Last time I tamed me one seemed the Yuty yell did not effect my Quetz in any way.

It's over Anakin, I have the high ground!
You underestimate my power.
Don't try it...
Yutyrannus screaming

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.

You're pretty much always going to need a trap for the higher level ones; they will run a million miles when they realize they're getting knocked out!

How to tame yutyrannus: run in the opposite direction and use a bola on your friend

At lvl 140, it took 50 minutes to starve tame with 25 mutton at taming effectiveness 97.3% (+68lvl).
About 30 tranquil darts with a 210% longneck rifle and 10 trans arrows with a 241% cross bow.

2020 update the do not drown under water thumbs up!!!

While taming, yutys do not drown if they are knocked out in the water! <3

All you need to do is just get the high ground

What you have to do is bring 4 metal billboards and 3 large traps 🪤 next get the attention of the yuty by shooting with a tranq. Then run in the trap that you made and place the large traps quickly next once the yuty is stuck in the bear traps place a bear trap behind the yuty so it’s trapped. If carnos spawn here is how to deal with them make a stone tower or 2 stone pillars and a ladder 🪜 next idk if carnos go bye bye after you tranq out the yuty put if they don’t and you have to kill em bring a high lv dienocus (idk how to spell it) becuse its bite hit box is small unlike the gigas so it want hit the yuty and bam place the mutton in that bad Boi and u got yourself a yuty enjoy 😉
