They are more worse than T. rex since they could 2 shot you even if you have flak armor on if it's lvl 30 or above

They will slice your face

They may have toned their power down, but my 191 rex w/ 520% melee took down a lvl 40 Theriz after it attacked me in about 5-6 bites. Doing barely any damage to the rex or myself. (On an official server) the people that suffered severe loss fighting these maybe left out a lot of detail like if they were trying to tame it and letting it hit their dino. In a strictly combat situation, they don't seem to pose much of a threat.

If your planning on kidnapping this thing and taking it to the taming pen, forget it. We all know it isn't worth getting a quetzal half way killed for a evil herbivore... but your best bet is to bate it into a trap and knock it out while it can't move. They only do damage to wood and thatch but do only 1 damage on stone. So trap them with and stone pillers and a large bear trap to lock them down long enough to trap him with the stone pillars you have left after building a structure to bate him into.

Wish I knew these kill you while on your take just lost my argent because it killed me and I couldn't get back bast enough

STOP, DROP, AND REX

How can it come that the therizinosaurus can damage stone, while neither the spino or the rex can? Watch out for this guy in the wild, since he is aggressive to players.

You can't take Therizinosaurus lightly. They are able to damage stone structures and do huge amounts of damage. They are slower then Rexes, but they have more stamina, so they run longer.

I had a 260 lvl ptera with 450+ melee and 2100 hp. I saw one lvl 5 therizi. Had a fight, i killed it but it took half my ptera hp. Thats crazy really. A lvl 5 can also deal so much damage

This guy's ez if ur near a cliff or anything high just use a bow to agro it and just ez kill

Trying to take this dude when he woke up and just slapped me. Going to use more necrotics next time.

Back when I first I saw it, I had no clue what it was. So I named it Scarysaurus. Every time I saw one it killed me. now every time I see it I, let's just say, get my revenge.

Encountering one of these.... Let me check

The results are DEADLY

My level 1 nearly 2 triceratops killed one of these… lol

When you see this guy and you can't fly, you can spell Apple sauce with only "a"s : Aaaaaaa

Im amazed it quite littrealy killed 7lv 999 megapirratas(note:i have a glich what makes some radom creatures lv999) in seconds it was lv 8...

They ain't that frightening as they seem, just use a raft and a good wepon (I used mastercraft bow,stone arrow) to kill a lvl 55 one.just make sure they r not too close to the raft

By(TD)

… A lvl 105 just killed my miles (lvl 10 argen) so I murdered it with a gun.

If you see this you will probably die, herbivores with 9 inch claw apparently act just like a carnivore.

You're better off eating a tidepod then facing one of these guys with a couple times.
