Go to areas between the swamps and redwood forests if you want to tame a pterandon. The swamps’ many predators (ex. Titanoboa) will provide a lot of prime meat and tranq arrows for you, and there are many pteranodons lounging around the area.

In short: Swamps are tranq arrow and prime meat farms (around 2 arrows can knock out a pterandon). Pterandons spawn a lot between the biomes. This is a mass taming farm.
