Concise detailed review — amply illustrated — of the astonishing creatures that ruled the earth for some 180 million years, with particular emphasis on the tetrapods (four-legged vertebrates that lived during the years of reptilian dominance). Also examines interrelationships between amphibians and reptiles, birds and mammals, and between these creatures and their environments.
