ALL YOU NEED TO KNOW: Therizino

It's VERY AGGRESSIVE, has High Health, High Speed & High Damage output.

Avoid at any cause til you can tame them cos these guys are endgame boss killers and are not worth the trouble unless it means you can bring one back home.

Trap them easily by placing 4 stone foundations and 1 wall high all around except on one of the sides, which will leave 2 walls off, bait it in there while using a flyer, high hp pteranodon or an average hp argentavis, while it's in there with you, quickly place those 2 last walls on that one side and it's trapped, fly out. Kill any carnivore around the place to make sure it doesn't come and ruin your taming.

Knock these guys out using tranq arrows or darts, tame them with mejoberries, also have a steady supply of narcoberries cos you gotta need to forcefeed them around 1500-2000 just to have them stay down, don't forget to put down spike traps around it when it's knocked out cos some aggressive dinos will attack it, better be safe than sorry regarding these guys.

Tame level 125 or above therizinos til you get one theri with 8874 HP or above, and one theri with 330 Melee or above, breed them wil you get 1 female and 1 male with the high hp stat and high melee stat.

Breed those 2 til you have 16 in total not counting the ones you are breeding.

Level those 16 guys up in hp and melee and put about 20 veggie cakes in each of them, and ofc use the best therizino saddle blueprint you got.

Use these 16 theriz with 1 mammoth, 1 yuty, 1 deadon and 1 rex against all bosses.

The rex is meant to take aggro from the theriz and yourself since theriz counts as a medium sized dino and bosses will aggro on the largest tames first aka your yuty or in this case the rex instead.

This gives you some space and time for you to switch between using the mammoth debuff on the boss and the yutys buff on your own dinos, also giving you some space to use deadon to heal you theriz even more which will save some of the veggie cakes. since they can be hard to come by in such a big numbers.

Theriz harvest hide, fiber and wood extremely well making crafting saddles and building huge wooden bases lot easier, combined with a doed which harvest stone, one of the best stone structure gathering duo in Ark Island

There you have it.
