This creature is fairly easy to tame, as long as it is alone. If in a herd, these dinosaurs will use their powerful stomp attack. It is best to wait for one to leave the group, and try to run it into something, such as a rock or tree, so you can hit it with tranq arrows. Once knocked out, its pretty much a straight forward tame.
In a group they attack, individual they run. Pick the lone wolf and lead it by facing the way you want it to go and trap it against a wall or rock or a safe place. No missed shots, no wasted resources, and a easy Morrelatops tame.
Okay so me and my brother were playing scorched earth and really wanted one so we used a strategy that worked. Depending if it’s you solo or playing with other people bring a boomerang or two for each of you (or just you) and find one a little away from its tribe if solo, but if not playing solo just corner them, then spam them with boomerangs and it will knock them out. Same for solo(CAUTION TAKES A LITTLE WHILE TO TAME)
