Tintoberries can them to that is how I tamed it
Moschops
The Moschops is a omnivorous therapsid best known for its love for food. Survivors can train it to favour specific types of food — whether it be Prime Meat or Rare Flowers — and it will become more effective at gathering it. The Moschops is a very cowardly creature and will flee from any sight of danger.

How ARK players tame and knock out the Moschops: what to feed it, what to knock it out with, and how to keep it safe.
You can tame them with mejo berries up vote
What it takes to tame these things has changed. We tamed a 135 and it asked for cooked prime meat and tintoberries.
Dododex forgot cooked prime meat
Stay with after first feed as if you leave them over time they will get injured and die. Not to mention taming goes down. Best bet is to have one person with and another collecting it's food.
Upvote to save a moschops
The moschops eat Mejoberries as well btw
Tamed a lv 150. He wanted Tintoberries,Mejo,Giant bee honey,Rare flower,Cooked prime meat,Raw prime fish meat and rare mushroom.
You can also feed it berries. But they will be specific.
I tamed mine with a mejo and a tinto berry so I don’t understand how and why I have one? I guess this helps people. So I’ll leave it. Also the moschops I tamed was lv5 so maybe that has to do with it.
The few times I’ve encountered and tamed one of these, they asked for Tinto berries the first time!
I tamed mine with Tintoberries!!??
To tame it you go up to it and fees it whatever it say. There is no exact food to tame it.
They seem to have altered the tame methodology recently. Very, VERY low level Moschops, 10 and below, will take specific berries instead. I'd just spawned in and was gathering fiber when a level 8 walked by with the blue text asking for a Tintoberry to tame.
Will now eat mejos and tintos because of the new update but bring a lot in case.
Sometimes they just take berries if there a high level.
Last two I ran into preferred rare mushroom after the first feeding so be sure to have a lot of rare flower and mushroom while feeding these guys because they really seem to like it
With 20 points in prime meat I can get 10+ prime meat from a stegosaurus
Almost wants mejoberry, cooked prime meat, an giant bee honey
Create 4/5 fence foundations, walls and one door. Bola the Chops and build around it. Enjoy your new pupper.
Bring all wanted food for your tame 20 or 30 times over
