I recommend having lots of hp to knock this thing out. I made this dood my starter tame (no seriously I tamed a male level 1) and I used my fists. If you have high hp I recommend doing these 6 steps

1st: run as fast as you can towards it

2nd: jump and punch its head

3rd: punch it in the legs while its warming up its attack

4th: when it starts attacking punch it in the claws (in water)

5th it runs really fast so just knock it out near a rock

Finale: feed it keep in mind his unconsciousness drops fast either feed it narcos or punch it a few times and plus my therizinosaurus name is scratch.
