What I did is take out its pack with my argintavis. There was a 120 and I wanted it so first I got it's pack to attack something so maybe the weaker ones were taken out, then attack the rest of its pack, when they are all dead the strongest one will be quite hurt. Wait about 10 minutes then tranquillise it with a longneck rifle. This will take some time so bring a few bola's and a dinosaur with lots of health if it turns around to attack you don't panic, simply get a spare bola and trap it again, you will take damage from this so as soon as its free trap it, if it attacks you keep swinging the bola and DONT run away because it's faster.
I think this creatures are too strong... my friend and me see a group of wolfs (we play on ps4) one lvl 140 another lvl 145 (on ps4 is max level of wild dinos 150) we bola all of the 4 wolfs, kill the lowlevels and tame the good ones. After tame we have a women and a men of wolfs (lvl210 and lvl214) and without more skilling they make 654 damage!!!!!! I think the Direwolfs must be not bolable. they opopopopop fithing dinos and very easy to tame. i hope you learn about this tipp and rate 🔼 this to other players see this (we have over 6 wolfs (breeded) and he are verrry strong) (tip: tame so many you can)
