If you are going to tame one of these with no dinos, be sure to upgrade your movement speed and get tranqs. When you see it whip its tail forwards move to the right you will dodge the shots. This worked for me.
If you have a flyer carry one to a taming pen, it's gonna aggro and start throwing spines at everything it sees the minute it lands. Plan accordingly, and use solid walls so it can't shoot through them.
For me I tamed him on ark fjurdur in balheimr I used a argentavis to go to a high area and then I started shooting him with tranq arrows it took me like 14-15 tranq arrows then I gave him raw prime meat and then I tamed him. Hope this helped. Good luck for everyone taming him.
