How does the continental fossil record contribute to our understanding of the history of Phanerozoic diversification? Is it distinct from the well-studied record of marine invertebrates? In an analysis of bivalve and gastropod molluscs, marine and continental fauna have greatly dissimilar patterns of diversification. I assessed the taxonomic survivorship, environmental distribution and physiological adaptations of these molluscan clades to assess the degree of influence that the “estuary effect” may have had on their diversification. Utilizing data from the Paleobiology Database and the Lake Faunas Through Time database, this study shows that, for bivalves and gastropods, continental invasion is associated with a greater diversification within the clade than exclusively marine faunas. High taxonomic richness is strongly associated with continentality and highly derived gill morphologies in both bivalves and gastropods that allow for osmoregulation, sediment filtration and advanced feeding mechanisms.
