How I tamed my Rex (tyranitar) I went to the volcano and got him stuck on a bump I shot him from there but first I tried to bear trap him but he broke out quickly my Argy nearly died but thanks to a saber tooth we got away I came back and start lurring him to another trap butmissedand got stuck and i tamed him now he keeps my diploclaus alive when sarco attack
If you use the bear trap strategy which is if you lead it into a Dino gateway that is shaped in a triangle and with a bear trap in the middle (Large Beartrap) and when it is stuck you must put a dinogate behind it to trap it and then knock out.
The Rex are very slow . Put a stone gates around him while he is stuck and use a bear trap then put the x3-x4 stone gates then tranq him out . Make sure you clear the area before setting the bear traps others creature can spring it and u would be left with using your self or a tanky dino for a distraction
