Foraging
The plants that herbivorous dinosaurs can eat are limited by their height, so some small herbivorous dinosaurs will stand on their hind limbs in order to eat high plant leaves. Carnivorous dinosaurs fed on herbivorous dinosaurs and other animals. The different foraging methods of various dinosaurs are also reflected in their teeth.
Struggle
Sharp teeth and claws were weapons used by carnivorous dinosaurs for hunting. Tyrannosaurus dinosaurs would seek out lone herbivorous dinosaurs and often travel alone. Some dinosaurs would move in groups, lock onto their prey, swarm up, and cut open the prey's abdomen with the second finger of their claws.
Herbivorous dinosaurs generally have some special "equipment" to deal with attacks from carnivorous dinosaurs. These equipment are sometimes tough leather armor, bone clubs or bone nails, and sometimes they are powerful tails. Such as Bang Chui Dragon and so on. Large herbivorous dinosaurs would act in groups and, if threatened, would collectively stand their ground and fight back.
