How do scientists know that dinosaurs are carnivore?

Answer 1

It was a herbivore because it was formed with flat teeth not sharp teeth, which would be on a carnivore.Also,you wouldn't expect a HUGE animal like a Brontosaurus to run and catch another animal easily like a T-Rex would.

Answer 2

Triceratops did not have the adaptations needed for a predator, which include speed or an ability to ambush, sharp teeth to capture and kill struggling prey, or sharp teeth to tear off bite size pieces of flesh. Instead, they had many adaptations for consuming and digesting plants. These include a beak for cropping leaves of plants, and a battery of molar teeth for chewing plants (chewing is not necessary for carnivores).

Answer 3

Scientists can tell primarily by looking at the teeth and jaws. Powerful jaws with pointed teeth indicates a carnivorous dinosaur, while lightly built jaws with a battery of teeth for chewing or leaf shaped teeth for plucking leaves suggests herbivory. Other adaptations for hunting include sharp claws, binocular vision, and long legs for speed. Adaptations for herbivores include a large digestive tract, for fermenting tough plant materials.
