“…The suggestion by SalviniPlawen & Haszprunar (1987) to insert between Vetigastropoda and Caenogastropoda an independent order Seguenziina, which was adopted as suborder of the order Vetigastropoda by Marshall (1988Marshall ( , 1991, also cannot be supported. The results of Williams et al (2008Williams et al ( , 2010 according to which a separate branch of the Vetigastropoda including the Seguenzioidea can be distinguished from another one including the Trochoidea is supported by the paleontological evidence. These branches were distinct from each other as early as the time of deposition of Triassic St. Cassian Formation 220 Ma ago.…”

“…The first known appearances of Seguenziidae were much later, in the Late Cretaceous (assumed by Hickman 1998) and Cenozoic (documented by Marshall 1983), but their apparent absence in older sediments was attributed by Kano et al (2009) to difficulties in determining phylogenetic positions of fossils solely by shell characters. Williams et al (2008) estimated the divergence of Seguenzioidea from Scissurellidae, Lepetodrilidae, Fissurellidae to have taken place 124-221 Ma ago, based on molecular data derived from various Vetigastropoda and confirmed by Williams et al (2010).…”

“…Kano et al (2009) summarized that Vetigastropoda are an archaic and diverse group of Gastropoda, comprising several thousand living species. Their systematic interpretation has changed former classification schemes and reconstruction of phylogeny considerably due to the molecular analysis and by including data presented by Warén et al (2003), Geiger & Thacker (2005), Williams & Ozawa (2006), Kano (2008) and Williams et al (2008Williams et al ( , 2010. Hickman & McLean (1990) placing their main emphasis on the characters of living species suggested that the Eucyclinae represent a subfamily of the Trochidae, in turn a family of the Trochoidea.…”

The aim of this study is to document the relationship that may exist between Triassic species of Eucycloscala, Ampezzotrochus, Sabrinella, Microcheilus, Eunemopsis and Pseudoclanculus and living species of genera such as Pagodatrochus, Turcica, Calliotropis, Danilia, and Euchelus. Their shell has a nacreous inner layer and ornament of axial ribs on the early teleoconch. This ornament distinguishes from living and fossil Vetigastropoda with Trochus, and Turbo-like shells. Eucycloscalidae, containing the Triassic genera Eucycloscala and Ampezzotrochus, can be distinguished from Eunemopsis and Pseudoclanculus and the Eunemopsidae fam. nov. by folds on the inner lip and Sabrinellidae fam. nov. with Sabrinella and Microcheilus by the varix of the aperture of the last whorl. Lanascala with Lanascalidae belongs here. Neoeunema gen. nov. represents a Triassic member of Eucyclidae, which contains numerous Jurassic genera and species. Pseudoturcicidae fam. nov. differs by the ornament of the early teleoconch. The Chilodontidae form a characteristic Cretaceous group with teeth on the inner side of their outer lip. Three families of modern genera can be distinguished by the arrangement of teeth in the radula: four pairs in Pagodatrochidae fam. nov. and Turcicidae fam. nov., and three pairs in Calliotropidae, documented with Euchelus. The Seguenzioidea represents a related group having a distinctive radula with two lateral pairs of teeth and a variety of shell shapes and ornament. The early teleoconch of Seguenziidae (with slit in the aperture) and Ancistrobasidae fam. nov. (without such a slit) resembles that of the Eucycloscalidae, but has a strong spiral rib in addition to the axial ribs. The new species Microcheilus maxwelli sp. nov., Eucycloidea madagascariensis sp. nov., new genera Pseudoturcica and Heterodiscohelix, and new families Sabrinellidae fam. nov., Euemopsidae fam. nov., Pseudoturcidae fam. nov., Pagodatrochidae fam. nov. Turcicidae fam. nov., and Ancistrobasidae fam. nov. are introduced. The fossil record confirms existence of two independent branches of Vetigastropoda since more than 220 Ma, and within one of these branches parallel to the Eucycloidea the Seguenzioidea since Mesozoic times

“…Cantharidella has usually been placed in a subfamily Gibbulinae, but Williams et al (2008:15) pointed out that the blue-green nacre that characterizes Trochidae Cantharidinae, as compared with the more usual colourless to pearly nacre of other trochoideans, is also present in Gibbula and Cantharidella. In a wider molecular study, Williams et al (2010) showed that Gibbula and Cantharidella belong in the Cantharidinae.…”

Recent expeditions have revealed high levels of biodiversity in the tropical deep-sea, yet little is known about the age or origin of this biodiversity, and large-scale molecular studies are still few in number. In this study, we had access to the largest number of solariellid gastropods ever collected for molecular studies, including many rare and unusual taxa. We used a Bayesian chronogram of these deep-sea gastropods (1) to test the hypothesis that deep-water communities arose onshore, (2) to determine whether Antarctica acted as a source of diversity for deep-water communities elsewhere and (3) to determine how factors like global climate change have affected evolution on the continental slope. We show that although fossil data suggest that solariellid gastropods likely arose in a shallow, tropical environment, interpretation of the molecular data is equivocal with respect to the origin of the group. On the other hand, the molecular data clearly show that Antarctic species sampled represent a recent invasion, rather than a relictual ancestral lineage. We also show that an abrupt period of global warming during the Palaeocene Eocene Thermal Maximum (PETM) leaves no molecular record of change in diversification rate in solariellids and that the group radiated before the PETM. Conversely, there is a substantial, although not significant increase in the rate of diversification of a major clade approximately 33.7 Mya, coinciding with a period of global cooling at the Eocene–Oligocene transition. Increased nutrients made available by contemporaneous changes to erosion, ocean circulation, tectonic events and upwelling may explain increased diversification, suggesting that food availability may have been a factor limiting exploitation of deep-sea habitats. Tectonic events that shaped diversification in reef-associated taxa and deep-water squat lobsters in central Indo-West Pacific were also probably important in the evolution of solariellids during the Oligo-Miocene.
