Really easy to tame just take some tranq darts and a tapejara and sit on the side of a cliff and tranq it

Honestly I’m the odd one out... I tamed one with a journey bow and a dire bear. No gates no platforms nothing. Just a bow a bear and patients. Hmph I’m weird

I have figured out a new way to tame dinosaurs cut off the dinosaurs meat wise in the area try and keep the dinosaur in the area and send a dodo bird out to attack the tea Rex with bunches of Botox in and it had the tea Rex eat the Botox and it’ll knock it out you go feed it meet make sure you have plenty of Botox in and you’ll have a pet your ex and no I would not recommend trying this whenever your level one side effects may be dead dodo bird hey might find you and run but seriously You better find a good hiding spot

If you are on an animal it's way easy to tame these guys. I'd also recommend having the kibble and having a creature of any kind with high health. You can knock these guys out on foot too, but it's a lot harder and you risk other animals killing you/the rex. I'd also recommend not going after any mate boosted rex, since the torpor you do is directly related to the damage you do.

All you need is a decent crossbow and some high ground with a good amount of Tranqs
