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.
Taming this big fluffy T-rex won't be easy when having or riding a dino with you because of its fear roar. It's hard to tame it because it will scare your dino away. So try to get it off a cliff but a cliff where you can see it and shoot it with tranq arrows. But be careful because it can go in the water. Once knocked out give it raw meat or mutton.
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.
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.
