Easiest way to Tame this guy is to first build a trap. I used just 4 behemoth gates (metal) with doors on each side. I left some room I could easily fit in and out of. Bring your own tames to feed this guy, I used 2 decent lv shadowmanes. Once they're dead drag them into the trap in the opposite direction it is facing, once it does its sniff animation drop it and leave so it can eat. As soon as the bar that appears is green you can run up and ride him. Open your trap, you have 10 minutes to kill everything in the area and get him tamed!!
