The most authoritative illustrated book on flying reptiles availableFor 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 publishedFeatures some 200 illustrations, including original paintings by the authorCovers every known species and major group of pterosaursDescribes pterosaur anatomy, ecology, behaviors, diversity, and moreEncourages further study with 500 references to primary pterosaur literature

A marvelously illustrated look at everything we now know about the fearsome king of the dinosaursTyrannosaurus rex is the world’s favorite dinosaur, adored by the public and the subject of intense study and debate by paleontologists. This stunningly illustrated book brings together everything we have learned about T. rex—the “King of the Tyrant Lizards”—since it was first given its famous name in 1905. It presents these creatures as science knows them rather than the version portrayed in movies, revealing them to be dramatically different, and far more amazing, than ever imagined. With numerous original paintings and diagrams by the author, King Tyrant draws on the latest discoveries to offer a modern understanding of Tyrannosaurus, pulling back the curtain of media hype that often obscures these extraordinary extinct animals while cementing their reputation as the most formidable carnivores of the Mesozoic.Features more than 150 breathtaking illustrations, photos, and diagramsCovers everything from the research history of T. rex to their anatomy, physiology, biomechanics, behavior, and extinctionReveals how the Tyrannosaurus known to science is characterized as much by radical changes in body form throughout its growth as its enormous size and powerful jawsDiscloses details about their lifestyles and behavior evidenced from fossils, from violent face-biting between rivals to their capacity to literally pull the heads off Triceratops carcassesGets to the bottom of the many controversies surrounding T. rex, such as: Was there really more than one species of Tyrannosaurus? Did they live and hunt in groups? How fast could they run and how hard could they bite? Can we truly distinguish males from females?Discusses T. rex in popular culture, showing how our love for this dinosaur has both helped and hindered research
