Download or read book Fossil Snakes of North America written by J. Alan Holman and published by Indiana University Press. This book was released on 2000 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: "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.

Download or read book Handbook of Lizards written by Hobart Smith and published by Cornell University Press. This book was released on 2018-04-11 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most thorough treatment of lizards of the United States and Canada when first published in 1946, Handbook of Lizards has become a landmark among herpetologists and lizard specialists. Hobart M. Smith spent years compiling and organizing information on 136 species of lizards for this classic study. With more than 300 illustrations, including black-and-white photographs, labeled drawings, range maps, and illustrated keys, this volume serves as a still-relevant and convenient reference guide to the study of North American lizards. Darrel Frost, a prominent lizard specialist, provides a foreword for the 1995 paperback edition that underscores the work's relevance for herpetology today. In the first section, Smith covers in concise fashion the habits, life history, habitats, methods of collection and preservation, and structural features of lizards. The second section of the book considers each species under topics that are conveniently arranged for studying both living lizards and laboratory specimens: range, type, locality, size, color, scalation, recognition characters, habitat and habits, and references. Smith also discusses problems for further study and gives recommendations for special investigations of each species. The book concludes with an extensive bibliography.

Download or read book Pleistocene Amphibians and Reptiles in North America written by J. Alan Holman and published by Oxford University Press on Demand. This book was released on 1995 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a major summary of what is currently known about North American amphibians and fossils in the Pleistocene. The only book available on the subject, it includes a general treatment of the Pleistocene and its effects on the physical and biological world, and features an illustrated bestiary of the herpetological families and genera as well as a discussion of the identification of fossils. The changes in the North American herpetofauna from the Cretaceous to the Pleistocene are cogently summarized, and complete herpetofaunal lists from the seven designated Pleistocene regions of North America are included. The concluding chapter details range adjustments and extinction patterns, and contrasts the evolutionary "stasis" of the herpetofauna with the avian and mammalian fauna. The work will be considered an essential reference for paleontologists.

Available in PDF, EPUB and Kindle. Book excerpt: Terrestrial ecosystems changed substantially during the Cenozoic era. The early Cenozoic was characterized by a warm and wet climate and ecosystems reminiscent of the modern tropics. Plant and animal communities similar to the modern biota were hypothesized to have appeared during the Miocene epoch. The phylogenetic, ecologic, and biogeographic assembly of the modern biota in North America and during the Miocene is well studied among fossil mammals and plants, but is not well documented in ectothermic vertebrates, such as lizards. I employed paleontological, biological, and geological data to address the formation of the modern lizard biota in North America, focusing on pleurodontan lizards (horned lizards, anoles, and relatives) and alligator lizards, which are prominent groups in modern ecosystems. My dissertation comprises three research foci: 1) Descriptions of fossil lizards, primarily from the Miocene but also from the Oligocene and Eocene, to evaluate paleodiversity, paleoecology, and paleobiogeography of focal lizard groups, 2) divergence time estimation using published genetic data and fossil calibrations to temporally constrain the evolution of focal lizard groups, and 3) exploration of fossil identification methodologies, especially fossil diagnoses made in the context of alternative phylogenetic hypotheses. I found one relatively modern lizard fauna from the middle Miocene of Wyoming that corroborates the records of terrestrial plants and mammals. However, I also described fossil occurrences that defy biogeographical (e.g., Abronia from the middle Miocene of California) and ecological (e.g., Uma from the late Miocene of California) expectations based on the biology of living lizards. The fields of historical biogeography and paleoecology draw heavily from the modern biota to make inferences into the past, but I suggest caution in that practice, because the distributions and ecological tolerances of organisms change through time. In the process of diagnosing and identifying a new fossil lizard (Kopidosaurus), I found that attention to phylogenetic hypotheses derived from molecular datasets altered the inferred phylogenetic position of the new taxon. Phylogenetic analyses are a popular avenue among paleontologists for fossil diagnosis, and neglecting alternative phylogenetic hypotheses can hinder fossil diagnosis and all downstream hypotheses that are contingent on accurate fossil diagnosis

Book excerpt: Concise detailed review — amply illustrated — of the astonishing creatures that ruled the earth for some 180 million years, with particular emphasis on the tetrapods (four-legged vertebrates that lived during the years of reptilian dominance). Also examines interrelationships between amphibians and reptiles, birds and mammals, and between these creatures and their environments.
