Introduction




What are dinosaurs?




Dinosaurs are a group of reptiles that have lived on Earth for about 245 million years. The word "dinosaur" comes from the Greek words "deinos" (meaning "fearfully great") and "sauros" (meaning "lizard"). Dinosaurs are different from other reptiles because they have a hole in their hip socket, which allowed them to walk upright. Dinosaurs belong to a larger group of animals called archosaurs, which also includes crocodiles, pterosaurs (flying reptiles), and birds. In fact, birds are considered to be living dinosaurs because they share a common ancestor with non-avian dinosaurs.


How many kinds of dinosaurs are there?




Scientists have identified thousands of individual dinosaur species, which can be roughly assigned to 15 major families. These families include ankylosaurs (armored dinosaurs), ceratopsians (horned, frilled dinosaurs), ornithomimids (bird-like dinosaurs), sauropods (long-necked, plant-eating dinosaurs), theropods (meat-eating dinosaurs), and many more. You can see a list of some of the most popular dinosaur types . Dinosaurs varied greatly in size, shape, color, and features. Some were as small as a chicken, while others were as big as a bus. Some had feathers, horns, spikes, crests, or frills. Some walked on two legs, while others walked on four.


When and where did dinosaurs live?




Dinosaurs lived on all the continents, including Antarctica. They first appeared during the Triassic Period (about 250 to 200 million years ago), when the Earth was a single landmass called Pangaea. As Pangaea broke apart into smaller continents, dinosaurs evolved into different forms to adapt to their changing environments. Dinosaurs reached their peak diversity and abundance during the Jurassic Period (about 200 to 145 million years ago) and the Cretaceous Period (about 145 to 66 million years ago). These two periods are known as the Age of Dinosaurs.
