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.

To ko one you need a bow or cross bow with narcotic arrows. Then you need to find one. Once you do that you find a rock that it cant get up onto to and hit it with a normal arrow. Once it comes at you, you need to shoot it with the narcotic arrows the put your choice of for in it the there you go.

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

Fly on quetz with platform saddle,get it agro on u fly up , shoot with train darts the whistle quetz to target it cuz quetz slow continuously shoot the yuty till knocked out

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.

X creatures take 3x the tranqs required to tame a normal one.

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

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
