I’ve tried to tame 2 of these but there food never goes down when passive taming. As soon as I passive feed it once it never lets me feed it again. Any tips

Player-written tips for taming, using, and fighting the Dinopithecus in ARK: Survival Ascended & Evolved.
They are a forced to be reckoned with
They are really good caving creatures
They are better than Rexes at Boss Fights
The Boss on Lost Island's minion monkeys throw poop. EWWWW!
To take these you want to single out the one you want in the pack by killing any others around it and then it won’t fight back or run or attack so then build around it preferably spikes and it won’t hurt it’s self and you can take real quick
If you build a taming pen and lure 2 of them in there you'll only need to kill 1. Shoot the other one with crossbow until you dealt enough damage to tame him
JUST YO LET EVERYBODY KNOW THESE VERY EVIL MONKEYS SPAWN IN THE VALGUERO RED WOODS!!!
They now spawn on valguero
Probably one or favorite “dinos” once you tame one, it’s a walk in the park to tame another. I find it easier to build a trap and lead the pack in. Kill all but alpha, and shoot the alpha few times and mutton or kibble on hot bar. Bam Bam
It uses exceptional kibble. It’s also a passive tame.
We’re be able to vote for carch agian
Poeple who wanted carch: wooooooooo yea baby that’s what I’ve been what in for thats what’s it’s all about wooooooo
These guys don't only spawn on The Lost Island, but I've also found them on Valgeuro, and they might also be found in other maps.
When you throw them out of a cryopod they poop twice, I don’t know if it’s a glitch or a console thing but it happens to me all the time, not complaining though, when I’m breeding Dino’s I throw these guys out of a cryopod and get some poop on the side for my dung beetles
They also spawn on valguero. Idk why it doesn’t say that here. Probably in the redwoods but I found them below chalks hills near the world border
These things are great
They climb structures and trees at a very high speed
The stats are very good
They have great mobility
Speed
They can throw poo and grenades
The only thing is that when they take damage, they stop moving for a sec
My brother and I were taking them and as well as the killing the troop method discovered you can tame a female with a baby too with out all the killing
Anyone else having a problem with breeding??
Mean monkeys are mean. Just saying.
Be careful using this guy.if they get attacked by fast attackers like raptor. They will get constant stun and cant fight back..make sure keep some distance and attack
“Poop disables tek”
Me: the anti tek turret????????????
To tame:
Find alpha of the pack.
Kill other dinopithecus in the pack.
Get dinopithecus health under 85%.
Feed meat.
