Suppose you found some eggs lying on the ground. Now suppose that some little creatures with scales hatched out of them. What kind of animal would they be?
Could they be fish? Fish have scaly skin, but fish eggs do not have hard shells. Besides, most fish lay their eggs in water. So they could not be fish.
Could they be birds? Birds lay eggs, too. But birds don’t have such scaly skin. So they could not be birds.
They must be reptiles. Only reptiles have scaly skin and lay their eggs on land. Alligators, crocodiles, lizards, snakes, turtles, and tuataras are all reptiles.
