Types of dinosaurs

Dinosaurs designs were varied and spectacular. A group of dinosaurs called the sauropods were the largest land animals that ever lived . The smallest dinosaurs were dog-sized. Large or small. All world have been wary of hungry meat eaters. Some dinosaurs had armored skin for protection. Others were fast runners and could escape predators  by fleeing to safer ground .

 Tyrannosaurus rex 
and other fierce meat eaters
 had huge, 
sharp teeth with 
witch they killed prey.
Herbivores 

There were many more herbivores (Plant eaters) than carnivores (Meat eaters) in dinosaur world.
A herbivore called Stegosaurus had a sharp beak for cropping leaves off plants.

(Compsognathus reached just  below Barosaurus's ankle).

Compsognathus had long lgs for running fast.


Edmontonia
Spiky Protection 
The slow-moving ankylosaurus, Which were herbivores,had armored skin for protection from sharp-toothed carnivores. Edmontonia had bony plates and spikes on its skin. It lived at the same time and in the same places as Tyranosaurus rex, So it needed all the protection its armor could give.
