Get to somewhere high, like a mountain, then the tranq the Yuty until it starts running, once it runs the carnos will mostly likely run away as well due to their leader going bye-bye. Then it will run in circles attacking everything except for you. Then tranq it some more, but make sure to hit it. This is at least what happened when i tamed one solo.
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.
If you're trapped a Yuty recommended for you to just leave it for a few mins then knock it out. This way will be an instant taming that's because when you leave it until it's hungry as its moving too much in the trap as it tries to escape
