Dinosaurs are a large group of now extinct reptiles in the Dinosauria clade. They were the dominate land vertebrates on Earth for more than 165 million years. Their domination of Earth was abruptly ended about 66 million years ago due to a massive extinction event. The prevailing theory of what caused this massive extinction event is an asteroid impact. Scientists believe an asteroid six to nine miles wide struct Earth in the Yucatan Peninsula 66 million years ago. This theory is backed by the Chicxulub crater, which proves a massive asteroid struck Earth around 66 million years. The extinction of the dinosaurs paved the road for mammals to rise, which would lead to the rise of humanity.
Paleontologists aren’t sure how many dinosaurs species existed, they can only tell by what fossil evidence they have discovered. To date, around 700 valid dinosaur species have been discovered, with new ones found every year. Dinosaur species are divided into three major groups and those groups are sauropods, theropods, and ornithischians. Sauropods are herbivorous dinosaur species and include the Apatosaurus and the Brontosaurus. Theropods are predominantly carnivorous dinosaur species and include the Allosaurus and Tyrannosaurus rex. Ornithischians are mostly herbivorous dinosaur species and included the Ankylosaurs and the Stegosaurus.
