Dinosaurs were the dominant land animals on Earth for much of the Mesozoic Era, and they are also some of the main subjects, in Jurassic Fight Club. Dinosaurs ruled the Earth for 160-170 million years, in their reign. Scientists used to believe that all dinosaurs were extinct, thanks mostly to a meteor impact. However, it is now thought that modern birds are in fact the living descendants of dinosaurs, and have so much in common that they should be classified as a type of living dinosaurs.

History Of Discovery Edit

Dinosaur fossils were first discovered thousands and thousands of years ago, in Ancient China. The Ancient Chinese civilizations thought that the dinosaur fossils which they had been discovering were really dragons' bones. Many years later, in the early 1800's, scientists first began to study dinosaurs, really, for the very first time in history. The first three dinosaurs ever to be discovered, Megalosaurus, Iguanodon, and Hylaeosaurus, were all discovered, during this time period. Later on, in the latter part of the 1800's, two palaeontologists, Othniel Charles Marsh and Edward Drinker Cope, discovered tons of dinosaurs, during a period of intense palaeontological exploration and frenzy, which is known as The Bone Wars.
