Dinosaurs, Reptiles
In the beginning of the nineteenth century, the first dinosaur fossils gave their appearance, and since then dinosaurs have become a part of the most fertile human imaginations. On the other hand, reptiles are cold-blooded vertebrates with their skin covered in scales rather than hair or feathers. They include crocodiles, alligators, tuatara, lizards, snakes, amphisbaenians and turtles, grouped together as the class Reptilia.
