Be careful when attempting to approach a Yutyrannus as it may have Carnos with it (That are probably damaged buffed), if you have a quetz (or anything that can pick up Carnos), attempt to grab the carnos to draw them away from the Yuty (Or kill them outright, although the Yuty may take damage), making it less dangerous. At this point, when the carnos are gone, build and lead the Yuty into the trap WITHOUT A DINO. If you bring a dino with you at this point, it will likely be scared from the roars, screwing you over. After the Yuty is detained, it's a simple wailing of torpor till the big fluffy dinos gives up the ghost, which is when you feed it to have a cute, deadly, strength inducing badass that is the Yutyrannus!

These thing aren’t particularly hard to tame, but there not super easy either; if you ride a small, fast mount it’ll fear roar it and kill it. For a trap you should build a 2by2 stone build with Ramps, but you could build a 3x3 to be safe. Their fast but not to fast, so I recommend trying to get as close as possible to your trap when trying to get to aggro on you into the trap, so you can get in the trap before it hits you to much, then just traq it till it knocks out and give it some prime. You can get prime in the arctic by killing mammoth or carnos.

Quite a difficult as it is fast so when running is hard to shoot at with crossbow and tranqs however with a trap or a good hill point and a fast tame of your own its is only about a 10 minute mission. Also i like to tame carnos as they can be annoying to kill and easy to tame and even in the wild they are a good combo

When I was taming mine, it fell into a gorge. After that I just shot it from the top of the gorge, when it ran I got on my bird and flew to the bottom of the gorge and shot it. It later fell to the ground where I fed it meat and tamed him. I named him Copper, and he’s very useful, and I recommend him for boss fights

Build a trap out of 4x3 stone foundations and 2 stone doors high, then build a ramp on one side so that it can walk into the trap and can’t get out. Then kite one over the trap so it walks into it using a wyvern as they don’t get affected by the fear roar. Spinos also work because they can walk over the two wall high walls.

These are one of my favorite tames but they are quite difficult to get. DO NOT USE A FLYER. They will panic and you will not be able to control them. Which can get you killed. I recommend using a rex with very high health to lure it away from any other predators but make sure it’s on passive so it doesn’t kill the yuty. Dismount while it’s aggro on rex and use best gun as possible with tranq darts. Keep an eye on the Rex’s health though. (I recommend several people and a backup rex) -a really cool person

I will never go back to tedious taming traps again now that the net exists! It took me about 5 nets using SHOCK darts to knock out a level 140, and the nets have about 10 seconds before they can be used on the same dino again. Net it, tranq it, get back on your flier, wait, and land to repeat the process again. I did this by myself with little trouble other than getting the yuty to not run into water.

Also watch it when yiu think you're about to KO it. It can be hard to tell at first glance whether it is simply trapped in the net or fully knocked out.

To trap all you need is 3 stone Dubble door frames 1 foundation and 2 ramps

put the foundation down

2 frames stacked on the front

1 frame on the back

2 ramps connected to the 1 frame on the back

Hit yuty make it run it the trap from the ramps

Kill the carnos

Knock out tame it and boom yuty
