Book Description
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.

Book Description
Paleontology and Neontology of Cephalopods examines information that throws new light on the evolution of coleoids. This book is part of a multivolume work, The Mollusca, which attempts to provide comprehensive treatment of major areas of molluscan research. The Mollusca is intended to serve several disciplines—zoology, biochemistry, physiology, and paleontology. It will prove useful to researchers and to all others with interests in mollusks. The book begins with a review of the main features of cephalopod evolution. This is followed by separate chapters on the evolution of the gladius in coleoids; the buccal mass of Cephalopoda; beaks of living coleoid Cephalopoda; cephalopod hooks; statoliths of cephalopods; buoyancy and locomotion in recent cephalopods; and evolution of the cephalopod brain and cephalopod statocyst. Subsequent chapters deal with the photophore structure and evolution within the Enoploteuthinae; the interrelationships of genera within the Ommastrephidae; evolutionary pathways traversed by the cephalopod family Cranchiidae; the cephalopod fauna of the European Mediterranean; and the evolution of recent cephalopods.

Book Description
"Ponder and Lindberg provides a breathtaking overview of the evolutionary history of the Mollusca, effectively melding information from anatomy, ecology, genomics, and paleobiology to explore the depths of molluscan phylogeny. Its outstanding success is due to thoughtful planning, focused complementary contributions from 36 expert authors, and careful editing. This volume is a must for malacologists."—Bruce Runnegar, Department of Earth and Space Sciences, University of California, Los Angeles "Our understanding of the phylogeny and evolutionary history of the mollusca has been revolutionized over the past two decades through new molecular data and analysis, and reinvestigation of morphological characters. In this volume Ponder, Lindberg, and their colleagues do a wonderful job of integrating this work to provide new perspectives on the relationships of the major molluscan clades, their evolutionary dynamics, and their history. Particularly timely is the coverage of molluscan evo-devo and genomics."—Douglas H. Erwin, Curator of Paleozoic Invertebrates, National Museum of Natural History

Book Description
Recent biodiversity studies, reported here for the first time, have shown that the molluscan fauna of the Gulf of Mexico is far richer and more complex than previously thought. As a result of these new discoveries, the Gulf malacofauna is shown to contain large numbers of endemic species that reside within four separate biogeographical subdivisions of the larger Carolinian Molluscan Province: the Floridian, Suwannean, Texan, and Yucatanean Subprovinces. These four Gulf biotic components, with each supporting its own endemic fauna, are shown here to be separated by distinct ecological and oceanographic barriers. The resultant physical and genetic isolation has led to the evolution of spectacular sibling species radiations, many unknown and undescribed until now. Some of the most conspicuous and important of these are found in the gastropod families Fasciolariidae, Volutidae, Conidae, Muricidae, and Busyconidae, all of which are dominant predators in their respective benthonic ecosystems. The species within these ecologically important families, along with hundreds of endemic taxa in 50 other gastropod and bivalve families, are illustrated here in Molluscan Faunas of the Gulf of Mexico: Endemism in North America’s Inland Sea on 132 color plates and are discussed in detail in the individual chapters. Special attention is given to the mollusks of poorly studied and virtually unknown ecosystems such as those on the deep reefs off the Florida Keys and Dry Tortugas, the deep water coralline algal beds off western Florida, the Flower Garden Reefs off Texas, the petroleum seeps and brine pools of the Sigsbee Escarpment, the Campeche Bank Archipelago, and the deep water areas at the mouth of the Yucatan Channel. This new book is unlike previous taxonomic surveys of the Gulf of Mexico mollusks in that it highlights only the endemic species and genera and does not cover the large number of widespread Carolinian and Caribbean taxa that occur with them. In this aspect, the book is designed to be an augmentation to previous faunal surveys, adding hundreds more taxa that had been missed in these older surveys or were described after those earlier works had been published. The emphasis on endemic species and species complexes is meant to underscore the special nature of the Gulf of Mexico malacofauna, setting it aside from all others in the Tropical Western Atlantic Region.
