The Island map, I started my hunt on the small island of the south-western most location. I rode on my Baryonyx (level 38) and bumped into a Level 4 Therizino, I shot narco-arrow with my crossbow and it started charging towards me, that small island was covered with small trees, my Baryon can pass through in which that Therizino cannot, it got struck and like on a threadmill, I shot it with 6 more narco-arrowa and it fell alseep, but this monster needs hundreds of narcos, I only got 50 on my hand, so I grab berries nearby and started craving narcos, it took my 80-90 narcos to tame.

If this dino spawns near your base and you are low and mobile player then just do one thing. Put your all stuff in your base and go near the dino then run in opposite side of your base and lead him to far away from your home before he destroy all you have even your pets. just don't uninstall the game bcoz of this😂

Why does it break stones buildings! Up for devs to see this!

They are hard to tame but it’s worth it all I did is go on a high land high enough so it won’t hit ya then over load it with Trang arrows recommend crossbow not bow and they eat berrys even tho they sound like they eat meat THEY DONT REMEMBER THIS!!!

TAMING A LEVEL 135 THERI IN JUST 1 Minute WITH JUST VEGITABLES.
I don't know if anyone posted it before. But it could be very very helpful. I'm playing in single player.
But I wanted to tame a theri with 135 level what I did is that I trapped it in the stone walls and I waited till the night by this time I did not go close to him cuz they can brake stone so at night I took the sleep and when I gave him food I gave him only vegis with 10x speed and it tamed in just 1 minute belive me just 1 minute with 100% taking effectiveness. 😁

Knocking it out is the easy part. Keeping it down? Better have a few hundred narcs

It is not hard to tame a LOW LEVEL therizonossaur. Mounting one of your fast dinos (Galimimo, Raptor, Iguanodon is preferred) and search for therizono, remember to equip a lot of narcoberries if you pretend to tame using mejoberries. when you found the wild therizono just dismount and shoot narcotic arrow against it, mount again and run to gain distance and shoot again. Do this till you take this Dino down. NEVER STAY CLOSE TO IT, cause it will kill you easily, so distance is you friend.

I am a mobile player I play on the official server (Alpha) and my username is Doglife so if you see me say hi. I tamed one of these easily. My friend held me in the air with his pteranodon while I unloaded tranqs on the Theri. I didn’t miss a shot and soon enough the Theri went night night. We gave him a soothing balm and a bunch of mejoberrys and BOOM we have our self a Theri named Snuffy. You can tame almost any creature this way. Please like so people can see. :)

I’m taming one of these guys now so here is how I did it: in the western approach is a spawn of these chickens, most of the times they come in couples of 2. If you have a bird, lure the one you don’t want in to the sea. Make the other one attack you while you run to your bird. quickly Fly to the top of the Rocks, stand on a place high enough to easy hit it. Shoot it until it is down (this Will take Some time) if it is down put mejoberries or kibble in it. And immediately get narcotics or bio-toxine (The ocean is very close to this place so you can get a lot of bio-toxine from the jellyfish there) then the last step is wait for a long time.
Then i have a list of what you need:
100 tranq arrows, depends on the level.
200+ bio toxine, depends on the level.
500 mejoberries, depends on the level.
Optional: some strong dino’s to protect it

Hoped this helped guys!

Make sure to keep your distance when taming, as they usually one shot you! 😂
