Its very easy even low level like level 10 (if low level pteranodon) if hes low level and u dont wanna waist ur tranq arrows then... 1. Find a pteranodon
2.stay at the spot that the pteranodon is hovering above. 3. Bola him when hes on the floor. 4. (If hes low level) hit him with a club. 5. If u really wanna give him the best stuff and his favorite food then ok but raw meat will do just fine. Some name ideas: air pteranodon, pteranodon airlines, economy class (quetzal bussines class and wyvern 1st class)
When knocking pteranodons out, be sure to have a bola, it doesn't take many tranq arrows to knock it out. Once it is down, put spike walls up around it (with a little space so you can go in and out) so it doesn't lose taming efficiency or die.
To kill pretty much anything on these birds, tame a high level, then pump stam to 3k, then the remainder in melee. Barrel roll into alphas etc. But keep eye on Stam. Never regen Stan on ground, know your ledges!
