These things are slow as heck, just run and shoot it and your good. Just make sure you do run into anything that will kill you or your Rex.

HOLY CRAP THEY'RE MAKING AN ARK ANIMATED SERIES SPREAD WORD SPREAD WORD I TRUST IN YOU ALL TO SPREAD WORD

Shoot them while they attack a diplo. They will stay distracted as the diplo plays with it without harming it!

I would think these were gonna be harder to tame but they’re actually not that hard, my stamina and movement speed is pretty high I’d say around 200 or higher but I didn’t need a trap or any of that, all I used was tranq arrows, u shoot it once then run away for a little bit turn around quick shoot it again then run away again and shoot it again and repeat, if it starts running it means it’s almost knocked out just chase after it and keep shooting and feed it meat!

How to raise and tame a good Rex

1. Use crossbow with tranq arrows or rifle with tranq darts

2. Find the Rex a tough opponent to defeat

3. While he or she is fighting, open fire on the king or queen

4. Once the Rex is down feed it prime meat alongside with normal meat in case you run out of prime

5. Use narcotics on higher levels bio toxin might be needed.

6. Once the Rex awakens take them hunting for large dinos and bosses too but they have to be extremely high level

7. When leveling up switch between health and dmg upgrades

Please take good care of your tyrannus. PEACE

Giga: has a weak jaws with teeth, which can only make the prey bleed.

WildCard: nope

They are actually really easy tames People are always like oh build a trap oh du du du du NO all you need it’s a Tanky parasur and some tranq arowws there then just wait 2 seconds before shooting again

If you use the bear trap strategy which is if you lead it into a Dino gateway that is shaped in a triangle and with a bear trap in the middle (Large Beartrap) and when it is stuck you must put a dinogate behind it to trap it and then knock out.

Place 1 stone foundation near the rex you want to tame, (not too close) then 1 doorframe and door, both stone. Then place 3 stone walls around it. Add an extra layer on top of the base structure of stone doorframes then cap it of with a ceiling. Shoot the rex to get it’s attention, then run inside and the rex won’t be able to hit you, but you’ll be able to shoot it. This trap also works for Spinosaurus and dire bears.

If you're using a taming pen for rexes, build it at least three walls high. Sure you are able to keep it inside the two walls high pen, but an especially cheeky rex might climb out of it, which is definitely not going to end well for you.
