These thing aren’t particularly hard to tame, but there not super easy either; if you ride a small, fast mount it’ll fear roar it and kill it. For a trap you should build a 2by2 stone build with Ramps, but you could build a 3x3 to be safe. Their fast but not to fast, so I recommend trying to get as close as possible to your trap when trying to get to aggro on you into the trap, so you can get in the trap before it hits you to much, then just traq it till it knocks out and give it some prime. You can get prime in the arctic by killing mammoth or carnos.
