If it were so easy to create dinosaurs as they did in the story of Jurassic Park, there would not have been need for continued debates and discussion about theories of Dinosaurs, perhaps there would not have been possibility of survival till date of the writer or reviewer of this essay on this planet. .
We are today trying to study scientific theories of dinosaurs, as distinct from colorful imagination of fiction writers supported by multiple evidence discovered by paleontologists. .

"Dinosaur" reaches deep into our minds and drags out nightmares from monster myths. What is the truth about dinosaurs that underlies the awe that covers them? What does modern science have to say about the dinosaurs? Did Dinosaurs ever exist on earth?

We are trying to study in this paper evidence of existence of Dinosaurs and if they existed, what did they eat, what were their behavioral patterns, and also study theories about why and how did they become extinct from this planet .
Importance/Utility of study of Existence and extinctions of Dinosaurs: .
Finding the true reason for the dinosaur's extinction to many people is not an important matter. They do not care what happened to some reptiles 65 million years ago. But to many in the science world it is considered extremely important because it entirely changed evolution so global life took on an entirely new course of action. And finding out what it is may be important in turning it aside so it will not happen to the human race. .
Existence of Dinosaurs: .
Scientists have now firm belief framed from available evidences that Dinosaurs did exist once on this earth.
