Book Synopsis Triassic Life on Land by : Hans-Dieter Sues

Download or read book Triassic Life on Land written by Hans-Dieter Sues. This book was released on 2010-04-28. 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.

Book Synopsis Global Events and Event Stratigraphy in the Phanerozoic by : Otto H. Walliser

Download or read book Global Events and Event Stratigraphy in the Phanerozoic written by Otto H. Walliser. This book was released on 2012-12-06. Available in PDF, EPUB and Kindle. Book excerpt: The existence of rapid and even catastrophic turnovers within the Phanerozoic ecosystems has been discussed controversially for more than 170 years. Since 1980 this discussion has become even more intensive after the hypothesis of Alvarez, explaining the end-Cretaceous mass extinction as the result of a huge asteroid impact on the Earth. This theory stimulated several thousand papers and is still controversial. The international research programme on "Global Biological Events in Earth History" attempts to bring the discussion back to the facts by using multidisciplinary investigations of the major Phanerozoic events. The results of an international group of experts are presented giving a wealth of information and a thorough discussion of the causes of the various global events.

Book Synopsis The Beginning of the Age of Dinosaurs by : Kevin Padian

Download or read book The Beginning of the Age of Dinosaurs written by Kevin Padian. This book was released on 1988-09-30. 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.
