Dinosaurs>>Dinosaurs Fact and Fiction

 

Did all the dinosaurs live together, and at the same time?

Dinosaur communities were alienated by both time and geography. The age of dinosaurs (the Mesozoic Era) included three successive geologic time periods (the Triassic, Jurassic, and Cretaceous Periods). Dissimilar dinosaurs species lived during each of these three periods. For example, the Jurassic dinosaur Stegosaurus already had been extinct for around 80 million years earlier than the appearance of the Cretaceous dinosaurs Tyrannosaurus.

In fact, the time unraveling Stegosaurus and Tyrannosaurus is greater than the time separating Tyrannosaurus and you. At the beginning of dinosaurs history (the Triassic Period), there was one super continent on Earth (Pangea). Numerous dinosaur types were widespread across it. However, as Pangea broke apart, dinosaurs became scattered across the world on separate continents, and new types of dinosaurs evolved separately in every geographic area.
