Book Description
Dinosaurs were a group of reptiles that lived on Earth millions of years ago. They were some of the largest animals to ever roam the planet, with some species growing to be as tall as a two-story building. Dinosaurs first appeared during the Mesozoic Era, which is sometimes referred to as the "Age of Reptiles." This era lasted from about 252 million years ago to 66 million years ago and was divided into three periods: the Triassic, Jurassic, and Cretaceous periods. During the Triassic period, the earliest dinosaurs evolved from smaller reptiles. These early dinosaurs were not very large, and they were not the dominant animals on Earth at the time. However, during the Jurassic and Cretaceous periods, dinosaurs became much larger and more diverse.

Book Description
Travel back to the time when the mighty dinosaurs ruled the earth. The Age of Dinosaurs began about 250 million years ago. In the beginning they were quite small but over time they evolved into the varied and fascinating creatures that captivate our imaginations today. What we know about dinosaurs is evolving, too! We've learned that some dinosaurs were good parents, that dinosaurs could grow new teeth when old ones fell out, and that most dinosaurs walked on two legs. We've even discovered that birds are modern relatives of dinosaurs!

Book Description
What can long-dead dinosaurs teach us about our future? Plenty, according to paleontologist Kenneth Lacovara, who has discovered some of the largest creatures to ever walk the Earth. By tapping into the ubiquitous wonder that dinosaurs inspire, Lacovara weaves together the stories of our geological awakening, of humanity’s epic struggle to understand the nature of deep time, the meaning of fossils, and our own place on the vast and bountiful tree of life. Go on a journey––back to when dinosaurs ruled the Earth––to discover how dinosaurs achieved feats unparalleled by any other group of animals. Learn the secrets of how paleontologists find fossils, and explore quirky, but profound questions, such as: Is a penguin a dinosaur? And, how are the tiny arms of T. rex the key to its power and ferocity? In this revealing book, Lacovara offers the latest ideas about the shocking and calamitous death of the dinosaurs and ties their vulnerabilities to our own. Why Dinosaurs Matter is compelling and engaging—a great reminder that our place on this planet is both precarious and potentially fleeting. “As we move into an uncertain environmental future, it has never been more important to understand the past.”

Book Description
For 65 million years dinosaurs ruled the Earth-until a deadly asteroid forced their extinction. But what accounts for the incredible longevity of dinosaurs? A renowned scientist now provides a startling explanation that is rewriting the history of the Age of Dinosaurs. Dinosaurs were pretty amazing creatures-real-life monsters that have the power to fascinate us. And their fiery Hollywood ending only serves to make the story that much more dramatic. But fossil evidence demonstrates that dinosaurs survived several mass extinctions, and were seemingly unaffected by catastrophes that decimated most other life on Earth. What could explain their uncanny ability to endure through the ages? Biologist and earth scientist Peter Ward now accounts for the remarkable indestructibility of dinosaurs by connecting their unusual respiration system with their ability to adapt to Earth's changing environment-a system that was ultimately bequeathed to their descendants, birds. By tracing the evolutionary path back through time and carefully connecting the dots from birds to dinosaurs, Ward describes the unique form of breathing shared by these two distant relatives and demonstrates how this simple but remarkable characteristic provides the elusive explanation to a question that has thus far stumped scientists. Nothing short of revolutionary in its bold presentation of an astonishing theory, Out of Thin Air is a story of science at the edge of discovery. Ward is an outstanding guide to the process of scientific detection. Audacious and innovative in his thinking, meticulous and thoroughly detailed in his research, only a scientist of his caliber is capable of telling this surprising story.
