Create a 3x5 taming pen at least 3 walls high with wooden ramps at one end. While on a flyer, gain aggro and lead the Allosauraus up the ramp and into the taming pen. Then Tranq away.
If you can kill off the two weaker Allosauraus in the pack that you do not wish to tame then do so, it will make this method easier to perform. The easiest way to kill the other two is with a long neck rifle from the back of a Quetzal platform saddle.
Think about this: The taming in ark is crazy. The last thing the Dino would remember would be you impaling it in the face with toxic arrows before it gets knocked unconscious. And then somehow it eats while knocked out which makes no sense and then wakes up and loves you till it dies.
I consider my self extremely lucky with these guys bc I saw a pack get killed by a bronto but the lowest lvl one got stuck right before the fight so I tamed her and named her alpha and 20 lvls later she and her new pack took revenge on the bronto
