The usual starting flier. Their spin attack can easily clean out swarms of meganeura and titanomyrma. You can also use it and other fliers to lure away imminent dangers you're not prepared to take on from your home by aggroing it and flying away. Later on switch to argy since it can travel longer and carry a wider variety of animals.
How to do barrel roll on mobile: Go to settings and then go to controls then either go to left multi tap or right multi tap. Then select Reload/Alt attack2. When you are done, go and press on your screen twice on either left or ritght side. And you pteranodon can now do a barrel roll! Disclaimer:wastes stamina alot so be careful. Like so newbies see this!
My Pteranodon, Shan. Absolute legend. True trooper. Top dog. Killed level 139 Spino on his own. Only level 92. Killed 20 Therizinos. 5 Carnos, 19 Direbears. 31 Raptors, 2 griffins and one Argentavis including a Megalodon that poked its tail up. Can fly from East to west without landing for stamina once. Wiped out a whole crew of boas with 5 barrel rolls. Rescued my Dilophosaurs more than twice. Very useful Pteranodon.
These guys are extremely underated in combat.Just make dodo kibble(mobile) or feed them prime meat. Pick high levels one and breed them. I have my terrorist level 460 Pteranodon Imprinted 100%(I'm playing on hard mode mobile).If you do the flip thing it will deal 1K2 damage and you could take on any dino on Ark since the Attack is so fast as it move so you will never take any damage when played right.
Combine that with the spyglass bug on mobile will have you unbeatable. Just do the barrel roll attack and use spyglass in the middle of that. The damage could be multiply by 20+ times if you got a really good snap point to roll. Just abuse it and kill like 4 títan and Giga every time they spawned then you will find yourself +40 levels in just a week
