Utility Roles for Pteranodon:

First Flyer. The skies of Ark aren't as deadly as the ocean, but anything that flies offers a quick way to traverse areas that may kill you. Trust me, I've skipped an entire section of swampland with this thing. Plus, fliers offer a quick getaway from anything you think you can't take on. Just be sure not to land near a pack of Raptors. (level Stamina and Weight)

Alpha Slayer. Alphas have a really hard time touching aerial creatures, but Pteras are by far the best choice because they are the most nimble. Get at least five of them with a mate boost and you can pretty swiftly deal with alphas. (level Health, Melee Damage, and a little Stamina)

Scout/ Backup Flier. Pteras are small, nimble, and fairly strong. If you are on an Argy and you die, simply hop on the back of your Ptera to retrieve your Argy! (be sure to fly back with the Argy, it's slower than the Pteranodon) (level Weight, Stamina)
