How to tame a pteranodon:

1. Grab some bolas

2. After finding a pteranodon, throw a bola at it

3. You can shoot at it with a tranquilizing ammo like tranq arrows or certain darts. Or use clubs and slingshots.

4. After it's knocked out, you can feed it meat. But I highly recommend feeding it dodo kibble as it's easy to make and speeds up the taming process.

5. I always forget to mention this, but you might need some narcotics.

Hope this helped!
