Book Description The growth history of a brachiopod is entombed in its shell, but research on fossil and living brachiopods has generated unanswered questions about these marine invertebrates. Several contributors to Brachiopods Past and Present comment on . This collection of conference papers presents information on the molecular genetics, biomineralization, growth and ecology of extant brachiopod stocks (extrapolated back to the Cambrian), and the shell microstructure, taphonomy, paleogeography, evolution, and taxonomy of fossil brachiopods. The book emphasizes skeletal formation and fossilization in a geologic framework in order to understand evolution, relationships between fossil groups, and the use of biomineral materials as geochemical proxies for understanding ancient oceans and climates.

The Devonian* saw the peak of marine faunal diversity during the Paleozoic Era. New predators such as sharks, bony fishes and ammonoids ruled the oceans. Trilobites continued their decline, while brachiopods became the most abundant marine organism. A wonderful assemblage in the collection has fragments of trilobite (Phacops rana milleri), brachiopod (Sulcoretepora deissi) and.
