Herbivores
I think plants because dinosaurs that have flat teeth eat plants
those that grind their food, which would be herbivores.
They only eat plants.
FLAT
they have flat teeth
Dogs
Animals with hooves usually have flat wider teeth for grinding in back of the mouth and roundish front teeth for pulling. Members of the deer family have only bottom front teeth.
becuz you are a stinky monky!
Cow
Animals that have broad and sharp teeth in the front, followed by broad flat teeth inside are likely herbivores. Some examples of such animals include cows, horses, and elephants. The sharp front teeth help to cut and tear vegetation, while the flat back teeth are used for grinding and chewing food.
Just about all herbivores - plant eaters - have at least some teeth that are strong and flat.Herbivores and omnivores have flat teeth in the back of their mouths called molars and premolars. These teeth are used to grind plant-based foods as an aid to digestion.
If by round, you mean 'not sharp' that would be most of the vegetarian animals, such as: cows, deer and koalas. They have wider flatter teeth in order to chew plants, grass, leaves and vegetation, kind of like the molars humans have in the back of the mouth.
