AbstractThe following groups of Mesozoic Caenogastropoda are discussed here: Cerithioidea and Littorinoidea-Rissooidea seemingly merging with each other during Triassic times; the fresh water and land snails of the Viviparoidea and Cyclophoroidea with unknown marine relatives but a Mesozoic history; the Vermetoidea, Turritelloidea and Campaniloidea with a late appearance in the Mesozoic; the Ctenoglossa with a continuous history from the Middle Palaeozoic to modern times; the Subulitoidea, Murchisonioidea and Loxonematoidea with Palaeozoic ancestors but unclear Middle Mesozoic relations; the Purpurinoidea as potential ancestors and relatives of the Stromboidea, the latter suddenly appearing in the Jurassic; the Heteropoda and Vanikoroidea with possible relation to each other but very uncertain relations to the others; and the Neomesogastropoda and Neogastropoda which begin their history in the Mid Cretaceous with still rather uncertain precursors.
