I just tamed a 135 by seperating the yuty from its carnos with an argentavis, yeh I got fear roared multiple times but after some time I placed 4 Dino frame gates with 2 doors on each end and had my friend run in and I close the door. Once trapped it was pretty straightforward tame just became cus things wil attack the yuty while it’s knocked out
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.
If you're trapped a Yuty recommended for you to just leave it for a few mins then knock it out. This way will be an instant taming that's because when you leave it until it's hungry as its moving too much in the trap as it tries to escape
