The Osteology of Reptiles and Amphibians: A Modern Comparative Atlas of North American Species is a comprehensive guide on all skeletal systems and bone compositions of herpetofauna, including turtles, crocodiles, lizards, and snakes. This book looks at the largest concentration of reptilian and amphibian species found across the United States, Canada, Mexico, and beyond. Fundamental overviews and descriptions for osteological identification, herpetological evolution, and the study of functional and comparative morphology are covered. Line drawings separated by bone type from all major herpetofauna groups round out the content. Users will find detailed, scaled content that allows researchers to collect data within major groups. This book represents the first of its kind, offering herpetologists, vertebrate biologists, paleontologists, and zooarchaelogists a core visual resource for studying and understanding herpetofauna osteology. It will also be useful for students in animal biology, herpetology, and osteology courses.
