One of the worst tames you can make.As much as you upgrade it's stamina it won't take long to run out. And when it does it just lands whenever it cans. Hostile or not. Today my useless pteranodon with 63 levels on him landed to rest on a mountain full of Argies and Savertooths. And by the time I tried to run from them. He didn't regenerate until a puck of Raptors joined the club. So.. no not worth the metal of the saddle OR the taming. Waste of time. It's only advantage is that flies. For small time.
