In this book, a total of 103 fossil cone species are redescribed and presented on 30 figure plates, their time ranges are compared in a diagram, and two new genera are introduced (Herndliconus, p. 60, and Tequestaconus, p. 62). To each genus a picture of the type species is shown, and, wherever necessary, pictures of important conchological features are added after every description. As opposed to the "Compendium of Fossil Shells of Florida", Petuch & Drolshage, 2011, the shells on the figure plates are shown in true proportion, to give a visual overview of the dimensions of the single species in comparison to their congeners - an important distinguishing feature in identifying them. As a contribution to, and a summary of our present knowledge of fossil cones of southern Florida, this book represents the culmination of over 40 years of field research by the senior author. 179 pp., 30 color pls, num. text figs, hc 4.…

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 a CD-ROM 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. 168 pp, 60 b/w figs, hardcover gr. 8. …
