When taming a pteranodon you need narcotics, if you don’t it’s gonna leave half way, I also recommend making dodo kibble since it’s usually easy to make and it’s the easiest way to tame them. Also if you don’t have that use prime meat, but if you don’t have that use the regular meat, since there torpor is low I recommend feeding them narco berries or narcotics so then you can take them fully without them flying away. If you need to tame them, bola them, then tranq, or slingshot, or hit them to knock it out, then you put everything in.
