Today we are going to talk about the diets of dinosaurs and how you know what they eat. We are going to start with the small dinosaurs and go to the bigger ones. We know what they eat from their teeth sizes and shapes. Most small ones eat little lizards but some steal food that a bigger dinosaur has. The bigger ones usually ate fish or other dinosaurs. They mostly ate vegetarian dinosaurs because they didn’t have to fight them as much. The vegetarian dinosaurs mostly ate from bushes or trees. The underwater dinosaurs usually ate fish too.
