During most of the Mesozoic, the era when non avian dinosaurs lived, grass didn't exist. It first evolved in the late Cretaceous. However, their have been dinosaur coprolites (dung fossils) that contain grass. But grass only lived near streambeds during the Mesozoic, and wasn't abundant enough for any dinosaur species to solely eat grass.
yes
So that they had the nutrients and proteins there bodys needed to survive, like how humans eat cows, or cows who eat grass.
Grass only evolved late in the Cretaceous period so only the dinosaurs near the end of the age of dinosaurs would have had grass available. Remains of early grasses have been found in dinosaur coprolites of this period.
None. Dinosaurs went extinct before grass evolved.
No. Wheat is a type of grass and there was no grass in the time of the dinosaurs.
Carnivorous dinosaurs would eat other dinosaurs.
many types of dinosaurs eat all sorts of plats. Especially TIGERS!!!
mammals have evolved and that climate has changed rapidly like grass, grass wasn't around in the time of the dinosaurs.
If you're asking what carnivores eat they eat meat. Like other dinosaurs.
Yes. Some crocodilians did eat dinosaurs.
Grass rats eat grass.
One clade of dinosaurs, the theropods, were carnivorous. Many of them were large and ate other dinosaurs. Today, birds are the only surviving group of dinosaurs. Some birds of prey eat other birds, so dinosaurs still eat other dinosaurs today.
