Basically what you need to tame on is first see one then run in terror , then prepare, Kibbles is must ,next thing they like are you narcotics so stock up , make some metal gateway, then ammo of your choice, keep it like there is no tomorrow.

Now make the trap a rectangular cage [__] like so place some large bear traps ( i placed 5 but 2 will work) . Lure it in with a fast mount like a gally or raptor. I used griffin

And when stuck in the bear trap put the last side of rectangle. And then let it try to escape. If done right it won't but if it did RUN!

When trapped , make a lot of distance or shoot at its butts. This will chomp in the island and kill you in the aberrations . They earn there reputation as almost a boss like creatures . After knocked out put you kibbles and narcotics, keep an eye on it, its torpor will go down rapidly so take that into account.

If you do it all correctly, you will have a monster which eats rexes and spinos for breakfast and craps therizinosaurus. But NEVER fight a wild one with a tamed one .people tried , there giga died
