To tame this guy, you may need some stuff that can't always be accessed at the start, however do not be sad yet because sometimes, quite often actually, you will find one that eats simple things like tintoberries. Tame it and they will be a very useful collector. They have three attacks (left+right click and c) they are all good for collecting. The moschops, similar to the therizinosaurus, has harvesting levels that you can put into the many things it can harvest. Also keep in mind it is omnivorous
