  Millions of years ago before human being walked the earth there were creatures called Dinosaurs in earth. They dominated the earth over 165 million years. There were mainly two types of dinosaurs ''carnivorous'' and ’’herbivorous’’. Carnivorous were the type who ate only flesh and meat for their food, they used to hunt down others dinosaurs for their living. The herbivorous were those who only ate plants and leaves from trees and grasses. There were many kinds of dinosaurs walking the earth that time. Some were small and fast, some tall and big, some were very strong and deadly. No one knows what colors or patterns they were, how they sounded, how they behaved, how they mated, or even how to tell whether a fossil came from a male or a female dinosaur. Dinosaurs suddenly became extinct about 65 million years ago, which was a time of high volcanic and tectonic activity. There are a lot of theories why the extinction occurred. The most widely accepted theory is that an asteroid impact caused major climactic changes which the dinosaurs couldn't adapt to. All that's left of the dinosaurs are fossils.
