How much did dinosaurs eat?

To stay alive, larger animals need more food than smaller animals. But it also matters whether an animal is warm-blooded or cold-blooded. Since we aren't sure about dinosaurs, figuring out how much food they ate is not quite so simple.

Warm-blooded animals have a higher metabolism: they need more food to stay alive. Cold-blooded animals have a lower metabolism: they need less food to stay alive.
