We have tamed a mating pair today and best advice is to kill everything around it on and the carnos on a wyvern. The wyvern is not affected by the roar but everything else is. Argy will lose its shit and go nuts. They are also fast as lightening so ground taming is horrible. Definitely recommend kiting to a trap on a high health wyvern. Let it bite your booty-then in and up through behemoth gate. Land behind because it holds agro. Shut the gate and done.
It really is that simple though, they can't reach you or your flier on a big enough rock, so if you don't want to make a trap you can just shoot down from a rock or cliff once the carnos are dealt with. Be ready for a goose chase once it starts running.
