Herbivores Herbivores, or plant eaters, were dinosaurs that ate plants, leaves, fruits, grass and flowers. Anything green was considered a meal for these dinosaurs. Their movements were usually slow as there was no need for them to chase after their meals! Shorter herbivores tended to feed on grass and low lying plants, while the taller ones or those with long necks used to feed on leaves of trees. Herbivores usually had blunt teeth that are good for stripping vegetation (leaves, twigs, etc.). Some also had flat teeth for grinding tough plant fibres. ! osaurus Lambe 10 | SPARK Herbivores ate whatever vege ta Most herbivor es ate one par tion they could find. ticu some ate man y different ty lar type of plant, but pes.
