Summary

The most complete compendium of Miocene species since 1904, this long-awaited field guide lists nearly 500 species. 260 species are fully illustrated, including more than 60 not found in any previous book and 26 newly discovered. It describes Chesapeake molluscan faunas in terms of local geography, paleoceanography, and marine paleobiology. Organized by stratigraphic geography, the book covers fossils of the Eastover, St Mary's, Choptank, and Calvert Formations. It illustrates 10 classic Miocene exposures along with close-up photos of various Miocene shell beds, molluscan assemblages, and individual "in situ" specimens. The text is accompanied by a CD-ROM with full color illustrations.
