There are different kinds of dinosaurs for the same reasons that their are different kinds of birds and mammals.
Dinosaurs, like modern animals, evolved to match their environment and survive to reproduce. Some dinosaurs evolved long necks to eat branches off tall trees, and some dinosaurs evolved sharp teeth to eat other dinosaurs. Some dinosaurs evolved horns and thick skin to defend themselves against predators, and others developed thin frames and long legs to run away from predators.
The basic principles of evolution worked the same way for dinosaurs as they do for modern organisms. Dinosaurs evolved into such diverse specihowes because they were the dominant vertebrates for over 160 million years.
