"From the author of Apocalyptic Planet, an unsparing, vivid, revelatory travelogue through prehistory that traces the arrival of the First People in North America twenty thousand years ago and the artifacts that enable us to imagine their lives and fates. Scientists squabble over the locations and dates for human arrival in the New World. The first explorers were few, encampments fleeting. At some point in time, between twenty and forty thousand years ago, sea levels were low enough that a vast land bridge was exposed between Asia and North America. But the land bridge was not the only way across. This book upends our notions of where these people came from and who they were. The unpeopled continent they reached was inhabited by megafauna--mastodons, sloths, mammoths, saber-toothed cats, lions, bison, and bears. The First People were not docile--Paleolithic spear points are still encrusted with the protein of their prey--but they were wildly outnumbered and many were prey to the much larger animals. This is a chronicle of the last millennia of the Ice Age, the gradual oscillations and retreat of glaciers, the clues and traces that document the first encounters of early humans, and the animals whose presence governed the humans' chances for survival"--.

"For 150 million years, the skies didn't belong to birds--they belonged to the pterosaurs. These flying reptiles, which include the pterodactyls, shared the world with the nonavian dinosaurs until their extinction 65 million years ago. Some pterosaurs, such as the giant azhdarchids, were the largest flying animals of all time, with wingspans exceeding thirty feet and standing heights comparable to modern giraffes. This richly illustrated book takes an unprecedented look at these astonishing creatures, presenting the latest findings on their anatomy, ecology, and extinction. Pterosaurs features some 200 stunning illustrations, including original paintings by Mark Witton and photos of rarely seen fossils. After decades of mystery, paleontologists have finally begun to understand how pterosaurs are related to other reptiles, how they functioned as living animals, and, despite dwarfing all other flying animals, how they managed to become airborne. Here you can explore the fossil evidence of pterosaur behavior and ecology, learn about the skeletal and soft-tissue anatomy of pterosaurs, and consider the newest theories about their cryptic origins. This one-of-a-kind book covers the discovery history, paleobiogeography, anatomy, and behaviors of more than 130 species of pterosaur, and also discusses their demise at the end of the Mesozoic; The most comprehensive book on pterosaurs ever published; features some 200 illustrations, including original paintings by the author; covers every known species and major group of pterosaurs; describes pterosaur anatomy, ecology, behaviors, diversity, and more; encourages further study with 500 references to primary pterosaur literature"--.

The author explores modern developments in the field of paleontology, focusing on studies pertaining to dinosaurs and revealing up-to-date information about them. Details the reasons dinosaurs serve as such a source of fascination among the general public and includes anecdotes from the author about his own obsession with the creatures.
