The First Vertebrates: Oceans of the Paleozoic Eraby Thom Holmes
Vertebrates are the most familiar of all animals on Earth, because humans are one of the 45,000 species of living vertebrates. The rise of the first vertebrates is synonymous with the Paleozoic Era, a time of increasing ecological complexity as the first explosion of life occurred in the seas. The First Vertebrates examines the dramatic rise of vertebrate life in the Paleozoic seas. This fully illustrated volume traces the development of early fish, including jawless fish, fish with jaws and teeth, early sharks, and bony fish-the ancestors of most present-day fish species.
The Prehistoric Earth is a comprehensive series devoted to dinosaurs and other fascinating prehistoric creatures, including mammals, birds, flying reptiles, fish and other ocean life, and human ancestors. The wide variety of life-forms detailed in this series will intrigue student researchers. Each title highlights fundamental principles of scientific inquiry and provides insight into the work of scientists. Striking full-color photographs and illustrations bring to life the secrets of the ancient past of the Earth.
