Yo, I tamed a rex by hopping on a tall rock, shooting it up with tranq arrows and feeding it regular meat

KOing one and taming isn’t a problem it’s just most of the time where ever you knock out a Rex there will most likely be other predators around that can kill it while unconscious, I would clear out the area or lure it into a different spot if you can see other animals that might interfere with taming.

To tame a Rex build a stone trap by placing foundations in a square or rectangle at least 8 by 8 then making 4 walls out of stone door frames 4 high (or you can use standard Dino gate frames for 3 walls, then put the door frames for the 4th wall). Then make a wooden ramp down one side of the trap (the ramp will attach to the top of the door frames). Once you have your little trap with a ramp get the Rex to chase you. Run up the ramp and make sure it’s right behind you, then jump into the trap and run out one of the door frames. The Rex will fall in and not be able to leave. Tranq it out through the open stone door frames or Dino gates from a safe distance away. Catch any level Dino with this trap. Bigger Dino’s need bigger traps.

I have 2 rexs named stomp and chomp and used jerky and it tamed really fast

if you’re staying on old ark mobile instead of the new one , make sure you don’t leave it when you’re taming , they keep dissapearing mid tame on me if i don’t stand and watch

I tame one at lvl 50 and it was lvl 80…….

Took me three hours to tame

If you can’t get the most recommended tame for each boss, this is one of your next options. Also pair with a yuty, and if in a snow boss arena, use a otter. Happy Rex hunting!

Tame one they said it'll be easy they said tries to take

what I hate you guys

Rexes have a very deep wade depth. It’s up to their back

For some strange reason the pachyrhinosaurus puff has no effect on it when Koed

on mobile i shot one with about 10tranqs before running out, then i had to use a slingshot, which broke multiple times until i couldn't repair it, then i jumped down n used a club which broke n i couldn't repair it either so i finally punched it unconcious before stuffing some prime meat into it right before my ipad (and i) died when i had battery again, i died again (luckily i had a bed next to there) then i ran over and luckily it was tamed, then my battery died again.

I had a level 8 Rex and it took 18 arrows to take it down and it only needed 2 narcotics it takes a while to take but the trex is worth the struggle.

You can pretty easily kill any lvl of t-rex just by stegosaurus, when riding it because stego got knockback that high that he is not gonna give rex any chance to hit.

Okay so people are saying to use platform saddles which yes is not bad it’s just work to get a quetzal, if you have 2 people all you have to do is build 3 stone Dino gates in an unfinished square away from the Rex, then get the Rex to aggro on you and lead it in and go through the middle square (you can use large bear traps but I never use them) and then while the Rex is still aggro at you the second person needs to come behind and place the last gate.

To roar on mobile swipe up then down or just swipe down :)

If you see it when you spawn leg it

The boxing method mentioned by others is very useful! I trapped a level 92 Rex in the box and it took under 20 tranq darts with the basic longneck rifle to knock it out (most were body shots before I started aiming for the head, I’m not sure if headshots increase torpor quicker). I killed some baby dinos beforehand and had my hyeanadon hold the prime meat in the craftable meat punch saddle. The tame bar goes up by over 20 percent for prime meat each time it eats, and 9 percent if it eats raw meat. The guide says the Rex’s TORPOR reduces quickly, but it DOES NOT. I did not need to put any narcotics into the Rex throughout the entire taming process. Have fun, you got this!

I got one yesterday they are amazing they are slow but really strong high damage good health and are a really good option for boss fights hardest part of taming them is finding them since they are rare and spawn on mountains the redwoods and the snow biome on the island map pls like this or a Rex will spawn at your base

Big boy like meat big and strong

Very easy to knock out because they are slower than a lvl 1 character so every so often turn around to shoot it until it starts to run
