At first these guys are passive and tame and can be given any type of berry. (Mejoberry is recommended) do not run up to its face. It will run away and it will keep running.(other monkeys near it will also run away too) simply crouch and feed it berries. Once tamed, they will love you forever.(they are a shoulder mount so put them on your shoulder and take them EVERYWHERE) they have a really cool ability to through poop at the enemy that is chasing or if it is your target. When it through the poop if it lands it will disable there ability to sprint for a little while.( and will take small amounts of dmg too while the poop is on them). I hope you found this guide helpful.

Always stay crouched while taming. And never get close enough to touch it. While following the monkey, if the monkey ever stops, its very likely It will turn and start to walk in a different direction. So be aware that it might walk in your direction. Hope this helps : )

If you sneak up behind it, give it a mejoberry, then back straight up... over and over again... you’ll tame one. Took me forever to realize that.

This creature may seem frail and weak but once you tame it you will release that it has access to the most powerful weapon on ark THE POOP CANNON

I feed one of these things a single dodo kibble (on mobile) and it tamed instantly without any other factors just a heads up for those of you who don't like wasting time

EASIEST WAY TO TAME ON MOBILE!

- Make pen or roofless structure

- Hop on a flying tame that can carry a meso

- Find meso

- Pick up meso

- Take the meso back to your base and drop it in pen

- Make dodo egg kibble

- Put kibble in hot bar

- Crouch and sneak into the pen

- Go behind it and feed it the kibble

- Then name your new monkey friend!

The mesopithecus is able to open doors when there locked when attacking the door or trying to escape from the inside out

These guys are legit pigeons I fed one and 30 more came.

I went looking out for a chalicotherium, came back with a mesopithicus, named it George, gave it a hide hat, now we can take on the world.
