I see a lot of debates on how to tame this creature, so here’s my way(the most mediocre ark player)

Prepare of course, you need..

6 STONE triangle foundations

12 Stone doorframes

2 Wooden Ramps

A LOT of Narcotics and i mean a LOT, like you could drown Colonel Sanders’ Wet Dream in it(its a giant chicken.. i’m not funny)

Quite a few tranq darts with a good Longneck

A fat pair of balls

Hide sleeping bag JUST IN CASE

Find a Therizinosaurus AND MAKE SURE YOUR TAME ISNT NEAR IT, these things are like spiders, you turn your back on them for one second and they disappear like a horror movie stereotype, Set the foundations up in a hexagon shape and place 2 doorframes on each side, add 2 ramps on one side(this’ll be used to get the Theri into the trap)..and set a hide sleeping bag close to the trap incase you need it

This step takes a big pair of balls, fire at the Theri and let it chase you, run up the ramp and make sure the Theri does too, run out the doorframes and then the Theri will fall into the trap.

Knock it out then stuff it’s inventory with extraordinary kibble and narcotics, don’t leave it there or else it’ll wake up because Wildcard wants us to suffer

Name your new Therizino! They’re great harvesting but they’re great for killing the Dragon, pair them up with Rock Elementals and Deinonychus and watch them shred that guy to bits and pieces

I saw alot of people complaining about the fact theri's being aggresive even tho it eats berries so to answer ur question i will say that u should go and stand in front of a wild elephant (which eats grass, herbs, ferns, leafs etc if u didn't know) and see wat happens and then u will know why a berry eating dino is aggressive against u

Yesterday I tamed a 130 with a desmodus and tranq arrows with a crossbow fed it crops and the Elixir.

I use 16 stone pillars in a box formation and stack it 2 high with a large bear trap works decently well and is pretty cheap. You could only it use only 8 pillars and a large bear trap to make it cheaper. All you have to do is setup the box and leave it open put bear trap in the middle and have it chase you into the trap and simply slip through the gap in between the pillars and when it’s stuck in the trap go behind it and use the last 2-1 pillars I have and seal it in. Works great I’ve used this trap for other tames such as wooly rhinos and a yutyranus probably works for rex’s too.

Stand on a tall rock and shoot his face.

More words...

These thing are annoying to tame they eat so slow there torpor drains so fast they knock you out on your mount and kill it I just recommend kibble because it takes so long and you cant leave it for one second because it’s torpor.

Make a 3x3 stone floor surrounded with 2*height double door frame. This will make a cage that you can enter and get out simply but not the therizino. Then add some rams/stairs leading into the cage. Lure the therizino into the cage and knock it out easily with tranquil arrow. This cage trap can be built on a raft as well.

If you want to tame do this(without any trap)

1.you must need 20-30 tranq arrows,50 narcotics,100 berries

2.stand on a mountain and shoot at it

3.it will went down and feed it berries

4.give narcotics (of needed)

The starve timer was off 2x event, I ended up only getting 64% effectiveness and it took waaay more food and an additional 20 minutes to tame. Used all but 1 kibble I needed cause I was short 1

(For mobile) Tamed a level 405. How? Grinder amber early game and bought the cooking station. Got ready a soothing balm until I have the right equipment. The equipment is either compound bow—get a ascended one from quest, with toxicant arrows, or a longneck rifle with shocking tranq darts. Make accordingly following the demands shown in this app and get 6 megalosaurus kibble from the cooking station. Get around 5 large bear traps. Set them up and shoot ‘em while luring it into ur bear traps. Once knocked out, feed the balm, than the kibble. There. Ez 400+ lvl theri tame

i am so angry right now. ok so i knocked out a therzino today in the water i was like oh no it’s gonna drown then as i fed megalo kibble and the first feed was 26% then i thought everything was ok since it wasn’t drowning then i gave it soothing balm(10x) and waited. ThEN A SARCO KILLED IT i killed it with my ascendant sword but then the therzino died…. moral of the story don’t knock a therzino out in water

I recommend having a flyer for this one... I am I think level 54. I have a pterandadon, I just kept shooting this bright blue female thera, then I would fly away and wait until she left me alone again. and in no time at all she was locked out. PLEASE BE PREPARED. They’re torpor drain is high! Bring at east 200-300 narcotics/80-100 bio toxin for a lower levle.

You should use kibbie,using crops takes a ton of time,I think 1 hour

At first they are really scary and really op let's be real. But once you find out you can easily knock one out with about 30-50 tranq arrows. They stop being so scary. Easiest way is probably to craft 2 big bear traps place them next to each other lure it into them and then just knock it out. If you can't craft those yet. Then I recommend trying to get on a Big o rock that it can't climb and just shoot it from there. They take a long time to tame unless you have a soothing balm.

It took me forever to tame one because they recover way to fast, though if you just sit there and feed it narcotics and mejoberries you can eventually tame it.

This thing killed all 5 of my raptors *cry* and went around the bear trap I’m scared to tame it now

Who else thought that this was tamed with meat

No idea, why people are so scared of therizinos, they aren't that hard to tame as well, simply build a stone trap, lure it in, tranq it uses tranq darts or tranq arrows, one its knocked out shove mejoberries or kibble up its ass, enjoy your new slave. (also theres a setting that increases the torpor wild or tamed dinos get)

If u are trying to tame this beast, use some darts from a far distance

Just tamed up a max level with nice stats and amazing color on medium. Strangely.. like he would like to be a pet, cause he barley fought back. The little what I’ve got my Baryonyx tanked with ease. Interesting experience as all the other Terrys aggro me without hesitation.

I used 20-30 tranq darts, ascendant longneck, 10x shooting, Megalo kibbles, spike walls and my mate on his OP Spino to protect the area.
