The Rex May look scary and can stun if you get to close. But it’s an easy tame if you shoot tranqs at it around other Dinos, especially herbivores

Easy tame all you need is a bed a raptor and a crossbow with 25 Trang arrows run While it’s chasing you and shoot with crossbow once nocked out wait 20 minuets then put your meat inside then go to sleep and you have a Rex

If you make a pen of dino gates with a behemoth gate on one end you can use an argy to pick up a smaller creature and fly just out reach of the rex to lure it, then drop the bait and close the door, no aggro till your ready

I’d say is wait in till it’s on low heath then start shooting it with truq arrows in till it is out then use the smoothing balm then you got a Rex

If you can get on top a cliff with a rex at the bottom, it won’t be able to reach you. Shoot tranq arrows/darts till it starts running from you, and then keep shooting while you chase it. Eventually it’ll pass out. Make sure you have a ton of prime meat and/or things nearby you can kill for prime meat....

I’ve tamed 3 rexes this way

3 to 4 stone dino gates in a square big enough to fit it inside and you good no bear trap or elaborate taming cages required. : l

Find a cliff or somewhere high where it can't reach you, then pump arrows or darts into it. To be extra careful have a flyer nearby to escape if it climbs up.

If you are riding the Rex and standing on higher ground than an alpha you can Time it just right so that as the wild alpha Rex is running up the hill you can munch his face and knock him back again. Killed many alpha rexes this way without taking any damage at all

When u tame a Rex, they will sometimes let out a roar before they attack what you targeted (if u have it set to “target”) the good thing about this is this roar will put small animals into a temporary stasis, like raptors, dilos, basically anything smaller then a ankleo or trike

Level up the speed so you can go faster than the dinosaur and there would be a time for the narcotics to make him sleep( this works for many dinosaurs)

If you find this big boi, just run

If Your a savage like me just make around 20 tranq arrows and make it chase you. Then you shoot it until it gets knocked out, but this method only works on a low level one

If you see one RUN and always carry a bola to bola any tribe mates or animals along the way

If you don’t want the long set up to tame, lead one like any creature to the bottom of a cliff, fly up or shoot it from the cliff and tranq it. When it starts the run, watch the cliff fall if you’re chasing on foot.

You can find Rex's near beaches and steep mountains

There’s a passive tame walk up to with meat

I go on cliffs and dart them from the top until it gets knocked out kill and large animals preventing it to die and put spikes around it and feed it all the meat you have on you.

Best way to knock out is to make a stone raft and put it slightly in the water so when it knocks it won’t drown. Has to be at least 2 walls high.

If you are feeling a bit lazy when you tame a Rex just lead the Rex to some high terrain like a cliff and fire away. But if you wanna do it the smart way build a trap with a bear trap and while the Rex is in the bear trap close the trap that you led the Rex into

You can usually lay between 1-4 large bear traps down in a line and stand just in front out of reach of them and shoot them with tranq arrows or darts.
