"Two original scientific descriptions by John H. Ostrom of the fossil type specimen of the Early Cretaceous biped theropod dinosaur Deinonychus antirrhopus presenting its avian-like skeletal anatomy, adaptations, habits, and affinities, research on functional morphology and the evolution of birds that led to the 'dinosaur renaissance' at the end of the 20th century"--
John H. Ostroms 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.
