About the person saying that his/her max lvl pteranodon and a dimorph couldn't hit each other, i feel his/her pain, i did it once but with a pteranodon and argentavis was high in the air... So i killed carbonemys and insects to create another ptera saddle, once i created it i put it on Ptera (Petrie's wife) and flew sky high and there they were. We flew more than 45 seconds to see my Argentavis and Pteranodon. So after that i just flew by dimorphs.
