To random lvl 37:

High ground, mejoberries are among the best, narcs to use are bio toxin (around 250+ or so, depending on the level, to get just kill the jellyfish) crossbow is alright, but tranq dart would be better. Go for the head, check hp always with a spyglass, then let it recover a bit if its health is too low to prevent you from accidentally killing it. Make sure the high ground you’re on is a CLIFF facing big rocks (this thing can walk over rocks so watch out for that also can push trees out of the way, dunno if that is a glitch but whatever). Always have a flyer at the ready, ptera is good. Taming pen is a bit hard because this bastard can damage stone with its beak attack, which can also give you torpor if it hits you. Also equip a shield, just in case. Saved my ass from lvl 130+ theris in case a hunt went wrong. Best armor to use is flak, no more no less if you wanna fight this guy, tho it can melt flak and also pierce straight through that. Pissing it off then climbing to a nearby rock a sarco can climb on spells instant death for you. Killing this as a lvl 37 is impossible without a good sword and shield at the ready. Spino also takes good care of killing this bastard. One mark for a therizinosaur is if there’s too many herbivores in the area that should normally be filled with raptors or terror birds. You’re gonna need a ton of tranq arrows to knock it out though, with a certain chance of death.

If you tame one of these and put spike walls around to protect it while taming beware titanoboa can come right through the spike walls and attack like they are not even there. Also clear the small plants and underbrush away so you can see it coming because they can sneak through the plants and attack your unconscious tame and you won't see it until too late.

When tamed make sure to get a saddle for it Because it can collect fiber like Alot

When I was playing ark I saw this thing and i was staring at it and immediately ran when I saw the dangerous animals nearby sign

For me they are on almost every coast in the south of the main giant island. My tip is to fly. Plus I was able to tame a pteranodon with 20 narcotics plus about two or 4 used. So maybe not so much narcotics with terizino. They aren’t agro unless really close or shooting at them. They fast/slow fast attack kinda slower than at least 400 speed and about 300 stamina fir human or pteranodon

135 theri killed my level 145 carno and 162 raptor😫. Be careful guys

First time it ripped me in half second time I put a large bear. Trap on the ground and shot it while it was stuck from a high rock then I shoved mejoberrys down it’s throat.

⚠️WARNING THERE TOPOR DRAINS HELLA FAST ⚠️

Just found out these guys can gather black pearls.

They wake up quick and angry so

Tamers beware! They're brutal and unforgiving. Build a 2x2 stone doorframe pen with ramps on the side. They can damage stone but only barely.. long enough to tranq em out! Just have plenty of narc on you. It's torpor drains quick.

I took this thing out because I have like 8 Raptors and a trike

I say a griffin will kill it or a titanasours best

I tamed 12 and put a saddle on them I thing they are great for war!

1. Get A LOT of trancs

2. Find a steep/or where it can’t hit you and you can see it (at least the small part of the tail

3. After finding the cliff face find a theiz. Near or right under you

4.Part 1) Get kibble and a good soothing balm (I prefer the major than the minor) (I friend with the regular one but the other drowned and took both the kibble and soothing balm TwT) btw it only takes one kibble with the major balm

4.Part 2) get enough food and a small or any balm tranc it and for this you HAVE to have a lot of narcotics

5. After knocking it down DO NOT LEAVE IT FOR OVER A MIN! It will wake up IMMEDIATELY so warning about that before you go all “O NO I HAVE NOT ANY FOOD ON ME, LETS GO GET SOME!” And don’t feed it flowers it will wake up and start running again I have been though that well I force feed it because it would not eat it.

Tip #1: have somewhat of a flyer so no need to travel on foot for that will take longer.

These things torpor drops way faster in mobile if your on single player just knock out a low level one these will break all your armor up if helpful

I saw one and thought it was passive and it killed me soo ya

RUN FOR YOUR LIFE IF U SEE A FAT TURKEY

2x3 stone fence foundation. Stone dino gate on one end and doorframes 2 high the rest of the way around. Bother it, run into the trap, out the doorframes, then place the door on the gateway and start shooting. *DO NOT USE A COMBINATION OF DOORFRAMES AND WALLS FOR YOUR TRAP, IT WILL WALK THROUGH THE GODDAMN WALL LIKE NOBODY'S BUSINESS*

If you see one then make sure you have LOTS of trang arrows or a gun at trang darts o and one time when I was a big noodle a bunch a piranhas came and tried to eat me and my dino saved me and it also died fighting I was very sad after that

Stay away from these things if you have a ptetanodon agro it and drive it away from your base it will destroy you.if you don't have a ptetanodon relocate other on to high ground where it can't get you and shoot it down or there are tiny places big enough for a survivor to get in not a therizinosaur.Get in there and kill it by shooting it.

If you happen to meet a therizino, there is only one fling to do. RUN! This guy can damge as much as a T-rex if its in a high level. (btw this guy is amazing to gather wood and fiber with)
