For taming (on unofficial) I found a way...

Wear your armour take your best longneck (I use asc 240 and it works with decent riot set) and shocking darts also take very good pump shot-gun and fly around redwoods in flyier...

When they pounce you spyglass it and if it's bad lvl kill it with shot-gun if it's lvl they you want shoot him with shocking darts and fingers crossed that you can do it (if u have like at least 800def, like 200-250HP and 180 longneck (have to use shocking) it will most likely work) u can also take some med brews just to be sure he won't kill you.
