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!

Got a Rex saddle at level 50 I am mobile player and tamed on Rex from the Griffin mountain easy peasy

Controls on switch!

R2: bite

L2: roar

I'm saying this NOW AND NOW ONLY, the following is the same for all Tek saddles

R1: toggle shoot mode

R2 in shoot mode: fire!

Last: trike

Next: megalania

Rexes Can’t break stone, with this in mind you can actually lure one into a trap, preferably 6 by 6 foundations and 4 walls high with a doorframe foundation if you’re going on foot, which you can easily do because rexes are actually reaaaally slow

Use shock darts for the x-rexes, anything else will take years.

Found a level 395 rex on lost island at the grassland areas below the volcanoes. It was a natural spawn and I was able to tame it successfully (on a single player). Seems to be a glitch- but apparently people have seen levels up to 800.

Hope you found this helpful

Found a alpha Rex with 3 Rex’s and a alpha carno at my base when I logged on. I now have no base left

You don’t need a trap just get to a mountain and shoot it it’s easy I tamed one doing this it’s really easy

One of the best and most efficient ways to tame one is use a large wood signpost or a metal signpost literally one of the best traps I've used get it to by a decent tame that has good health and try to place a bunch of these in front and around it to trap it and back away and it will just sit there and bam rex tamed

In 2018 it still works the same as in 2015. Stand on a rock, and shoot it. Then, just breed the tamed ones.

If you want one look in the mountains or snow and once tamed put it in a cry pod and take it back to bace

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

what I hate you guys

DONT LISTEN TO THE PEOPLE WHO SAY NOTHING WILL ATTACK IT!!!!!!! Mine died because a murder turkey attacked it right as it was finished taming that is an hour I will never get back thanks a holes

Easy:

make sure you have a getaway, a couple stacks of meat, and a ton of tranq arrows(or darts)

stand on a real tall rock

shoot it to make it come to you (with rifle or crossbow)

once it’s stuck at the bottom of cliff (or rock) shoot it with TRANQ ARROWS(or darts)

repeat until it goes unconscious

get off and place your meat in inv

wait half an hour and you got the most popular apex predator in the dino kingdom

Baby rex’s are so cute. if your breed them have a lot of campfires and wood or thatch. my Rex wants walk every time for the imprinting thing. Already so big soon she’ll be as big as her mother and father.

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

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