These are beast, they rival rexs, so if you are trying to tame one,look near mountains that have jungle around the bottom of the mountain. I usually find them there.then, when taming,keep in mind that they suck at going over rocks. Find a huge rock, get on the rock, shoot the therizino.
This thing is a pain in the ass to tame! I knocked one out and made a pillar trap around it so I wouldn’t escape. I came back after I got my narcotics and it was killed by a pack of raptors, I’ve never killed anything so fast 😂. I ended up finding another one and knocking it out I spend nearly a while two hours getting to to starve then I didn’t have enough narcotics and it took all of my carrot! Be prepared for anything with the devil chicken!
