The best way to tame it is to stand at a high point the shoot like any other dino then build around it a spike walls and let its food level drop near half while keeping it unconscious with bio toxins(make sure to take enough 70 just to be safe)

You can even explore a little around then when its food gets near half feed it any kind of meat doesn’t have to be prime and it will be tamed under 30 sec
