Book Description
*Includes pictures *Includes a bibliography for further reading Scientists have long attempted to understand Earth's past, and in service to that effort, they have divided the world's history into eons, eras, periods, epochs and ages. For example, the current eon is called the Phanerozoic, which means "visible life." This is the eon in which multi-cellular life has evolved and thrived. Before this, life was microscopic (single cell).The Phanerozoic eon is divided into 3 eras - Paleozoic ("old life"), Mesozoic ("middle life") and Cenozoic ("new life"). From there, the Mesozoic era is divided into 3 periods - Triassic, Jurassic and Cretaceous. Before the Triassic, primitive life had built up in the oceans and seas, and some lifeforms finally had crawled onto land during the Paleozoic era. With that, life had become well established, but then came the Permian-Triassic mass extinction, the worst extinction event in the history of the planet. At the end of the Triassic, another extinction event cleared the way for dinosaurs to become the dominant set of species in the Jurassic. Though the Triassic does not have as interesting a list of creatures as those in the Jurassic and Cretaceous, such as Tyrannosaurus rex, Stegosaurus, Pterodactyls, Brontosaurus, and the like, the life which reclaimed the Earth and then thrived during this period was no less important. Life during the Triassic spent nearly 60% of its time recovering from the Permian-Triassic extinction event, roughly 30 million years. What had been built up was then slammed by nature, effectively clearing the board once more for new species to take over. The Triassic Period: The History and Legacy of the Geologic Era that Witnessed the Rise of Dinosaurs looks at the development of the era, the extinction events that preceded it, and how dinosaurs began to evolve in the Late Triassic. Along with pictures depicting important people, places, and events, you will learn about the Triassic Period like never before.

Book Description
Around 210 million years ago, life on Earth experienced sweeping changes. Many archaic reptiles and mammalian predecessors became extinct and were replaced by dinosaurs, pterosaurs, crocodiles, turtles, mammals, and essentially all of the major modern vertebrate groups except the birds. This period of change, which took place over a period of approximately five to ten million years, ushered in the beginning of the 'Age of Dinosaurs,' a period that lasted 160 million years to the end of the Cretaceous 65 million years ago. In the past decade, paleontologists have come to know a great deal more about this crucial interval of time. New discoveries, ideas, and insights from scientists in many related- disciplines have created new paradigms about the beginning of the 'Age of Dinosaurs.' What were the animals that preceded the dinosaurs like? How did the dinosaurs originate, and what do we know of their early history? Was their ascent tied to evolutionary innovations, global climatic and ecological changes, or just chance factors? How do paleontologists decide about the evidence preserved in the fossil record, and what areas now require major thought and reevaluation? In this book, 31 specialists in the paleontology of this era consider these and other questions related to Late Triassic and Early Jurassic times - the beginning of the 'Age of Dinosaurs,' its fauna, flora, climate, stratigraphic relationships, and major evolutionary changes. The book is divided into sections on background, Late Triassic taxa and faunas, changes across the boundary, Early Jurassic taxa and faunas, and major macroevolutionary patterns. This comprehensive volume is richly illustrated and is intended for students and professionals in the areas of paleontology, evolutionary biology, geology, and vertebrate zoology. Introductory and summary chapters are provided to acquaint the non-specialist with the issues and the setting of this interval of time in which the ancestral components of the modem fauna, as well as the Dinosauria, first appeared to rule the Earth.

Book Description
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.
