In Old Ark Mobile, to tame a ptera fast is by completing the "Hunt Dilophosaur" pursuit. When you get the ascended bow, make atleast 10 of tranq arrows. After that, complete the "Hunt Megapiranha" pursuit to get Soothing Balm, which is useful to make taming 10 times faster. After that, you want to search for a high level pt, (atleast above 100 lvl) and shoot it unconcious. Use the balm and kill some Stego or dinos that gives you Prime meat when harvested. Place the meat in your ptera, and it will be tamed!

This process took about 10 minutes, and it took about 3-5 minutes on a 250 lvl ptera (because i have tamed it)

The pteranodon utility is just it's speed, which if you ask me, i will rank it A tier for that because you can fly faster than most of the creatures! You can also get from herbivore island to carno island very fast! (Very fast if tou tame a very high level one, atleast above 250)

It could also pick up small creatures and players! Making it one of the greatest early PVP flyer.
