If you have a tapejara tamed with good weight around 800-1000 and decent stamina anything above 1000; then taming a T-Rex is super easy. Just choose a designated flyer and have 2 friends shoot at the T-Rex from above.

This is how I kill a rex

Me:sees rex*

Rex:sees me*

Rex:charges at me*

Me:pulls out ascendant sword*

Game:Me Killed lvl 258 Rex.

Game:rex leaves game

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

If you are going to go hunting with it, it’s best to just wait until you are on the right level and get enough materials to make a saddle and ride it. If you can’t wait till then, definitely don’t hunt near water or the ocean at least. On my first day of my first Rex, I got carried away, got on my Carno, and started to attack a Brontosaurus. It retreated into the ocean and my Rex chased after it, then a surprisingly big swarm of Megs attacked my Rex and I couldn’t save without getting out alive. It managed to kill a few Megs, but it wasn’t a match for all of them. My point is, if you want your Rex to live, think before you are about to do something with it.

I got Rex arms yesterday because i saw two brontos vs one Rex

Guess who won

Best way I've found is tranq arrows + crossbow + Griffin and hover just high enough to where it can't get you and be in a place without alot of other creatures. It'll stay below you and you can shoot "through" the Griffin down at it until it starts to run. Then just switch between flying and shooting.

If you do encounter a Rex I would put on your best armor and take out some good weapons if you have at least maybe Bary you should be fine just my idea hope you like it

Is you have the materials to make a large bear trap, taming pen, and longneck rifle with darts just lure it with a flyer and use prime meat or kibble for an effective tame i got a level 50 today on the mountain. I hope you found this helpfulGood luck!
