Very easy to tame if you know what your doing. First tame an Ichthyosaur. Then grab a crossbow and some tranq arrows and find one and knock it out. It is not be able to attack if you are on the Ichthy. As you are taming it, be sure to remain on the Ichthy unless feeding narcs, so other creature don’t hurt you. Vote up if this helped
Just tamed a 140 X Dunky. Yeahhh, really recommend that you build a trap for these peeps, spent 40+ mins trying to knock out this bad boy with a decent crossbow all while dodging tussos ect. Good times, stressful but good.
