註釋

Distribution and habitat preferences of molluscan species in the southwest U.S. are used to make inferences about paleohabitats and past biogeographical patterns. All of the fossil faunas studied are richer in species (approximately 52 were recovered) than extant faunas occupying the same areas today.
