These thing are probably the best prime meat gatherers you will ever have I killed bronto it had like 18 stacks of it

If your on easy they only take a few 15 tranqs you can easily outrun them. Once tamed their only downside is their stamina

I would recommend trapping it with stone and a 50 should take about 45 tranq darts or 50just to be sure

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

Use a griffin that has a lot of stam and just run around or away from it

Don't tame until you want to breed them and make more powerful rex

I have three of these guys and they are extremely powerful. Definitely recommend getting some.

If u just finna kill some bobs you don't need a saddle just jump on top of it (from a rock) and whistle it into battle

Rex are easy tame as long as you are faster then it you can lead it in circles

If you want to take a rex all you need is a tanky Dino then let the red attack the Dino and shoot the red whilst it’s attacking

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.

Use toxics arrows it’s better for tanning don’t be scared of it

Not that hard of a tame I took my argi and 100 narcotics 50 tranq arrows and I set out to find one. While scanning the rivers I found one trying to get a theri witch was on a steep hill. I noticed the opportunity and I landed on the hill the rec could not get me so I used my cross bow and it took only 35 tranq arrows in the head to knock it out you know when it's about to be knacked out because it will start to run away from you so you can stay put and shoot it or you could follow it since it's running away it will not attake you. Keep in mind mine was a level 25 so a lower level would be easier to take. Like to share.

Imagine a x-tek-T-rex so cool right?!

No trap required. Get a fast mount that you can shoot from while riding it, like a raptor or baryonyx, tranq it while kiting, let it flee to a safe area before dropping it, then secure the area. Starve taming works best.

YOU CAN TRANSPORT A BABY REX WITH ARGI

Rex is slow so don't waste hours making a trap. Land shoot with darts and fly a little farther. Then just get prime meat unless you can't stand 5 minute difference between prime and kibble

I don't know why people say ad foundations or something I do it with just a crossbow with trauqs and shoot of a tall rock or near by cliff but I suggest the cliff because it could climb up the rock and kill the heck out of you and also I littery have 4 of this bios!

Found a max level tek Rex on mister island but there is a lot of carno's but Rex spawn slot in monsterisland

75 lat 75 long spawnpoint on SE. Although I had trouble taming there because of lack of good rocks to hide on as they can climb most of them, also because my argentavis killed the only rex I could make unconscious as it was trying to hit a pulmonoscorpious..
