A lot of people say these are mainly early game fliers, but I do not agree. I bred and imprinted one and levelled up its hp and melee. Now it has 8K hp and does 1K damage per barrel roll. Found a lvl 100 giga but I wanted a better one, so I took out my pteranodon and barrel rolled into its tail repeatedly. After a few minutes it’s dead. It managed to bite me a grand total of 7 times while I hit it ~80 times. Since I had an ascendent saddle it only did ~3k damage (most of these came from bleed) with those 7 bites. Imo the pteranodon’s barrel makes it the strongest flying battle mount in the game by far.
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.
