TAXONOMIC DIVERSIFICATION OF NORMAL-MARINE BIVALVE MOLLUSKS IN THE PHANEROZOIC

Abstract

The dynamics of the taxonomic diversification of normal-marine bivalve mollusks and that of the entire fossil marine skeletal fauna are compared. A major Early Permian turnover has been revealed. The changes in the proportions of the bivalve mollusks to the entire marine fauna during the Phanerozoic are studied. © Pleiades Publishing, Inc. 2006.
