The popular ideals of dinosaurs have many misconceptions, reinforced by films, books, comics, television shows, and even theme parks. Typical errors include: prehistoric humans living with dinosaurs; dinosaurs as monsters that did little else but fight; the portrayal of a kind of "prehistoric world" where all prehistoric animals are shown to exist; dinosaurs as all large; dinosaurs as stupid and slow-moving; dinosaurs as being lizard-like and all scaled (non-feathered) when many theropod dinosaurs such as "Velociraptor" had feathers, and the inclusion of many prehistoric animals (such as "Dimetrodon", pterosaurs, pleisiosaur, ichthyosaurs, and mosasaurs) as dinosaurs. Moreover, dinosaurs did not become extinct due to being generally maladapted or unable to cope with normal climatic change, a view found in many older textbooks.
