They take a lot of narcotic arrows to put down have at least two bolas at the ready you need about 15 narc arrows to the head for a level 5

Bring a megalosaurus and nab the alpha then run off, you can set in trap to knock out or have a tribe mate shoot narcs while holding. Up this to save lives

Watch out if they have an alpha boost or mate boost! You'll need more tranq arrows.

Make sure you have a frind or have a lot of bolas or you will die

Change my mind bring bolas no mater what

If you throw the bola and it hits its mouth, it breaks and does nothing.

Don't skimp out on resources for the trap since a few high level ones will destroy wood but a stone trap is very reliable

If you use mutton, make sure you cook it. Your ravenger will tame faster.

I would suggest bringing 5-10 bolas and a decent health and/or attack creature, and killing all but the one or two highest levels in a pack, then using bolas and taming one. Also bring LOTS of tranqs, took me about 30 hits on a 150 to down it

One tips : bring many bolas as you can and use sheep meat its op 👌🏻🐑
