Masterfully tying together history, science, and human drama, The Lost Dinosaurs of Egypt is the gripping account of two of the 20th century's great expeditions of discovery. In 1911 a German paleontologist found the remains of four entirely new dinosaurs in the Egyptian desert, but in a single night, all of his work was destroyed. Eighty-nine years later, an American grad student leads an expedition to unearth Stromer's dinosaur graveyard, and in doing so, he stuns the scientific world.

From the author of Apocalyptic Planet, an unsparing, vivid, revelatory travelogue through prehistory that traces the arrival of the First People in North America 20,000 years ago and the artifacts that enable us to imagine their lives and fates. This book upends our notions of where these people came from and who they were.

Daniel Loxton and Donald R. Prothero have written an entertaining, educational, and definitive text on cryptids, presenting the arguments both for and against their existence and systematically challenging the pseudoscience that perpetuates their myths. After examining the nature of science and pseudoscience and their relation to cryptozoology, Loxton and Prothero take on Bigfoot; the Yeti, or Abominable Snowman, and its cross-cultural incarnations; the Loch Ness monster and its highly publicized sightings; the evolution of the Great Sea Serpent; and more.

In this work on a subject too often dismissed as paranormal or disreputable, Jeffrey Meldrum gives us the first book on Sasquatch to be written by a scientist with impeccable academic credentials. He gives an objective look at the facts in a field mined with hoaxes and sensationalism. Meldrum reports on the work of a team of experts from a wide variety of fields who were assembled to examine the evidence for a large, yet undiscovered, North American primate. He reviews the long history of this mystery and explains all the scientific pros and cons in a clear and accessible style.

In movies, in novels, in comic strips, and on television, we've all seen dinosaurs - or at least somebody's educated guess of what they would look like. But what if it were possible to build, or grow, a real dinosaur without finding ancient DNA? Jack Horner, the scientist who advised Steven Spielberg on the blockbuster film Jurassic Park and a pioneer in bringing paleontology into the 21st century, teams up with the editor of the New York Times's Science Times section to reveal exactly what's in store.

In just the past twenty years, we have learned more about dinosaurs than we did in the previous two centuries. This book describes the extraordinary advances in palaeontology that are beginning to solve many of the mysteries surrounding these marvelous prehistoric creatures, from their ways of communicating to their mating habits, the colour of their skin, their migration patterns and extinction. How did dinosaurs rear their young? What did they eat? What did T. rex actually do with those tiny arms?

Revised, updated, and expanded with the latest interpretations and fossil discoveries, the second edition of Oceans of Kansas adds new twists to the fascinating story of the vast inland sea that engulfed central North America during the Age of Dinosaurs. Giant sharks, marine reptiles called mosasaurs, pteranodons, and birds with teeth all flourished in and around these shallow waters. Their abundant and well-preserved remains were sources of great excitement in the scientific community when first discovered in the 1860s and continue to yield exciting discoveries 150 years later.

Who were the first humans to inhabit North America? According to the now familiar story, mammal hunters entered the continent some 12,000 years ago via a land bridge that spanned the Bering Sea. The presence of these early New World people was established by distinctive stone tools belonging to the Clovis culture. But are the Clovis tools Asian in origin? Drawing from original archaeological analysis, paleoclimatic research, and genetic studies, noted archaeologists Dennis J. Stanford and Bruce A. Bradley challenge the old narrative.

This volume, aimed at the general audience, presents life and times of the amazing animals that inhabited Earth more than 500 million years ago. The Cambrian Period was a critical time in Earth's history. During this immense span of time nearly every modern group of animals appeared. Although life had been around for more than 2 million millennia, Cambrian rocks preserve the record of the first appearance of complex animals with eyes, protective skeletons, antennae, and complex ecologies.

Over the last century, the search for human ancestors has spanned four continents and resulted in the discovery of hundreds of fossils. While most of these discoveries live quietly in museums, there are a few that have become world-renowned celebrity personas. In Seven Skeletons, historian of science Lydia Pyne explores how seven such famous fossils of our ancestors have the social cachet they enjoy today.

Hace unos 4.000 millones de años apareció la vida en la Tierra. ¿Cuál es la historia de su evolución? ¿Era inevitable la vida? ¿Y la raza humana? ¿La habría habitado algún otro ser inteligente, si no hubiera habido humanos? ¿Qué patrones usa el mecanismo evolutivo? ¿La evolución avanza hacia adelante como una flecha?

Although we usually think of technology as something unique to modern times, our ancestors began to create the first technologies millions of years ago in the form of prehistoric tools and weapons. Over time, eight key technologies gradually freed us from the limitations of our animal origins.

Dinosaurs. No other class of animals captures the hearts of both children and adults alike. Paleontologist Armin Schmitt brings us a firsthand account of the latest research on dinosaurs and their lives millions of years ago, including his spectacular global excavations and fascinating discoveries in the field. With the help of cutting-edge technology and unbelievable new finds, the age-old tale of the dinosaurs is now revitalized for the very first time, complete with astonishing illustrations by Ben Rennen that help us imagine dinosaurs like never before.

Books about the origins of humanity dominate bestseller lists, while national newspapers present breathless accounts of new archaeological findings and speculate about what those findings tell us about our earliest ancestors. We are obsessed with prehistory—and, in this respect, our current era is no different from any other in the last three hundred years. In this coruscating work, acclaimed historian Stefanos Geroulanos demonstrates how claims about the earliest humans not only shaped Western intellectual culture, but gave rise to our modern world.

Ian Tattersall, a highly esteemed figure in the fields of anthropology, archaeology, and paleontology, leads a fascinating tour of the history of life and the evolution of human beings. Starting at the very beginning, Tattersall examines patterns of change in the biosphere over time, and the correlations of biological events with physical changes in the Earth's environment.

Griffins, cyclopes, monsters, and giants - these fabulous creatures of classical mythology continue to live in the modern imagination through the vivid accounts that have come down to us from the ancient Greeks and Romans. But what if these beings were more than merely fictions? Through careful research and meticulous documentation, Adrienne Mayor convincingly shows that many of the giants and monsters of myth did have a basis in fact - in the enormous bones of long-extinct species that were once abundant in the lands of the Greeks and Romans.

In Origins, Frank H. T. Rhodes explores the origin and evolution of living things, the changing environments in which they have developed, and the challenges we now face on an increasingly crowded and polluted planet. Rhodes argues that the future well-being of our burgeoning population depends in no small part on our understanding of life's past, its long and slow development, and its intricate interdependencies.

The fascinating group of animals called dinosaurs became extinct some 65 million years ago (except for their feathered descendants). In their place evolved an enormous variety of land creatures, especially mammals, which in their way were every bit as remarkable as their Mesozoic cousins. The Age of Mammals, the Cenozoic Era, has never had its Jurassic Park, but it was an amazing time in earth's history, populated by a wonderful assortment of bizarre animals. The rapid evolution of thousands of species of mammals brought forth many incredible creatures—including our own ancestors.

Adored by children and adults alike, tyrannosaurus is the most famous dinosaur in the world, one that pops up again and again in pop culture, often battling other beasts such as King Kong, triceratops, or velociraptors in Jurassic Park. But despite the hype, tyrannosaurus and the other tyrannosaurs are fascinating animals in their own right and are among the best-studied of all dinosaurs.

Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a devastating cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? In Dark Matter and the Dinosaurs, Lisa Randall proposes it was a comet that was dislodged from its orbit as the solar system passed through a disk of dark matter embedded in the Milky Way. In a sense it might have been dark matter that killed the dinosaurs.
