>The rich fossil record of the Atlantic and Gulf coastal plains of the United States is a gold mine for interested scientists. The last thirty million years of Earth history are superbly chronicled by a succession of fossil assemblages extending from the St. Lawrence River to Florida. Marine scientists, paleontologists, and systematic biologists al

Shallow water marine molluscan faunas are distributed in a pattern of distinct, geographically definable areas. This makes mollusks ideal for studying the distribution of organisms in the marine environment and the processes and patterns that control their evolution. Biogeography and Biodiversity of Western Atlantic Mollusks is the first book to us

Marine biogeography, the study of the spatial distribution of organisms in the world’s oceans, is one of the most fascinating branches of oceanography. This book continues the pioneering research into the distributions of molluscan faunas, first studied by biologists over 160 years ago. It illustrates 1778 species of gastropods in full color, many of which are extremely rare and poorly known endemic species that are illustrated for the first time outside of their original descriptions. The spatial arrangements of malacofaunas shown in this book can be considered proxies for worldwide oceanic conditions and used as tools for determining patterns of global climate change. The book's documentation of evolutionary "hot spots" and geographically restricted endemic faunas can also be used as a base line for future studies on patterns of environmental deterioration and extinction in the marine biosphere. Documenting the evolution of the amazingly rich worldwide gastropod fauna, this book will appeal to physical and chemical oceanographers, systematic and evolutionary biologists, historical geologists, paleontologists, climatologists, geomorphologists, and physical geographers. The authors incorporate aspects of all of these disciplines into a new classification system for the nomenclature of biogeographical spatial units found in tropical, subtropical, and warm temperate seas.

Conus is the largest genus of animals in the sea, occurring throughout the world's tropical and subtropical oceans and contributing significantly to marine biodiversity. The shells of these marine mollusks are prized for their amazing variety and extraordinary beauty. The neurotoxic venoms they produce—injected by a hollow, harpoon-like tooth into prey animals that are then paralyzed and swallowed whole—have a range of pharmaceutical applications, from painkillers to antidepressants. This beautifully illustrated book identifies 53 valid species of the southeastern United States and the Caribbean, a region that supports a diverse but taxonomically challenging group of Conus. Introductory chapters cover the evolution and phylogeny of the genus, and notes on methodology are provided. Detailed species accounts describe key identification features, taxonomy, distribution, ecology, toxicology, life history, and evolutionary relationships. The book includes more than 2,100 photos of shells on 109 splendid color plates; more than 100 additional photos, many depicting live animals in color; and 35 color distribution maps. Identifies 53 valid species—the first reassessment of western Atlantic Conus in more than seventy years Features more than 2,100 photos of shells on 109 color plates Blends the traditional shell-character approach to identification with cutting-edge shell and radular tooth morphometrics and molecular genetic analyses Includes color images of live animals as well as color distribution maps

The Chesapeake Miocene will always be considered a paleontological treasure. Given the richness and accessibility of the Maryland and Virginia Miocene shell beds, it seems remarkable that very few people have ever described new species from these strata over the past 185 years. Until now. Integrating elements from paleontology, geology, environmental science, and ecology, Molluscan Paleontology of the Chesapeake Miocene assembles previous research and the authors’ experience into a synoptic field guide. The most complete compendium of Miocene species created since 1904, this long-awaited resource lists nearly 500 species. It contains illustrations of 260 species, including more than 60 not found in any previous book and 26 newly discovered. It describes Chesapeake molluscan faunas in terms of local geology, paleoceanography, and marine paleobiology. Organized by stratigraphic geology, the book covers fossils of the Eastover, St Mary’s, Choptank, and Calvert Formations. It illustrates 24 collecting sites and fossil exposures, showing details of in situ specimens, along with maps of 4 Miocene paleoseas and detailed stratigraphic columns for Maryland and northern Virginia. The text is accompanied by downloadable resources with color illustrations of the forty known species of ecphora shells. Armed with these, you should be able to identify the species found in the amazingly rich shell beds of the Chesapeake Bay area.
