Dinosaurs were a group of creatures that roamed on Earth millions of years ago – in the Mesozoic Era. The era was further divided into epochs, also known as periods. These are the Triassic Period, Jurassic Period and Cretaceous
Period. The Triassic Period is marked by the rise of the dinosaur. At
the beginning of the Triassic Period there were only plants but evidence
shows that in the middle of this period, Dinosaurs evolved.
In order to understand this species, paleontologists have studied their fossils. It has been found that dinosaurs can be categorized in two ways – first, by the structure of their hips, and second, by their diet. By studying their hip structure, dinosaurs have been further categorized into two groups – Saurischians and Ornithiscians. Saurischians means, “lizard-hipped” dinosaurs and Ornithischians means, “bird-hipped” dinosaurs. By studying their diet, dinosaurs can be further categorized into three groups – Carnivores, Herbivores and Omnivores. Carnivores ate other animals, Herbivores ate vegetation and Omnivores ate both animals and vegetation.
