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

Pterosaurs, the first vertebrates to evolve powered flight, are undergoing a long-running scientific renaissance that has seen sustained, and even elevated interest, from several generations of palaeontologists. These incredible reptiles are known from every continent, flew the Mesozoic skies for at least 160 million years, diversified into more than a dozen major clades and well over 100 species, and included the largest flying animals of all time. This volume brings together leading pterosaur researchers from around the globe to discuss new and cutting-edge research into various aspects of pterosaur palaeobiology and presents diverse papers to deliver new insights on flying reptile palaeoecology, flight, ontogeny, skeletal and soft-tissue anatomy, temporal and spatial distribution and evolution, as well as revisions of their taxonomy and interrelationships.

A brilliant lyrical exploration of how modern science illuminates what it means to be human, from the award-winning author of The Price of Altruism We no longer think, like the ancient Chinese did, that the world was hatched from an egg, or, like the Maori, that it came from the tearing-apart of a love embrace. The Greeks told of a tempestuous Hera and a cunning Zeus, but we now use genes and natural selection to explain fear and desire, and physics to demystify the workings of the universe. Science is an astounding achievement, but are we really any wiser than the ancients? Has science revealed the secrets of fate and immortality? Has it provided protection from jealousy or love? There are those who believe that science has replaced faith, but must it also be a death knell for mythology? Evolutions brings to life the latest scientific thinking on the birth of the universe and the solar system, the journey from a single cell all the way to our human minds. Reawakening our sense of wonder and terror at the world around us and within us, Oren Harman uses modern science to create new and original mythologies. Here are the earth and the moon presenting a cosmological view of motherhood, a panicking mitochondrion introducing sex and death to the world, the loneliness of consciousness emerging from the memory of an octopus, and the birth of language in evolution summoning humankind’s struggle with truth. Science may not solve our existential puzzles, but like the age-old legends, its magical discoveries can help us continue the never-ending search.

Vertebrate palaeontology is a lively field, with new discoveries reported every week… and not only dinosaurs! This new edition reflects the international scope of vertebrate palaeontology, with a special focus on exciting new finds from China. A key aim is to explain the science. Gone are the days of guesswork. Young researchers use impressive new numerical and imaging methods to explore the tree of life, macroevolution, global change, and functional morphology. The fourth edition is completely revised. The cladistic framework is strengthened, and new functional and developmental spreads are added. Study aids include: key questions, research to be done, and recommendations of further reading and web sites. The book is designed for palaeontology courses in biology and geology departments. It is also aimed at enthusiasts who want to experience the flavour of how the research is done. The book is strongly phylogenetic, and this makes it a source of current data on vertebrate evolution.

Dieses Buch handelt von den faszinierenden und gleichzeitig gefürchtetsten Geschöpfen, die die Natur hervorgebracht hat. Seit jeher haben Menschen Schlangen mit Neugier und Angst, aber auch mit Ehrfurcht und Abscheu betrachtet. Schlangen bedeuten extreme Gefahr, Ungewissheit, jedoch auch wertvolle Nahrung. In vielen Kulturen symbolisieren sie besonders Positives: Fruchtbarkeit, Verjüngung, auch Frieden oder Heilung. Das Buch ist in drei Teile gegliedert. Im ersten geht es um die Klassifikation und die allgemeine Biologie von Schlangen. Teil II gibt einen Überblick über alle wichtigen systematischen Gruppen der Serpentes. Im dritten und abschliessenden Teil sind Evolution und Biogeographie von Schlangen das Thema. Harry W. Greene und die Photographen Michael und Patricia Fogden führen Wissenschaft und Kunst zusammen, um dem Leser die Schönheit und Faszination dieser Tiere zu vermitteln. Herausgekommen ist so eine einzigartige Lektüre für interessierte Laien sowie für Biologen, Herpetologen und Terrarianer.

Here is the first complete portrait of the legendary flying dragons of deep time-the pterosaurs-designed for non-specialists, yet founded on the real science of these bizarre creatures. Presented lucidly and accessibly by one of the world's leading experts, David Unwin's book is built on a mountain of new fossil discoveries and the latest research. About 220 millions years ago, a group of reptiles took to the Earth's vast and open skies. No longer tethered to the ground, the earliest pterosaurs evolved into a multitude of diverse forms, spread around the globe, and ruled the skies until they went extinct along with the dinosaurs about 65 millions years ago, rarely leaving fossils as a record of their existence. What they did leave was a mystery for paleontologists to solve; an enigma so difficult to crack that it took centuries of false starts and missteps before the path to a true understanding of pterosaurs was uncovered. Now, an understanding of the fundamental nature of these strange creatures is finally possible. In the last 15 years, stunning new fossil finds and significant advances in technology have led to a breakthrough in our knowledge of pterosaurs. New fossils of the earliest species were discovered in Italy, a remarkably well-preserved and complete wing was found in Central Asia, and, most extraordinarily, a pterosaur embryo inside an egg was unearthed in China. CAT scanning has let researchers glimpse inside pterosaur skulls and construct three-dimensional images of their bodies from crushed bones, and modern techniques for analyzing relationships between species have revealed surprising insights into the evolution of the group. Drawing on these and other advances, DavidUnwin, caretaker of Archaeopteryx and curator at the Museum of Natural History in Berlin, paints pterosaurs and their world more vividly than has previously been possible. He eloquently reconstructs their biology and behavior. Pterosaurs weren't scaly like dinosaurs, but hairy; most were brightly colored and adorned with remarkable head crests; they were excellent fliers with physiologically sophisticated wings; they walked on all fours; and varied in size from eight inches to forty feet in wingspan. He shows how they lived their lives, raised their young, and interacted with the different environments of Mesozoic Earth. Then, building on his thorough examination of their anatomy and lifestyle, and using the powerful technique of cladistic analysis, Unwin unravels the evolutionary history of pterosaurs and establishes their place in the one great tree of life. Packed with 95 color and 30 black and white illustrations-including 10 full-page original color paintings that are scientific recreations of different pterosaur species-"The Pterosaurs From Deep Time" takes readers on an wondrous expedition back through the lost world of the Earth's deep past.
