One thing which I like to use is a good flier, because once the yutys, start torpor running they cover quite a bit of ground pretty quick and the flier will help keep up, or a fast ground mount, it would also be helpful to ride a mount that allows yuh ou to shoot while riding.

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

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.

Easy tame method:Make 2 by 2 trap stone with doorframe as walls and 4 ramps on one side then take a wyvern and run in front of yuty he/she will follow you then lead them to trap

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.

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

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

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!

When taming on Scorched, it’s good idea to use the Lymantria gas to slow it down while your partner can run after it and tranq it, if you don’t want to use traps. Works with other dinos too 🙌🏻

The best way is with a Wyvern and a few darts
