I use wyverns to tame these, as wyverns are not affected by the scare roar thing. Just find a place it can’t climb to get you, then just tranq it. Once it runs get on your wyvern and chase it, then corner it and knock him out. Not the most safe way but it works.

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.

The best way I have found to tame these guys is with 4 stone foundation walls. 2 stone wall high on each side.and one side have ramps. Kill all the car is with it. Shoot the Yuri from a distance and lure it up the ramp and in the cage. Done deal.

On the Valguero map, they are pretty much all in the snow biome. If you are on a dino, dismount and go knock it out yourself because your dino will get scared.
