After u got an argie and a high lvl ptera its a rly easy tame. U just fly to the mountains and get one with the desired lvl (spyglass for the win) with an argie. Sometimes it attacks ur argie while your picking it up (if thats the case just drop it and pick it up untill it doesnt hit u). When youre at your base a tribem8 can tranq it while its in your claws or u can build a 1x1 and drop it in there. Then u can just get prime meat with a ptera or however u do it.
Easily knocked out when you use a bloa. When stuck shoot in head while you can and itll go down quickly. Tranq darts make the process quicker, but arrows will do the job just fine. They can be picked up and dropped into safe taming cages by argies to make this easy tame all the more easy.
