To tame this bad boy is very easy, i will tell you the most easiest way to tame more then one if you want!

1 build a raft

2 build a cage on the raft that is made of stone. Build 6 rock foundations in the front of the raft then build 3 stone roofs for the floor, because this part will hang over the raft then build the three front walls on the on the raft with stone door frames, do not build on the side you drive the raft leave that only 2 door frames high! Then build the ramp to from the low back part then you have completed your portable Trex trap!

3 look for a Rex on the beach or close by

4 then lead the rex in your trap

5 tang it and tame it!

The reason you build the portable trap is you can take it back to base and tame it there so that way you have all your resources in one place to tame it good luck!

Make sure to kill any creatures it aggroed, and do not leave it by itself, I was taming one and an argie in the redwoods so I left it to check on the argie, and when I came back it was getting killed by a Dino it aggroed. To see the full depressing story look under Barryonx, newest, utility, and Argentavis, newest funny.

A tribe mate and myself brought hundreds of arrows due to the X-dino increase to damage resistance. Turns out after doing some research that they dont need 3x the amount of arrows they just take longer for the torpidity to raise high enough. I would recommend bringing a spy glass when taming X-Dinos.

Throw your EX at it and run believe me works everytime

Thumb wrestle the rex for max taming efficiency. But if you dont win the rex will taunt you in front of your other dino. And its pretty embarassing.

When your taming your first Rex I would suggest to trap it with STONE gates And also feed it prime meat

It wont aggress you when you are riding a mount

Their not that hard trust me don't get scared by them as soon as you get long neck rifle and tranq darts your ready to go. I waited way too long and didn't get my first rex until level 80 just get an argie fly up to a medium height rock and start spamming tranqs into his head. Need about 20-30 tranqs for a low level rex

It’s really easy to kill a Rex as long as you have a flyer

It a level 90 guy with 10 narc arrows by crossbow to knock out a level 26 Rex female...still waiting to tame

For those who don't know if you cryopod a Dino its inventory will disappear saddles won't but skins will hope this helps😀😀

Believe it or not, it’s believed that the T-Rex 🦖 was covered in feathers, but not entirely like what we believe of on a raptor(Utahraptor, Velociraptor, Deinonychus, etc).

How to tame:

1 Get a longneck/crossbow I recommend ascendant longneck/crossbow

2 Make a trap for easier taming

3 get shooting balm if on mobile

4 trap the rex

5 knock it out

6 feed the thick boi

And boom you got a rex

If you see one try let other wild creatures weaken it ,if not only attack if required. DO NOT ATTACK IN EARLY GAME WHEN U ARE JUST STARTING A NEW WORLD

they dont agro on scorpions and pterodactyl thingy from what i know

I see two of these bad boys male and female at my base trying to break in

-2 minutes later-

I HAVE DA POWA

These things are way easier to tame than i’ve heard just grab a bunch of tranq arrows (50 to be safe), taming food and head off to a mountain. They always spawn around there, and if you can get high up on a steep slope they won’t be able to get you and you can just tranq the hell out of it.

Build a Stone Pilla trap what didn't work then when the Rex is chasing you hide and wait the the Rex attack the trap. When he doing it SHOOT HIM WITH ALL YOUR TRANQ ARROWS. (sorry for bad English)

I tamed a lvl 150 with 50 tram arrows

Can be carried by the Rynio. (Dragonfly)
