If u lure it in a trap with a pt ir something than bola it and dont feed for 10 min then u can insta tame it u dont have to wait much time
Tropeognathus
The Tropeognathus is a rideable flying pterosaur. While they are not the fastest flyers, they have excellent stamina and are great for transportation. Its beak allows surviors to "recycle" items and gear to their base components.

How ARK players tame and knock out the Tropeognathus: what to feed it, what to knock it out with, and how to keep it safe.
When you Bola it hit it a few times with a longneck or something it will take food to regenerate so yoz can tame it faster
For the people who Don't know you can bola it.
Make a trap like argentavis and a balistic and build it in front off it Then bring him to the trap and that is it Extinction is the best place for this
