Dinosaurs

Dinosaurs are a group of reptiles with a wide variety of body forms and diets. Familiar extinct forms include two-legged predators, horned plant-eaters and long-necked sauropods. Skeletons, footprints and other fossils help researchers study how they moved, fed and grew. The prehistoric non-avian dinosaurs were distinct from pterosaurs and marine reptiles, despite often appearing together in popular depictions. Evidence supports some reconstructions more securely than others.
