Hundreds of millions of years ago, when the continents had formed and long before human beings had even begun to evolve, it was dinosaurs that ruled the earth. Dinosaurs - which comes for the Greek for ‘terrible lizard’ - were a group of reptiles that dominated this very planet we stand on for more than 160 million years. Then, around 65 million years ago, more than 50% of the world's species became extinct - dinosaurs included. Scientists are still at a loss as to why and how this mass extinction came to be. So, exactly what happened to the dinosaurs?


1. When Did Dinosaurs First Appear On Earth?

According to Paleontologists, dinosaurs first appeared around 240 million years ago. Throughout their existence, scientists have also identified three different epochs: the Triassic, Jurassic, and Cretaceous Period. Over this period, which is collectively known as the Mesozoic era, the Earth's continents changed from a single supercontinent called Pangea and our planet as we know it today.

Did You Know? Most of the dinosaurs in the movie Jurassic Park were actually from the Cretaceous Period. Although 'Cretaceous Park' doesn't exactly have the same ring to it, does it?
