    Description: Die Ordnungen Cerithiimorpha und Littorinimorpha stellen umfangreiche systematische Gruppen innerhalb der basalen Caenogastropoda mit einfachen konisch-orthostrophen Protoconchen dar. Diese Großgruppen lassen sich seit der späten Trias differenzieren und lassen seit der Kreidezeit eine zunehmende Diversität erkennen. Im folgenden werden ausgewählte Vertreter aus fünf Überfamilien und 20 Familien unter besonderer Berücksichtigung ihrer frühontogenetischen Schalen beschrieben und ihre Entwicklungsgeschichte wird seit der Kreide belegt. Die Überfamilie Cerithioidea stellt die Kerngruppe der Cerithiimorpha und war mit der Familie Procerithiidae seit dem Jura weltweit im Flachmarin verbreitet. Form und Skulptur der Larvalschale ermöglichte es, die Gattung Schroederium n.g. von den Gattungen Procerithium und Cryptaulax zu trennen. In der Oberkreide lassen sich die nahe verwandten Familien Cassiopidae, Potamididae, Melanopsidae und Scaliolidae über ihre Protoconchmorphologie sicher von den Procerithiidae differenzieren. Die Familien Batillariidae und Modulidae sind durch ihre charakteristische Embryonalschalenskulptur als Schwestergruppen ausgewiesen. Ihre nahe Verwandtschaft wird auch durch anatomische Daten gestützt. Innerhalb der seit dem Eozän in Protoconcherhaltung dokumentierten Familie Cerithiidae, Unterfamilie Cerithiinae, treten abhängig vom besiedelten Habitat zwei Protoconchtypen auf, die mit zu unterscheidenden Radulatypen korrelieren. Die Unterfamilie Bittiinae konnte über Details der Larvalschalenskulptur seit dem Eozän belegt und von den Cerithiinae differenziert werden. Die Adelphotaxa Planaxidae und Thiaridae mit dem gemeinsamen Merkmal einer Bruttasche im Kopffußbereich sind ebenfalls seit dem Eozän bekannt. Larvalschalen fossiler und rezenter Planaxinae werden vergleichend dargestellt. Larvalschalen der hinsichtlich der Morphologie des Teleoconches abweichenden Unterfamilie Fossarinae belegen die Nähe zur Nominatunterfamilie und ermöglichten eine sichere Abgrenzung von gehäusekonvergenten Vertretern der Littorinimorpha. Über die Formation der frühontogenetischen Schale, die eine charakteristische Embryogenese widerspiegelt, war es möglich, die Brackwasser und limnische Biotope besiedelnden Thiaridae bis in das mittlere Eozän zu belegen, was auch Anlaß zu neuen paläobiogeographischen Interpretationen gab. Pseudamauridae konnten über ihre Protoconche von der Oberkreide bis in das Eozän belegt und von gehäusekonvergenten Naticoidea (Neomesogastropoda) und Amphibolidae innerhalb der Archaeopulmonata (Heterostropha) abgegrenzt werden. Die Phylogenese der Überfamilien Vermetoidea und Turritelloidea wurde von der Unterkreide bis rezent dokumentiert, wobei konvergente Gruppen über ihre Protoconche differenziert wurden. Innerhalb der Littorinimorpha konnten charakteristische Merkmale der Embryonal- und Larvalschalen herausgearbeitet und zur Untergliederung der Littorinoidea und Rissooidea herangezogen werden. Pickworthiidae mit alloisostroph abgewinkelten Protoconchen konnten bis in das Danium belegt werden. Der direkte Vergleich mit Protoconchen der triassischen Protstyliferidae mit detaillierten Übereinstimmungen dokumentiert die unabhängige Evolution dieser Linie. Die konvergenten Vanikoridae ließen sich über ihre Protoconchmorphologie trennen, wobei auch signifikante Unterschiede zu den übrigen Littorinimorpha dargestellt werden. Micromphalina peyrerensis und Megalomphalus (M.) antwerpensis werden neu beschrieben und den Vanikoridae eingegliedert.
    Description: The orders Cerithiimorpha and Littorinimorpha represent large systematic units within the stem of Caenogastropoda with simple conical-orthostrophic protoconchs. These groups are separated since the Upper Triassic showing increasing diversity since the Upper Cretaceous. Representatives of five superfamilies and 20 families are described with special reference to their early ontogenetic shells. The family Procerithiidae within the superfamily Cerithioidea has been distributed worldwide since Jurassic times as a faunal element in shallow marine environments. Regarding the shape and sculpture of its larval shell the procerithiid Schroederium n.g. could be differentiated from the genera Procerithium and Cryptaulax. Since the Upper Cretaceous brackish-water Cassiopidae, Potamididae and Melanopsidae can be differentiated from Procerithiidae by their protoconch-morphology. The families Batillariidae and Modulidae represent Adelphotaxa. This relation is proven by the uniting character of embryonic tuberculated sculpture and data concerning their anatomy. The Cerithiidae, subfamily Cerithiinae, are documented since the Eocene with preserved protoconchs. Two types of larval sculpture are present depending on the settled habitat, correlated with two different types of radulae. The subfamily Bittiinae is also documented and distinguished from the Cerithiinae by their protoconch-morphology since the Eocene. The Adelphotaxa Planaxidae and Thiaridae with the uniting character of a brood pouch within the head-foot are present since the Eocene. Larval shells of fossil and Recent Planaxinae are compared. Protoconchs of representatives of the subfamily Fossarinae with different teleoconch-morphology proved the close relation to the Planaxinae and also made a differentiation from convergent littorinimorphs feasible. The analysis of early ontogenetic shells of brackish water and limnic Thiaridae enabled to trace them back to the Middle Eocene and made new interpretations concerning their palaeobiogeography possible. Pseudamauridae could be documented from the Upper Cretaceous to the Middle Eocene with the aid of preserved protoconchs and could be discriminated from convergent Naticoidea and Archaeopulmonata. The phylogenetic history of Vermetoidea and Turritelloidea could be reconstructed since the Early Cretaceous and convergent groups could be differentiated. Within the Littorinimorpha characters regarding the early shell could be worked out to subdivide Littorinoidea and Rissooidea. Pickworthiidae with alloisostrophic protoconchs are documented since the Danian. Comparison with protoconchs of Triassic Prostyliferidae yielded detailed accordance and documents the independent history of this lineage. The convergent Vanikoridae could be discriminated by their protoconch-morphology and significant differences to the other Littorinimorpha are presented. Micromphalina peyrerensis and Megalomphalus (M.) antwerpensis are described as new species and are included within the Vanikoridae.
