Its the most aggressive herbivore, so be careful ! It's a classic knock out and it eats berries or megalosaurus kibble which I really recommend because the tame takes a veeery long time. It also loses torpor quite fast so you're gonna need a lot of narcotics. But once it's tames, you got a real beast: it can mess up against the rex and is a farming machine. Leftclick for wood and thatch, rightcklick for fiber and "c" for berries. It's the first herbivore that harvests bodies: leftclick for meat and hide etc. And "c" for only hide. You can increase the amount of gathered ressources by leveling up, similar to the moschops.
Not hard to tame them. U must come prepared. You do the hunting missions and get one bow that has around 300 dmg if im not wrong. Use that bow with tranqs you need wayyy less shots. Build a raft trap with stone door frames. Make a ramp and lure it into the trap. Dont waste narcos to keep ot down just look for some cnidarias, kill them and use bio toxin. :)
