Book excerpt: *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.

Download or read book The Beginning of the Age of Dinosaurs written by Kevin Padian and published by Cambridge University Press. This book was released on 1988-09-30 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: *Includes pictures *Includes a bibliography for further reading The early history of our planet covers such vast stretches of time that years, centuries and even millennia become virtually meaningless. Instead paleontologists and scientists who study geochronology divide time into periods and eras. The current view of science is that planet Earth is around 4.6 billion years old. The first four billion years of its development are known as the Precambrian period. For the first billion years or so, there was no life in Earth. Then the first single-celled life-forms, early bacteria and algae, began to emerge. We don't know where they came from or even if they originated on this planet at all. This gradual development continued until around four billion years ago when suddenly (in geological terms!) more complex forms of life began to emerge. Scientists call this time of an explosion of new forms of life the Paleozoic Era and it stretched from around 541 to 250 million years ago (Mya). First of all, in the oceans and then on land, new creatures and plants began to appear in bewildering variety. By the end of this period, life on Earth had exploded into a myriad of complex forms that filled virtually every habitat and niche available in the seas and on the planet's only continent, Pangea. Then a mysterious event that became known to early paleontologists as "The Great Dying" wiped out more than 95% of all life on Earth. No-one is entirely certain what caused this, but the effect of this cataclysm was as if someone had pressed a great, cosmic "reset" button and it took thirty million years for the development of life on Earth to start again. The next period of Earth's history is known as the Mesozoic Era, from about 252 to 66 Mya. This era is further divided into three periods, the Triassic, Jurassic and Cretaceous. During this era, one type of life came to dominate the planet more completely and for a longer period than had been seen before or since; this was the Age of Reptiles. Beginning in the Triassic but especially in the Jurassic period, reptiles came to dominate the oceans, the land and even the skies. There has never been anything else quite like this period in terms of the success of a particular type of creature. For almost two hundred million years, reptiles were the only significant creatures on Earth. They were so successful and so diverse that they evolved to take advantage of every available habitat and no other type of large creature had a chance to develop. To put the 200 million years of reptile dominance in perspective, the entire span of recorded human history, the time since people advanced from tribes of primitive, nomadic hunter-gatherers into recognizable societies, covers less than 6,000 years. To put this in context, if the entire history of the planet were to be laid out on the length of a football field, the period of dominance of the age of reptiles would not begin until the five-yard line and would stretch for twelve feet. All of human history would occupy a tiny strip at the end of the field, less than the width of a human hair. It was during the Jurassic period that reptiles began rule the Earth and some of the best-known prehistoric creatures first emerged. The Jurassic Period: The History and Legacy of the Geologic Era Most Associated with Dinosaurs looks at the development of the era, the extinction events that preceded it, and how life began to evolve during it. Along with pictures depicting important people, places, and events, you will learn about the Jurassic Period like never before.

Download or read book Dinosaurs and Other Prehistoric Life written by DK and published by Penguin. This book was released on 2021-10-12 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive e-guide to dinosaurs and prehistoric animals and the world they inhabited millions of years ago. Includes more than 700 full-color illustrations, this definitive e-guide paints a vivid portrait of extraordinary dinosaurs and prehistoric animals, and the ecosystems they lived in millions of years ago. This e-guide features authoritative text, crystal-clear illustrations, and a straightforward approach to revealing the fascinating lives and habitats of dinosaurs, pterosaurs, marine reptiles, and prehistoric beasts. The introductory section explains classification systems, geological timelines, the evolution of the dinosaurs, and how fossils form and are discovered by paleontologists. For ease of reference, the main body of the ebook is divided into three sections: the Precambrian and Paleozoic eras, when animals first began evolving; the Mesozoic era, which saw the flourishing and eventual extinction of the dinosaurs; and the Cenozoic era, when giant mammals walked the Earth. Each section is broken down into its geological time periods, and, within these, the species are organized according to habitat--whether they lived on land, in the water, or in the air. There are detailed profiles of 200 dinosaurs and other ancestors of modern animals. Each entry combines a precise, jargon-free description with full-color illustrations, skeletons, and replica models, annotated to showcase the unique features of the species. Maps show where each animal's fossils have been found, and many profiles are supported by photographs to show actual excavation sites.

Download or read book Triassic Life on Land written by Hans-Dieter Sues and published by Columbia University Press. This book was released on 2010-04-28 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Triassic period is generally viewed as the beginning of the Age of Dinosaurs. For paleontologists, however, it also marks the rise of the world's first modern land ecosystems. Over the past three decades, extensive, worldwide fieldwork has led to the discovery of many new species of Triassic animals and plants, suggesting that faunal and floral changes already began in the Middle Triassic and were more protracted than previously thought. The Late Triassic is a pivotal time in the evolution of life on land, with many of the major groups of present-day vertebrates and insects first appearing in the fossil record. This book provides the first detailed overview of life on land during the Triassic period for advanced students and researchers. Noted vertebrate paleontologists Hans-Dieter Sues and Nicholas C. Fraser also review the biotic changes of this period and their possible causes.
