"This volume includes detailed accounts of the morphology and distribution of the fossil snakes of North America and also remarks on their evolutionary, zoogeographic, and paleoecological patterns. The heart of the book consists of detailed systematic accounts of the known fossil snakes of North America and their localities. Extinct fossil taxa are discussed and illustrated, and many are re-described on the basis of new information. The book provides illustrations of diagnostic vertebrae and criteria for the identification of presently living fossil snake taxa as well as descriptions of the modern characteristics and ranges of these species." "Color photographs in the 16-page insert present a catalog of representative living snake species." --Book Jacket.

The heart of this book consists of detailed systematic accounts of the known fossil frogs and toads (anurans) of North America and their localities. Extinct fossil frogs and toads are fully discussed and illustrated, and in some cases are re-diagnosed and re-described. For fossil taxa still living, the book gives the modern characteristics, ecological attributes, and modern ranges, and includes illustrations of diagnostic skeletal elements. The volume begins with an overview of the anurans and anuran studies, a general account of the skeleton and bones, and a discussion of the early evolution of the Anura, along with the formal classification of anuran taxonomic groups found in the North American fossil record. The third part of the book presents an epoch-by-epoch discussion of Mesozoic, Tertiary, and Pleistocene anurans, the classification and phylogeny of the anurans, and a comprehensive list of references.

The first treatise to be published in thirty years on the 58 snakes found in eastern North America, Snakes of Eastern North America provides a current summary of the taxonomy, ecology, and behavior of each species. Selected by CHOICE as Outstanding Academic book of 1989. Table of Contents: Preface; Introduction; Identification of Snakes; Typhlopidae: Blind Snakes; Colubridae: Colubrid Snakes; Glossary of Scientific Names; Bibliography; Index

The book concludes with a discussion of the study of fossil salamanders as it relates to the development of a realistic phylogeny and classification of the group.

Providing thorough descriptions of almost 200 species, this guide presents thousands of facts and figures that will help you identify, understand, and appreciate these important and remarkable animals. Each species and subspecies account includes the latest findings on abundance, size, reproductive habits, prey, habitat, behavior and venomous/nonvenomous status.

Many people fear snakes, and watersnakes in particular have one of the worst reputations of any snake found in North America. Some species are commonly mistaken for venomous cottonmouths, and a few may eat popular game fishes. Unfortunately, few people realize the important roles many watersnakes play in natural ecosystems and, consequently, they are still persecuted in many regions today. Seeking to overcome common misperceptions, J. Whitfield Gibbons and Michael E. Dorcas have compiled North American Watersnakes, the first comprehensive study of all fourteen species of watersnakes found in the United States, Canada, Mexico, and Cuba. Individual species accounts explore all aspects of the natural history of watersnakes in North America, including their behavior, physiology, life history, ecology, and conservation. Almost 100 color photographs accompany the text, illustrating all 14 species and nearly all subspecies. Supplementing the species accounts are detailed color maps depicting each species distribution and stunning black-and-white drawings by Peri Mason. Easy-to-use keys help readers to identify specimens at hand.
