John H. Ostrom's expeditions to the Bighorn Basin of Wyoming and Montana in the 1960s resulted in discoveries and research that would change long-held concepts in paleontology. This fiftieth-anniversary edition of his now well-known description of the type specimen of Deinonychus antirrhopus revisits the work that redefined theropod dinosaurs as the intelligent, agile, and gregarious ancestors of modern birds and led in the late twentieth century to a renaissance in the study of dinosaurs and the evolution of flight.

The fiftieth anniversary edition of a landmark publication showcasing prehistoric North American landscapes and ecosystems, from a celebrated paleontologist at Yale University's Peabody Museum The fiftieth anniversary edition of John H. Ostrom's Stratigraphy and Paleontology of the Cloverly Formation revisits his groundbreaking work pinpointing the age of the continental sequence of the Bighorn Basin area in Wyoming and Montana. The Cloverly Formation is important for understanding the development of North American terrestrial landscapes and prehistoric ecosystems, and current investigations are reinterpreting the age of the Formation with new evidence and data. The reissue of Ostrom's original benchmark research offers contemporary relevance for researchers and students today.

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.

This fascinating book tells the story of how one museum changed ideas about dinosaurs, dynasties, and even the story of life on earth. The Yale Peabody Museum of Natural History, now celebrating its 150th anniversary, has remade the way we see the world. Delving into the museum’s storied and colorful past, award-winning author Richard Conniff introduces a cast of bold explorers, roughneck bone hunters, and visionary scientists. Some became famous for wresting Brontosaurus, Triceratops, and other dinosaurs from the earth, others pioneered the introduction of science education in North America, and still others rediscovered the long-buried glory of Machu Picchu. In this lively tale of events, achievements, and scandals from throughout the museum’s history. Readers will encounter renowned paleontologist O. C. Marsh who engaged in ferocious combat with his “Bone Wars” rival Edward Drinker Cope, as well as dozens of other intriguing characters. Nearly 100 color images portray important figures in the Peabody’s history and special objects from the museum’s 13-million-item collections. For anyone with an interest in exploring, understanding, and protecting the natural world, this book will deliver abundant delights.

Geared toward a broad variety of students, Dinosaurs: The Textbook offers a concise and lucid presentation of the core biological and geological concepts of dinosaur science. Revised throughout to reflect recent fossil discoveries and the current scientific consensus, this seventh edition details the evolution, phylogeny, and classification of various dinosaur species while modeling the best approach for navigating new and existing research. Spencer G. Lucas takes readers through the major taxonomic groups, including theropods, sauropodomorphs, ornithopods, ceratopsians, pachycephalosaurs, stegosaurs, and ankylosaurs. He also examines the behavior and extinction of the dinosaurs, their biological relationship to birds, and their representation (or misrepresentation) in art, literature, film, and other forms of popular culture. This seventh edition of the leading text for introductory courses on dinosaurs incorporates comprehensive updates based on the latest research. Lucas highlights how dinosaur science is rapidly evolving, exploring how new discoveries, methods, and ideas are expanding the frontiers of knowledge. The book features cutting-edge and scientifically rigorous illustrations by leading paleoartists. It also includes extensive and reader-friendly end-of-chapter summary tools, review questions, a detailed glossary, a dinosaur dictionary, and a comprehensive index.
