Which dinos are aggressive towards wild t-rexes?
I'm willing to solo tame a third trex and have a few questions concerning the hostilities and neutrality that is present amongst some predators.

I've seen dozens of times Trexes being ganged by groups of pulmono, sabres, raptors and carnos altogether. Has someone any idea whether this occurs because the trexes aggro them all or not?

The thing is, I've tried to solo this rex last night and I failed miserably because a sabre jumped out of nowhere and might have killed it - though I'm not sure cause my other trex was nearby and its aoe could have done that too given the fact the tiger died instantly.

So, has anyone seen predators aggroing rexes on their own? I've noticed my tamed ones walk freely amongst raptors without being attacked, but I can't find any reference on the gamepedia.

The whole point is: in your experience are other predators a danger to your unconscious trex while you're off gathering prime, or will it just lay there undisturbed by anything that walks nearby?

I've also noticed alpha raptor don't aggro trexes, but I've seen so often groups of multiple species attacking a rex en masse and I can't figure out how that would have happened.

Nothing...unless the rex attacks it first or hits it with splash damage. The only beast I have yet to see a rex attack in the wild is a spino. What you have probably witnessed was a rex attacking one raptor and aggroing the pack, or accidentally hitting the raptor while biting another animal and aggroing the raptor/pack as well.

The rex hit them. Only three things will attack a Rex unprovoked: Spinos, Rex's and Players.

Everything else will ignore them unless attacked.


I guess it's possible Ants will attack a wild Rex, not sure.

Thanks, I am very glad to hear that.

The biggest concern when taming other stuff like say even a Carno is the risk of rexes spawning out of nowhere and eating your poor (almost) tamed dino. So, if taming a rex implies no dangers from other creatures - unless something else happens to fight nearby and deal aoe damage - I can feel assured I can make it.

Rexes do attack each other? I've never seen that. I'm also sure they often fight along, and so near to each other that if they could they would definitely damage one another - btw I still have to see a rex dying to another one. Usually they seem to team up.

Rex's will agro tamed Rex's, so I specified that since I'm unsure if they will also by extension attack a taming Rex in progress. Wild Rex's do hunt together instead of eachother.

no creature in the game will attack a wild t-rex if he didnt accidentally hit one of the same kind nearby.

I hope not, but for obvious reasons small predators scare me much more than rexes as they are very easy to miss when you are checking the area. Rexes are huge, thus easy to spot, and rarely. Anyway I noticed while taming a raptor that no other small carnivore aggroed it so technically until tamed it's treated as wild.

good, thank you for confirming the others' comments.

I learned the hard way, therizinosaurus seems to also attack Rexes, as well as anything that swims in the water, piranhas, sarcos. My T rex got killed by a therizinosaurus on my way home. So just a heads up, don't go near them if you tamed a rex far from a base, and are traveling it all the way back. I regret not just taking a saddle and riding it.

Holy crap how did you even find this post? it's from 2015 and theris and gigas weren't even in the game back then.
Holy necro batman

Lol that was some epic necroing.

But anyway, Gigas were added about that period.
