I learned that u can use a rocket turret to knock it out.all u need is to be on a medium sized cliff or a tall structure and a rocket turret on the top,and FIRE AWAY AT THE HEAD!and once its knocked out just put the saddle on it while its knocked out.I want to make sure people see this.so pls up this.
To tame it you need to equip a Titanosaurus saddle on it. The engram for it is unlocked at level 100. For pursuits which is only available in “Ark mobile” You need to do the “Hunt Giganotosaurus“ quest which gives you the saddle. I hope this guide was helpful for you.
