  title={Molecular phylogeny of Vetigastropoda reveals non-monophyletic Scissurellidae , Trochoidea , and Fissurelloidea},
  author={Daniel L. Geiger and Christine E. Thacker}
}
A molecular phylogeny using cytochrome c oxidase subunit 1, Histone H3, and 18S rRNA, comprising 3038 aligned characters, was developed for 38 ingroup vetigastropods and two neritimorph outgroups. Vetigastropoda is diagnosed by the presence of bursicles and their presence and absence in putative vetigastropod groups is discussed. The molecular data support the monophyly of Fissurellidae, Haliotidae, Lepetodrilidae, Pleurotomariidae, and Peltospiridae; single exemplar taxa were available for… 

Figures and Tables from this paper

Vetigastropod phylogeny and a new concept of Seguenzioidea: independent evolution of copulatory organs in the deep‐sea habitats
TLDR
Bayesian and maximum‐likelihood phylogenies of Vetigastropoda were reconstructed by separate and combined analyses of one mitochondrial, one nuclear and two nuclear gene sequences, with an emphasis on dense taxonomic sampling.
Mitogenomics of Vetigastropoda: insights into the evolution of pallial symmetry
TLDR
The new phylogeny supports that the loss of the right pallial gill occurred multiple times in vetigastropod evolution as previously suggested and that Phasianelloidea, Angarioidea and Trochoidea radiated from a common asymmetric (single‐gilled) ancestor that lived in the middle Palaeozoic.
Denser mitogenomic sampling improves resolution of the phylogeny of the superfamily Trochoidea (Gastropoda: Vetigastropoda)
TLDR
The phylogenetic trees were reconstructed using probabilistic methods with Neomphalina as outgroup and recovered with maximal support a clade of Trochoidea sensu Hickman & McLean (1990, Nat. Hist. Mus. Series, 35: 1–169).
Molecular systematics of Vetigastropoda: Trochidae, Turbinidae and Trochoidea redefined
TLDR
Bayesian analyses of sequences from three genes including data from 162 vetigastropod species show that the gastropod family Trochidae is not monophyletic, and the family makes up the superfamily Trochoidea.
Morphological phylogeny of the Tegulinae (Mollusca: Vetigastropoda) reinforces a Turbinidae position
TLDR
The authors' morphological data provide a solid foundation for ensuing systematic research on Tegulinae, as well as Trochoidea, and evidence facilitating the diagnosis of generic and suprageneric groups.
Eight new species of Scissurellidae and Anatomidae (Mollusca: Gastropoda: Vetigastropoda) from around the world, with discussion of two new senior synonyms
TLDR
Eight new species of Scissurellidae and Anatomidae are described and three new synonymies are identified based on examination of type material in the Museum Nationale dHistoire Naturelle, Paris.
Four new species of Anatomidae (Mollusca: Vetigastropoda) from the Indian Ocean (Reunion, Mayotte) and Australia, with notes on a novel radular type for the family
Four new species of Anatomidae are described: Anatoma herberti n. sp. with strong axial sculpture on the shoulder and base; A. austrolissa n. sp. with almost smooth sculpture except for axial cords
A phylogeny of Vetigastropoda and other “archaeogastropods”: re‐organizing old gastropod clades
TLDR
In the likelihood and POY optimal phylogenetic analyses, Gastropoda, Caenogastrooda, Neritimorpha, Neomphalina, and Patellogastropoda were monophyletic.
A phylogenomic framework for Vetigastropoda (Mollusca)
TLDR
The first genomic-scale dataset focused on vetigastropods is presented, including a comprehensive sampling of taxa with all superfamilies and about half of the extant families (41 new transcriptomes, 49 total ingroup terminals), and recovered topology is congruent among inference methods for the majority of nodes.
Spermatogenesis in Serpulorbis (Mollusca: Vermetoidea) and its implications for phylogeny of gastropods
TLDR
Evidence supports the conclusion of Healy (1988b) that Vermetoidea are not closely related to “lower” caenogastropods, such as Cerithioidea and related groups and for the first time, nuclear degradation in parasperm of VermetOidea is shown to progress by an apoptotic mechanism.

Phylogeny and relationships of pleurotomariid gastropods (Mollusca: Gastropoda): an assessment based on partial 18S rDNA and cytochrome c oxidase I sequences.
TLDR
The phylogenetic position of the ancient family Pleurotomariidae within the Molluscan class Gastropoda, as well as the relationships of its Recent genera and species, were assessed using an iterative, two-gene approach to phylogeny reconstruction.
Phylogenetic assessment of characters proposed for the generic classification of Recent Scissurellidae (Gastropoda : Vetigastropoda) with a description of one new genus and six new species from Easter Island and Australia
TLDR
Cladistic analysis based on shell and radular characteristics, using autapomorphies to code inapplicables, revealed several patterns and revealed that scissurelline protoconch sculpture is highly homoplastic.
Gastropod evolutionary rates and phylogenetic relationships assessed using partial 28S rDNA and histone H3 sequences
TLDR
The data support the monophyly of the Patellogastropoda (true limpets), Euthyneura and the ‘higher’ vetigastropods and the polyphyly ofThe ‘Cocculiniformia’, and show marked variability in the rate of evolution in both segments of the 28S rDNA, whether or not the expansion regions are included.
A molecular phylogeny of the Patellogastropoda (Mollusca: Gastropoda)
TLDR
Partial 18S sequences support the inclusion of the family Neolepetopsidae within the superfamily Acmaeoidea, and refute its previously hypothesized position as sister group to the remaining living Patellogastropoda.
First molecular evidence for the existence of a Tardigrada + Arthropoda clade.
TLDR
The results obtained represent the first molecular evidence for a Tardigrada + Arthropoda clade and indicate the need to review those obtained solely on morphological characters.
Anatomy and systematics of bathyphytophilid limpets (Mollusca, Archaeogastropoda) from the northeastern Pacific
TLDR
Autapomorphic characters of shell, radula and anatomy confirm the placement of Bathyphytophilus (with Aenigmabonus) in a distinct family close to the Lepetellidae, Pyropeltidae, and Pseudococculinidae.
Towards a phylogeny of gastropod molluscs: an analysis using morphological characters
TLDR
This is one of the first attempts to use Morphological and developmental characters to assess the relationships of all major clades using parsimony methods and discusses the major monophyletic groups within gastropods.
Phylogeny of the Cocculinoidea (Mollusca, Gastropoda)
TLDR
Character optimization demonstrates that many characters often cited as diagnostic of various taxa, are often homoplastic and/or synapomorphies at different hierarchical levels.
On bivalve phylogeny: a high‐level analysis of the Bivalvia (Mollusca) based on combined morphology and DNA sequence data
Abstract. Bivalve classification has suffered in the past from the crossed-purpose discussions among paleontologists and neontologists, and many have based their proposals on single character
Gastropod phylogeny based on six segments from four genes representing coding or non-coding and mitochondrial or nuclear DNA
TLDR
Additional data was collected from three gene segments and analyses of these data using cladistic, maximum likelihood or Bayesian methodologies were conducted in an attempt to resolve some of the differences between current hypotheses of gastropod relationships based on morphological and molecular data.
