dc.description.abstract"A Lower Mississippian (Kinderhookian) gastropod fauna is described from the Wassonville Formation in southeastern Iowa. This represents one of the few well-preserved Lower Mississippian gastropod faunas known from North America and, as such, contributes to our understanding of a rather critical time in the evolution of Paleozoic gastropods. Twenty-eight species are described, eight of which are new. The new taxa are: Sinuitina nudidorsa, Platyschisma laudoni, Trepospira (Angyomphalus) penelenticulata, Baylea angulosa, Glabrocingulum (Glabrocingulum) minutum, Glyptotomaria (Dictyotomaria) quasicapillaria, Cerithioides judiae, and Baylea trifibra. An unexpected aspect of the Wassonville gastropod fauna is that it shows greater taxonomic affinity with the European Carboniferous than with other North American Carboniferous faunas. This probably reflects the paucity of described North American Mississippian gastropod faunas and the increased understanding, through recent study (notably Batten, 1966), of British and Belgium Tournaisian and Visean gastropods. The genus Cerithiodes, long known from the Upper Paleozoic of Europe, is recognized for the first time in the Carboniferous of North America"--P. [1].en_US
