in Japanese Red and Green even states that it was revived from a "dinosaur's genetic matter". But that is a weird way to phrase that, because calling it a dinosaur's genetic matter makes it seem like the original creauture was not actually a Pokemon until it was revived? Or, at least that's the way the sentence seems to be saying when I read it. But you know, with all the popular dinosaurs featured in Jurassic Park they could've chosen, I'm surprised they went with the pterosaur. They're certainly well-known, but I'd say the tyrannosaurus, the triceratops, the stegosaurus, and the brachiosaurus are easily more popular overall, and probably what I would've had gone with first when creating the premier Fossil Pokemon. Furthermore, it seems Aerodactyl was inspired by Jurassic Park due to its revival method, yet pterosaurs were completely absent from the franchise till the sequel released after the debut of Pokemon in Japan, so thus it's kind of an odd choice thinking it over. But as a Pokemon, it's easily the most iconic Fossil Pokemon, so it all worked out.
Aerodactyl is of course inspired by pterosaurs, ancient flying reptiles, and specifically seems to borrow the main traits of the rhamphorhynchus genus such as the (semi) diamond-shaped tail, curved beak, and sharp fangs. Real-life pterosaurs were predatory creatures, but mainly preyed on smaller animals such as fish and such, whereas Aerodactyl appears to be an apex predator capable of taking down larger foes. What killed the dinosaurs? The ice age! Or, possibly Aerodactyl, since it seems like it could probably take on any normal dinosaur with all of its Pokemon powers in play. Nowadays, Aerodactyl barely resembles how pterosaurs are believed to have looked by scientist, but even back in the 90s when Jurassic Park influenced the common view of dinosaurs in the minds of basically everyone not versed in prehistoric biology, it's obvious Game Freak took a lot of liberties with the design. If anything, Aerodactly is basically a dragon, and has often been seen as a "pseudo-Dragon" alongside Charizard and Gyrados. I imagine perhaps Game Freak may have considered making it a Dragon at one point, but like the previous two making a Dragon who was strong against Ice-type Pokemon just wouldn't be fair. That said its nature as a dragon is less pronounced than Charizard and Gyrados, as it doesn't learn too many Dragon-type moves and isn't part of the Dragon Egg Group---still though, it's been a steady member of Lance's team throughout the series leaving the dragon impression in the minds of virtually every player who faced one during their Elite Four challenge.
By the way, there's actually a real-life pterosaur named after Aerodactyl! A species once thought to be simply a member of the Pterodactylus genus was spun off into its own, single-species genus known as Aerodactylus scolopacipeps, who was explained to have been named after Aerodactly due to it being a very suitable name---it basically translates to "wing finger". The real-life animal doesn't really resemble Aerodactyl, but like Aerodactyl it has elements of multiple species of pterosaur giving it a uniqueness akin to the fantasy creature. Pretty cool, and goes to show you how popular and influential Pokemon has become.
Of course Aerodactyl played a major part in the anime, involved in one of the most important moments of the series the debut of Ash's Charizard who evolved to rescue Ash from the Fossil Pokemon's clutches. Aerodactyl is the most prolific Fossil Pokemon, and has a few other starring roles such as a more sympathetic focus episode in the Chronicles series where Gary befriends a revived one, and a later Diamond and Pearl episode where once again one pulls a Jurassic Park and begins rampaging around a city. Also in Movie 5, Aerodactyl was also revived in addition to Kabutops and terrorized the city of Alto Mare. It's actually not too many appearances considering the length of the show, but more than all the other Fossil Pokemon got.
#M142 - Mega Aerodactyl
Rock/Flying
Another missed opportunity as far as most fans are concerned to make a classic pseudo-Dragon into a full Dragon through Mega Evolution, like Mega Gyrados Game Freak kind of let folks down. Also, it's another Mega Evolution I've seen a lot of dislike for for taking a classic and streamlined design and adding a bunch of additional bits and pieces that don't really fit together in a cohesive way, and just make Mega Aerodactyl look kind of weird. But Mega Aerodactyl increases Aerodactyl's Attack and Speed greatly, making it a more potent sweeper, while also bumping up its rather weak defenses a bit more to make it less fragile, although really the goal of Mega Aerodactyl is probably to cut right through the enemy before it can be hit at all. It also gains the Ability Tough Claws, powering up its direct-contact moves that fit its role as a powerful hunter by 30%. I think most fans who use it for making Aerodactyl better again might still wish it looked a bit better.
Anyway, Mega Aerodactyl's actually kind of a weird Mega Pokemon when it comes to both the lore behind Mega Evolution and Fossil Pokemon. How Mega Evolution came into being is still a mystery, but generally the idea pushed forward by the flashback in XY suggests it's possibly the result of Pokemon involved in the Kalos War---so why does an Ancient Pokemon revived after years of no human contact have a Mega Evolution? It seems like all the other Mega Stones came about due to ancient bonds between humans and Pokemon, but then Aerodactyl suggests it may be a natural thing since that bond didn't exist till just a few years ago. Of course it seems even Game Freak themselves haven't really figured out the exact reason behind Mega Evolution, so I may be wrong in that assumption. That or there really were ancient trainers back in the dinosaur days. Another interesting bit of lore about Mega Aerodactyl of dubious canon is that the official Pokemon XY website claims that some researchers in the Pokemon World believe Mega Aerodactyl is actually what Aerodactyl looked like pre-revival, and like in Jurassic Park the regular Aerodactyl isn't a perfect copy, but rather a simulacrum created through substituting the missing pieces of its DNA. I don't think this ever was mentioned in the actual games, but if true, it makes us reconsider the notion that the Rock-type was a result of the revival process, as Aerodactyl was thus always part-Rock, and beyond that, it was even MORE of a Rock-type in appearance in reality.
Mega Aerodactyl has only cameo'd in the opening of the Mega Evolution Act I special so far in the show.
