Dinosaurs are one of the biggest animals in the world. Some of them weer also tiny and medium sized.
All of the dinosaur herbivores were big, small, and medium sized. Even though they're all herbivores yet they still kill each other. They even kill their own species at times.
Carnivore Dinosaurs are almost the same as the herbivore dinosaurs. The difference is that they carnivores and herbivores. Basically they will eat their own kind to survive.
Basically dinosaurs are giant reptiles. They eat each other and kill each other. I guess you could call it survival of the fittest if you like.
Hope you enjoyed.
