Book Description
Invertebrate Palaeontology and Evolution is well establishedas the foremost palaeontology text at the undergraduate level. Thisfully revised fourth edition includes a complete update of thesections on evolution and the fossil record, and the evolution ofthe early metazoans. New work on the classification of the major phyla (inparticular brachiopods and molluscs) has been incorporated. The section on trace fossils is extensively rewritten. The author has taken care to involve specialists in the majorgroups, to ensure the taxonomy is as up-to-date and accurate aspossible.

Book Description
All organisms and species are transitory, yet life endures. The origin, extinction, and evolution of species—interconnected in the web of life as "eternal ephemera"—are the concern of evolutionary biology. In this riveting work, renowned paleontologist Niles Eldredge follows leading thinkers as they have wrestled for more than two hundred years with the eternal skein of life composed of ephemeral beings, revitalizing evolutionary science with their own, more resilient findings. Eldredge begins in France with the naturalist Jean-Baptiste Lamarck, who in 1801 first framed the overarching question about the emergence of new species. The Italian geologist Giambattista Brocchi followed, bringing in geology and paleontology to expand the question. In 1825, at the University of Edinburgh, Robert Grant and Robert Jameson introduced the astounding ideas formulated by Lamarck and Brocchi to a young medical student named Charles Darwin. Who can doubt that Darwin left for his voyage on the Beagle in 1831 filled with thoughts about these daring new explanations for the "transmutation" of species. Eldredge revisits Darwin's early insights into evolution in South America and his later synthesis of knowledge into a theory of the origin of species. He then considers the ideas of more recent evolutionary thinkers, such as George Gaylord Simpson, Ernst Mayr, and Theodosius Dobzhansky, as well as the young and brash Niles Eldredge and Steven Jay Gould, who set science afire with their concept of punctuated equilibria. Filled with insights into evolutionary biology and told with a rich affection for the scientific arena, this book celebrates the organic, vital relationship between scientific thinking and its subjects.

Book Description
"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.
