I just went in creative, used a ton of nacrotic arrows, and tamed it with meat.

Just tame a carbonemys with +5000 Hp and keep upgrade it till 8000 and craft tons of darts just to be sure.

It’s easily tamed just grapple a tree and tranq it over and over with a cross bow

You can run faster than a rex so all you need is a crossbow, some tranqs and determination

Find a overhang cliff where it can't reach then grapple onto it and hang, constantly shooting tranqs. Easy tame

Get a boat and crossbow and Peterson

Leed one to a cliff with a flying mount then tranq it with arrows, super easy because Rex can't climb steep cliffs.

Grapple on its back then tranq arrow the heck out of it, that is the best way in my opinion.

I would suggest to do the tame with a secon player. He should fly a argent and you should grapple onto the bird and shoot the rex from there. I got my 150 that way

If you already have a rex with a saddle and high health (mine has 20k) then you can simply walk up on your rex, get off so that you're still on it's back and then shoot the wild rex while your tame tanks the damage. I have tamed a few 150 Rex's this way. You can also use this method while kiting the wild rex, shooting it while it charges you and then move again.

STAND on a high place where Trex could not reach the shoot tranquiliser darts to bring him down

Use narcotics to make his hunger grow and the only give him plumonscorpius kibble

I tame mine on foot like a real survivor

If you encounter a wild Rex DON’T MOVE A MUSCLE!!! .if you do this it won’t see you as a threat.it will just stare into your sole.

Mame sure you have a good team of people switching on watching a baby rex grow. We had one of our guys just stay there with it for a while because we had college, he fell asleep for 10 mins and the rex starved because they're fat assess

By knocking out a Rex needs populated area you can get many people to notice it so when they come up to it to see what's inside You can wait with a long neck ruffle and shoot them when they open the rex

I just tamed a level 100 rex at level 15 with a slingshot

Had a bronto on passive mode with 4000+ health, then had the Rex attack it while I tranq’d it easy tame, low lvl tho

I though it was allo and i tamed it already when i was lv 46 (by accident)

Lure it to shore, grab it wjth a Tuso, and easily move to a better taming location. Plus, you can hold it in the air over the beach, and have your tribemates shoot it with tranqs. The tuso holding it will increase torpidity as well, and generally the rex won't attack while in the tuso's tentacles.

This might be a harder way but I’ve tamed two rexs so far with this method, one died though and as I was taking another it was eaten by sharks cuz it went in the water but I’m taking one right now. So the tip is to get in a griffin get out ur longneck and go ham on that baby. Griffins move left and right to do you can almaanis manouver around and keep hitting him. You never get touched and if the rex starts running away just use the birds speed
