I read the post about Bruce wayne I was like R.I.P. in Bruce's honor I shall tame and breed a carno and name him Bruce Wayne then he shall carry on once more.

R.I.P. Bruce Wayne my brother in arms

For the real tip though you if you can just find a level 15-17 it should just take you 2-5 tranq arrows with a bow or at least with a master craft bow I just hid behind a rock made tranq arrows and went around the corner shot him 3 times and he was knocked out however I was all the way in the south of the map looking for a cave so I had to try and fit him on a raft which was a huge pain in the butt.
