So I tamed one of these guys and took him to the grand hills where there are lots of metal. To save the time of going back and forth from my base located at the western coast I tamed at least five pteranodons and leveled them up increasing their weight capacity. And I've been using them to transport metal,obsidian,crystals,etc that me and m anky collects. I used pteranodons to transport them by air which is a lot safer in my opinion. I've been playing ark for almost 2 weeks now btw.
Grab him with argentav or quetz, if u r not patience enough with their speed. (Dont be dumb like me who travelling from redwood to snow biome for obsidian with only riding this guy) damn.... Im so nub XD
