How to Tame a Pteranodon:

1. Get a wooden club, about 3 bolas, some meat and maybe even some narcoberries (if they are the black ones)

2. Find a grounded Pteranodon and bola it.

3. Knock it out with the wooden club.

4. Feed it and if needed whack it with the club a few more times to keep it unconscious. Remember to keep an eye on it's health. Guard it as well from any creatures which may attack.

After a few minutes you should hopefully have a Pteranodon! I hope this was helpful!
