A simple way to knock it out is to build a 3Ã—3 room with a gate lure them in with a pachyrhinosarus inside then calm them with the pink stuff and just tranq them make sure to keep them passive to have an easy knock out ;)

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.
