The safest way to trap a rex is to build a 2x2 square STONE foundation, add 4 STONE door frames on each side, and add four ramps to make one big ramp on the side your going to lure the rex into. Then, just have it chase you into the taming pen you've made, and get yourself out through one of the door ways. The next safest, but a little bit more risky and resource friendly, would be to set up 2 STONE dinosaur gate ways to make an angle, with a LARGE bear trap in the middle, so that once you lure the t rex into the LARGE bear trap, you can place the last dinosaur gate way behind it so it won't get out. Then, use a nock out method of your choice. Once it's nocked out, put your taming food of choice in it's inventory, and wait for it to tame up. No creature of my knowledge attacks an awake or unconscious rex, so you can go far away from it for a while if your in an area with other Rexes.

The rex is not especially hard to tame. There is several options in how to do it.

1 stand on a cliff that is higher then the rex an shoot it with tranqs of choice. It will start running when the torpor get high.

2. Use a thyla or wolf or equus or any other fast tame that you can use weapons when riding. Shoot the rex with some tranqs of choice and run away a bit. Shoot again the run away. Repeat untill the rex start to run away and then run after the rex and shoot till ita a sleep.

3. Use a Griffin and fly above it and shoot with tranqs. Fly after and shoot with tranqs till its asleep.

4. Have a tribe pick you up with an argy and fly above the rex and shoot tranqs and then fly after when it starts to run.

Hope it was helpful to someone 😊

Very easy, get 4 stone dino gates, place 3 down (a square with a opening) put a bear trap in the middle of it and then lure the rex into, when the bear trap triggers place the last gate in the opening behind the rex, then shoot at will. This works with many different big creatures

Here is an easy way to tame a rex. Step 1: find a rex either far away from danger or alone. Eliminate the danger if there is any.

Step 2: Build a 9-10 high stone pillar with ladders to get up (do this a decent distance from the rex.

Step 3: Climb the pillar and pelt the rex with tranqs. When it starts the run, climb down and continue to fire at it.

Step 4: Put food and narcotics in its inventory. Enjoy your rex!

Rexs are really easy to tame I knocked out a 130 but it disappeared when I came back from getting food for it and I was on single player and out of render range so I have no idea what happen then I found I level 100 which wasn’t great but it was ok ok the first one I just stood in a hill and shot it with a cross bow the second one I tried to trap it but I didn’t think it would break wood Dino gates so easily so I ended up just running around after it I have a bit of a issue about the info on the rex it says torpor drain is high but it’s really not you don’t need narcotics unless your using regular raw meat but you won’t need a lot as I said they are really easy to tame as soon as you can get tranqs you can tame them even with a bow but I wouldn’t recommend it I think the saddle is a bit to high level considering how easy they are to tame just don’t get to close they bite

On MOBILE-

Tame whatever level Male you want, and tame whatever female you want, using dyed crushing amber, color one of them red and the other white. Breed them, get about 5 eggs, the babies should have red and white in them, and boom, you have rexes that look like alpha rexes.
