What I did is I found one and ran up a steep mountain and they couldn’t come up their with me so I knocked the high level ones and killed the low ones

If you have a group of 3 or more tamed then the highest level will become an alpha which will give it a new attack and bleed effect.

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.

1= easy tame

2= bit hard to tame together

3= impossible to tame together

4= death of you

5= crying behind a rock waiting for them to go away

6= alpha tribes dying and going extinct

7= ultimate giga killing squad

THANK U FOR READING

I recomend you ta me a female and a male and make babies because they will form a group and become stronger (Sorry for bad English i Am Brazilian)

if u are going for an allosaures tame the easiest thing you can do is lead one into a taming pen and then kill the others outside that way they do not have the alpha pack boost affect and you can easily and safely knock it out

Just get 4 stone gates 4 reinforced stone gate

Place them like a rex trap but with gates step one done

Step2 Find a high level get it to follow u close the gate behind it

Step3 the a lunch break

Steps knock it out feed diplo kibble or prime wait for that bad boy to tame up

And boom you got yourself a bronto killer

Last step Find a mate and make a allo army

Expect double to triple the suggested tranqs

Shooting them with a net from a harpoon gun works. Up so more see this
