In 1980 Nobel Laureate Luis Alvarez announced his theory of the dinosaurs final demise: a gigantic meteorite crashed into the earth and raised a cloud of dust that caused darkness for years, suppressing photosynthesis, which impeded plant growth, and eventually starved the dinosaurs. This idea exploded into common awareness with almost unprecedented speed, and was instantly embraced by the media and the public. Almost without question, it quickly became the hottest scientific "fact". Unfortunately for Alvarez, many in the scientific community did to support this theory, and in fact later research showed the impossibility of such an idea. The Great Dinosaur Extinction Controversy chronicles the fantastic story of how this hypothesis became so widespread, the way it became "common knowledge" - from the pages of Science to The New York Times to Parade Magazine, the controversy it caused, and the ample scientific research that proves the theory wrong. Officer and Page also present an attractive and carefully investigated alternative explanation for the mass extinctions that occurred at the end of the Cretaceous period. Through this account they show the ways that sound science should be performed and the findings transmitted.

The End of the Dinosaurs gives a detailed account of the great mass extinction that rocked the Earth 65 million years ago, and focuses on the discovery of the culprit: the Chicxulub impact crater in Mexico. It recounts the birth of the cosmic hypothesis, the controversy that preceded its acceptance, the search for the crater, its discovery and ongoing exploration, and the effect of the giant impact on the biosphere. Other mass extinctions in the fossil record are reviewed, as is the threat of asteroids and comets to our planet today. The account of the impact and its aftermath is suitable for general readers. The description of the crater geology is in enough detail to interest students of the earth sciences. A detailed index and bibliography are included.

Archaeologist Brandon Thackery and his rival Miles 'Klicks' Jordan fulfill a dinosaur lover's dream with history's first time-travel jaunt to the late Mesozoic. Hoping to solve the extinction mystery, they find Earth's gravity is only half its 21st century value and dinosaurs that behave very strangely. Could the slimey blue creatures from Mars have something to do with both?

The Times Science Book of the Year. A Sunday Times Bestseller. 66 million years ago the dinosaurs were wiped from the face of the earth. Today, Dr. Steve Brusatte, one of the leading scientists of a new generation of dinosaur hunters, armed with cutting edge technology, is piecing together the complete story of how the dinosaurs ruled the earth for 150 million years. The world of the dinosaurs has fascinated on book and screen for decades – from early science fiction classics like The Lost World, to Godzilla terrorizing the streets of Tokyo, and the monsters of Jurassic Park. But what if we got it wrong? In The Rise and Fall of the Dinosaurs, top dinosaur expert Brusatte, tells the real story of how dinosaurs rose to dominate the planet. Using the fossil clues that have been gathered using state of the art technology, Brusatte follows these magnificent creatures from their beginnings in the Early Triassic period, through the Jurassic period to their final days in the Cretaceous and the legacy that they left behind. Along the way, Brusatte introduces us to modern day dinosaur hunters and gives an insight into what it’s like to be a paleontologist. The Rise and Fall of the Dinosaurs is full of thrilling accounts of some of his personal discoveries, including primitive human-sized tyrannosaurs, monstrous carnivores even larger than T. rex, and feathered raptor dinosaurs preserved in lava from China. At a time when Homo sapiens has existed for less than 200,000 years and we are already talking about planetary extinction, The Rise and Fall of the Dinosaurs is a timely reminder of what humans can learn from the magnificent creatures who ruled the earth before us. 'Thrilling . . . the best book on the subject written for the general reader since the 1980s.' - The Sunday Times

*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.

Geared toward a broad variety of students, Dinosaurs: The Textbook offers a concise and lucid presentation of the core biological and geological concepts of dinosaur science. Revised throughout to reflect recent fossil discoveries and the current scientific consensus, this seventh edition details the evolution, phylogeny, and classification of various dinosaur species while modeling the best approach for navigating new and existing research. Spencer G. Lucas takes readers through the major taxonomic groups, including theropods, sauropodomorphs, ornithopods, ceratopsians, pachycephalosaurs, stegosaurs, and ankylosaurs. He also examines the behavior and extinction of the dinosaurs, their biological relationship to birds, and their representation (or misrepresentation) in art, literature, film, and other forms of popular culture. This seventh edition of the leading text for introductory courses on dinosaurs incorporates comprehensive updates based on the latest research. Lucas highlights how dinosaur science is rapidly evolving, exploring how new discoveries, methods, and ideas are expanding the frontiers of knowledge. The book features cutting-edge and scientifically rigorous illustrations by leading paleoartists. It also includes extensive and reader-friendly end-of-chapter summary tools, review questions, a detailed glossary, a dinosaur dictionary, and a comprehensive index.

A paleontologist awakens us to the "extinction event" that human activity is bringing about today The natural world as humans have always known it evolved close to 100 million years ago, with the appearance of flowering plants and pollinating insects during the age of the dinosaurs. Its tremendous history is now in danger of profound, catastrophic disruption. In Terra, a brilliant synthesis of evolutionary biology, paleontology, and modern environmental science, Michael Novacek shows how all three can help us understand and prevent what he (and others) call today's "mass extinction event." Humanity's use of land, our consumption, the pollution we create, and our contributions to global warming are causing this crisis. True, the fossil record of hundreds of millions of years reveals that wild and bounteous nature has always evolved not quietly but thunderously, as species arise, flourish, die off, and are replaced by new species. We learn from paleontology and archaeology that for 50,000 years, human hunting, mining, and agriculture have changed many localities, sometimes irrevocably. But today, Novacek insists, our behavior endangers the entire global ecosystem. And if we disregard—through ignorance, antipathy, or apathy—the theory of evolution that developed with our modern understanding of the Earth's past, we not only impede enlightenment but threaten any practical strategy for our own survival. The evolutionary future of the entire living planet depends on our understanding this.
