Hunting for fossils with a preeminent guide and teacher Michael Novacek, a world-renowned paleontologist who has discovered important fossils on virtually every continent, is an authority on patterns of evolution and on the relationships among extinct and extant organisms. Time Traveler is his captivating account of how his boyhood enthusiasm for dinosaurs became a lifelong commitment to vanguard science. He takes us with him as he discovers fossils in his own backyard in Los Angeles, then goes looking for them in the high Andes, the black volcanic mountains of Yemen, and the incredibly rich fossil badlands of the Gobi desert. Wherever Novacek goes he searches for still undiscovered evidence of what life was like on Earth millions of years ago. Along the way he has almost drowned, been stung by deadly scorpions, been held at gunpoint by a renegade army, and nearly choked in raging dust storms. Fieldwork is very demanding in a host of unusual, dramatic, sometimes hilarious ways, and Novacek writes of its alluring perils with affection and discernment. But Time Traveler also makes sense of many complex themes - about dinosaur evolution, continental drift, mass extinctions, new methods for understanding ancient environments, and the evolutionary secrets of DNA in fossil organisms. It is also an enthralling adventure story.

Today we are going to embark on a journey back to an age that began before the dinosaurs walked the earth. The age I am referring to was an incredible age with incredible creatures. These ancient animals lived nearly 300 million years ago and thrived for about 50 million years. We humans have only been around for about 60,000 years and we have only been using computers for about 75 years. The ancient animals of this age mysteriously became extinct and disappeared from our earth, but left their fossilized remains behind. Fossils have been discovered constantly in human history; the Chinese thought they were dragon bones and Europeans thought they were the bones of biblical monsters. Luckily, the scientific study of ancient animals began in between 1815-1824 with the discovery of an Iguanodon fossil. Since then ancient animals and dinosaurs have been discovered all over the world. Their immense size, strange shapes, and wonderful natures make them inherently worthy of interest. The study of ancient animals requires depth of imagination, analytical skills, and thought. The many unanswered questions about their lives, behavior, and disappearance provoke the curious to seek answers and ask even more questions. I hope this book fuels your imagination and makes you want to learn even more about dinosaurs and the ancient animals which preceded them. I hope you learn to appreciate the value of your study and that you bring a spirit of openness and wonder on your journey back to an ancient age that began before the age of the dinosaurs.

Today we are going to embark on a journey back to the age of the dinosaurs. The dinosaurs are some of the most incredible animals that ever lived on our planet. They lived nearly 200 million years ago and thrived for about 165 million years. We humans have only been around for about 60,000 years and we have only been using computers for about 75 years. The dinosaurs mysteriously became extinct and disappeared from our earth, but left their fossilized remains behind.

I hope this book fuels your imagination and makes you want to learn even more about dinosaurs. I hope you learn to appreciate the value of the dinosaurs and that you bring a spirit of openness and wonder on your journey back to the age of the dinosaurs. The animal we are going to study today is closely related to the dinosaurs. Its name is Tylosaurus. It was a very large animal that lived in the oceans during the age of the dinosaurs. We are going to learn about what it looked like, how it behaved, and explore its environment it lived in. We know what we know about the dinosaurs from a variety of sources including fossils, biology, and other scientific disciplines. Fossils are the ancient remains of the dinosaurs, the most familiar being their bones. Biological science is the study of life in general and many scientists compare the dinosaurs to modern day animals to support their theories. Before a talk about dinosaurs can take place it is important that we discuss the theory of evolution. Evolutionary theory supposes that all the animals we know and see today are the direct descendants of animals that existed millions of years ago. The dinosaurs and other creatures that existed millions of years ago either died out or gradually changed into different animals. For instance, birds are considered to be surviving dinosaurs because their ancestors survived the dinosaur extinction event (we will discuss this later). Remember that any time you see an * next to the name of a dinosaur, it means that a book has been written about this dinosaur in the Dinosaur Books for Young Readers series. Any word written in bold is an important scientific term which is defined in-text. Italics are used to denote the first time a dinosaur’s name is mentioned in the book.

260 million years ago, life on Earth suffered wave after wave of cataclysmic extinctions, with the worst--the end-Permian extinction--wiping out nearly every species on the planet. This book delves into the mystery behind these extinctions and sheds light on the fateful role the primeval supercontinent, known as Pangea, may have played in causing these global catastrophes. Drawing on the latest discoveries as well as his own field expeditions to remote corners of the world, Paul Wignall reveals what scientists are only now beginning to understand about the most prolonged period of environmental crisis in Earth's history. He describes how a series of unprecedented extinction events swept across the planet in a span of eighty million years, rapidly killing marine and terrestrial life on a scale more devastating than the dinosaur extinctions that would come later. Wignall shows how these extinctions--some of which have only recently been discovered--all coincided with gigantic volcanic eruptions of flood basalt lavas that occurred when the world's landmasses were united into a single vast expanse. Unraveling one of the great enigmas of ancient Earth, this book also explains how the splitting apart of Pangea into the continents we know today ushered in a new age of vibrant and more resilient life on our planet.--Adapted from book jacket.

This study identifies the fall of dinosaurs as the factor that allowed mammals to evolve into the dominant tetrapod form. It refutes the single-cause impact theory for dinosaur extinction and demonstrates that multiple factors--massive volcanic eruptions, loss of shallow seas, and extraterrestrial impact--likely led to their demise. While their avian relatives ultimately survived and thrived, terrestrial dinosaurs did not. Taking their place as the dominant land and sea tetrapods were mammals, whose radiation was explosive following nonavian dinosaur extinction. The author argues that because of dinosaurs, Mesozoic mammals changed relatively slowly for 145 million years compared to the prodigious Cenozoic radiation that followed. Finally out from under the shadow of the giant reptiles, Cenozoic mammals evolved into the forms we recognize today in a mere ten million years after dinosaur extinction.
