Book Description
Birds and dinosaurs have dominated human interest for decades. In this well-supported revolutionary view of the field, critical questions are explored with credible evidence and biological thought. Are birds derived directly from advanced dinosaurs, or are they closely related dinosaur cousins? Did flight originate via the natural "gravity-assisted" trees-down model, or from the improbable “gravity-resisted” ground-up model? Were the earliest birds ground-predators or trunk-climbing gliders? Were dinosaurs hot-blooded with insulating protofeathers, or highly active, cold-blooded reptiles? These are among the questions addressed in this path-breaking book. Current consensus suggests that early birds were earth-bound and flight began on the ground. Reversing that logic, since birds are hot-blooded, by inference so too were dinosaurs, and extraordinarily complex feathers, flight brain and inner ear, evolved before flight in dinosaurs. The iconic early bird Archaeopteryx, despite innumerable flight and arboreal features, is now displayed as an earth-bound predator that could not fly. In reality, we have yet to provide satisfactory explanations for much of the biological origin and early evolution of birds. Among the questions addressed is whether truly feathered dinosaurs are in reality lost or "hidden birds?" The architectural complexity of feathers leads the author to the conclusion that if an animal has evolved extraordinarily complex, aerodynamically-designed feathers, an avian flight hand, flight membranes, and a flight brain, it's a bird. Birds and dinosaurs captivate and enchant the human imagination. These intriguing animals have dominated the field of paleontology and evolution for the past half century, engendering heated debate on avian ancestry, the origin of flight and feathers, and the biology of their fossils. Are birds living dinosaurs? In this series of entertainingly contentious and captivating essays evolutionary biologist Alan Feduccia writes with verve and humor to expose major problems in the field and advocate liberation from the shackles of consensus thinking about birds and dinosaurs. He maintains that the euphoria of paleontologists claiming to have solved the major problems of bird evolution is premature, largely generated by the adoption of a rigid, cult-like methodology, heavily blended with ideology, and excluding many biological and geological principles. He adroitly exposes and elucidates major mistakes in the field and their aftermath. Romancing the Birds and Dinosaurs is a lucid revelation of clarity and synthesis, a fascinating unveiling of the underlying science that has produced the good, but also often appalling fossil research and wild speculation in bird and dinosaur evolution. A must read for anyone interested in this rapidly evolving field, the short, concise and incisive essays provide the reader with access to this complex topic. REVIEWS and WORDS OF PRAISE In this strikingly unconventional and brilliant book, Professor Alan Feduccia presents the current status of the recent controversy about the origin of birds with clarity and vigor. A thought-provoking personal exploration of what the bird fossils represent. ---Sankar Chatterjee, Paul Whitfield Horn Distinguished Professor of Geosciences and Curator of Paleontology, Texas Tech University. Feduccia's book eloquently reminds us that consensus science is to be shied away from especially when it is used to plead special cases against basic scientific principles. The concept of “lost birds” is particularly intriguing as it defines what birds are and how special science obfuscates the simplicity of evolution. ---David A. Burnham, Associate Researcher, University of Kansas Biodiversity Institute and Natural History Museum. Based on a thorough understanding of the empirical evidence, Feduccia presents a convincing account of avian origins from their putative ancestors. ---Walter J. Bock, Professor of Evolutionary Biology, Columbia University and Research Associate, American Museum of Natural History. With candor, clear thinking, humor, and abundant evidence, Alan Feduccia’s Romancing the Birds and Dinosaurs should be mandatory reading for the countless millions who are intrigued by dinosaurs and their relatives, the birds. Feduccia points out the many empirical and logical shortcomings in the stubborn majority view that birds evolved from dinosaurs, an idea now solidly entrenched as dogma in education and popular culture. This new book will be as interesting to those who study human behavior and scientific methods as it will to students of vertebrate evolution. ---David W. Steadman, Curator of Ornithology, Professor of Biology, Florida Museum of Natural History, University of Florida.

Book Description
In 1861, just a few years after the publication of Charles Darwin's On the Origin of Species, a scientist named Hermann von Meyer made an amazing discovery. Hidden in the Bavarian region of Germany was a fossil skeleton so exquisitely preserved that its wings and feathers were as obvious as its reptilian jaws and tail. This transitional creature offered tangible proof of Darwin's theory of evolution. Hailed as the First Bird, Archaeopteryx has remained the subject of heated debates for the last 140 years. Are birds actually living dinosaurs? Where does the fossil record really lead? Did flight originate from the "ground up" or "trees down"? Pat Shipman traces the age-old human desire to soar above the earth and to understand what has come before us. Taking Wing is science as adventure story, told with all the drama by which scientific understanding unfolds.

Book Description
Although consensus exists among researchers that birds evolved from coelurosaurian theropods, paleontologists still debate the identification of the group of coelurosaurians that most closely approaches the common ancestor of birds. The last 20 years witnessed the discovery of a wide array of avian-like theropods that has considerably amplified the anatomical disparity among deinonychosaurians, some of which resemble Archaeopteryx more than Deinonychus. Among these newly discovered theropods that show remarkable bird-like characteristics are the four-winged theropods Microraptor and Anchiornis, and the unenlagiids Unenlagia, Buitreraptor, and Rahonavis. A bizarre group of minute-sized coelurosaurs, the Scansoriopterygidae, also exhibits some avian similarities that lead some authors to interpret them as more closely related to birds than other dinosaurs. With the aim to explore the phylogenetic relationships of these coelurosaurians and birds, we merged recently published integrative databases, resulting in significant changes in the topological distribution of taxa within Paraves. We present evidence that Dromaeosauridae, Microraptoria, Unenlagiidae, and Anchiornis + Xiaotingia form successive sister taxa of Aves, and that the Scansoriopterygidae are basal coelurosaurians not closely related to birds. The implications in the evolutionary sequence of anatomical characters leading to birds, including the origin of flight, are also considered in light of this new phylogenetic hypothesis.

Book Description
This book synthesises the growing body of evidence which suggests that modern-day birds have evolved from theropod dinosaurs of prehistoric times. The author argues that the ancestor-descendant relationship can also be reversed.
