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.
This Smaller T. rex furry is able to Spam roars which either buff its allies attack power by 25 percent oooor or scares enemy/wild Dino's away the bigger the Dino the more scare roars it will take to make it feared making a Dino feared will make it walk the opposite way of you and unable to do anything else for round 20 or 30 seconds They also look like a really good pillow besides dodos pretty much a dodo and a Rex fucked and this epic shit came out
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.
