Characterized by a surge in biodiversity and evolutionary development, the Paleozoic Era ushered in the beginnings of life as we know it. Within these pages, readers will discover the fossil and geologic evidence from this time that reveals a dynamic planet, where new species of plants and animals were constantly emerging and continents were breaking apart and reforming. While many of the species from this era are now extinct and the continents are relatively stable, remnants of this era still continue to shed much-needed light on the conditions of Earth, both past and present.

Dinosaurs have captured the imaginations of children and adults alike since the first fossil discoveries mapped them onto our general body of knowledge. This book journeys to an era long before humans, where dinosaurs were once masters of land, sky, and sea. In addition to accounts of significant dinosaur species and their extinction, readers will learn about the major life forms, both plant and animal, alongside whom dinosaurs dwelled, as well as the geographical and environmental factors that affected their subsistence.
