I literary tamed 4 of them. They are really hard to tame or easy i don't know but they're strong
Therizinosaurus
The Therizinosaurus (or "Tickle Chicken") is a swift, clawed herbivore prized for its versatility. Its specialized strikes make it an exceptional resource gatherer, while its strength makes it a powerful combat mount.

How ARK players tame and knock out the Therizinosaurus: what to feed it, what to knock it out with, and how to keep it safe.
Narcotic only last ten seconds before needing to apply it again. Watch the torpor and adjust accordingly. Should bring between 100-300 narcotics, it will be a slow grueling process.
just spent an 1h and 1/2 trying to tame a lvl 15 therizinosaurus, used majo berrys and i used around 150 narcotics to get it to 44%!!! how much am i going to neeeeedd? dodex said 44… that was awfully off lmao> it eventually woke up bc i couldn’t keep up
You need only 4 things
1- a trap easy to build
2- bed near the trap
3- something to knockout
4- any type of food
After you trap it and sleep one time it will be starving ( zero food ) and give him berries and after 5 min it finish taming and cong now you have a tickle…
