If the deinotherium is taking beer but you are getting no taming progress, put only 1 beer in your hot bar. - Lyx

Ok so basically you HAVE to be level 95 to tame. Put beer in the last slot of your hot bar, then it will sniff around (meaning it notices the beer) and find you. Look carefully at its trunk as it will roll its trunk up. It’s ears will also stick out. Go to it and feed it beer. Repeat the step. Also don’t go to the Deinotherium when it’s trunk is out and it’s ears are out too. Kill the other Deinotheriums in the pack (sorry for not mentioning that earlier) I believe it also looks different when male or female. Hope this helps.

1) separate from herd and other bigs herbivores. (when he gets the green aura they were also attacking)

2) set up a building at least 5x5 or have a shoulder PyroMane

3) approach him from the back and keep 15m

4) watch him shake like happy boi until his ears do uppies

5) when they do uppies run at his leg and circle it in the outer side to avoid stun stomps

6) swap to rider mode or run into building via dino gate

7) huddle in middle of building until he isn't angry boy and has started wondering off or leave render

150 is at 40% right now and it cost 5 Beer Happy Hunting ~Macha Misae

Yoi don't have to actually add up the animations. As long as they do one of each of them, in any order, you're good to tame. Head shake, trunk shift, and ear flap. This thing could do 3 head shakes in a row and then do an ear flap and trunk shift, you're good to tame. It HAS to do all three animations or you get wrecked.
