This is a little expensive but, I tamed one in a box by tranqin it when it woke it was calm and I was able to follow it around the box and pet it. Hope this helps

You can make them a meat pack wich works as a preserving bin.

Once tamed you cannot ride them but you can place saddle bags on it to act as a preserving bin and eating a dead corpse will regain its health almost instantly

Normally you can't tame the pack leader, so just get a pteranodon or argy, pick it up and drop it in a large area (like a separate section of your base). When you take it away from the rest of the pack, it removes its 'pack leader' title, allowing you to tame the highest level hyena of that pack.

Despite it's appearance, the real life hyaenodon was nowhere near related to actual hyenas, but it actually belongs to a group of prehistoric mammals, all extinct, that are believed to be most closely related to pangolins, which aren't related to anteaters or armadillos, for your information.

Does not gather fiber. Please remove this from resource gathering.

Build a 1x1 box with door frames and throw a hatch ceiling and 4 more regular walls up and throw it in, it's butt will hang down and you can crouch and pet it under it without spooking it. You CAN tame without alpha present but if it becomes spooked you have to leave your chunk and let it reset.

Basically follow them around and when there parents aren't looking pet them

I used a combat argy to follow them around till they got stuck on something. Tamed a 145 and 150 both times they just walked in place while I sat there and hit E every 30 secs. Don't leave the argy to close or they will continue to try and flee even while stuck.

If you're taming one on a server where you can't pick up wild dinos, make sure nothing is next to it because it will get scared and loose effectiveness

So I've been trying to tame one all morning, and I've come across this knowledge. Any type of armour is sufficient, I use chitin bc It's what I keep on me at all times. Use a Ptera, grab the Alpha, and fly it far from the pack. Set it down in an area that's open and scarce of other dino's, and park far away. Run up near it, but crouch before getting too close. Always stay behind it's butt, and crouching. If it turns, turn with it, staying behind it. 6 or so pets should do the trick, I have dogs ranging from lvl 20 to 140. Go for the highest level you can find, and ALWAYS stay behind it. After tamed, fly out w it to your base with the Pt. Good luck, and may the odds be ever in your favor.

They can jump through stone windows. If you have any Windies in your taming pen, close them before you grab these guys.

I haven’t found a single one in mobile!

On Scorched earth you can place a tent on them, follow behind it with the tent ready to set it down, the tent will be red but let it walk to an out edge and spam the place button. Once it's inside open the door it will pop it's head out as it walks around so just crouch to the side of the opening and pet it when it does. As long as your not to close to the opening it can't detect you.

Little known fact, they reduce the weight of raw meat from 2 lbs per stack to 0.8 per stack.

Dakronik's fun facts:

The hyaenodon will let you know a few minutes ahead of time that it is going to rain. It will notify you using a sort of whimper and bark.
Do with this what you will!

Just kill every single one in sight they give a stupid amount of XP and are easy to kill. Grab a XP boost and watch your Dinos level like never before!

It's a passive tame just creep up on one that's alone and it'll give you to pet it and once per enough it's yours if you want to ensure the tame get ghile armor

Very easy to breed. Make excellent cave divers. Alpha does over 1000 dmg per bite with 800% melee and a +4 pack bonus and mate boosted and petted.
