20 Interesting Facts About Dinosaurs

Dinosaurs are a group of reptiles that is no longer found, and only fossils remain for their study. They lived on Earth during the Mesozoic era (Triassic, Jurassic, and Cretaceous), about 230 million to 65 million years ago. While humans have been around for only two million years.
