Lophospiridae is an extinct taxonomic family of sea snails, marine gastropod molluscs. [2]
This family has no subfamilies.
Lophospiridae contains the following genera: [3] [4]
Muricidae is a large and varied taxonomic family of small to large predatory sea snails, marine gastropod mollusks, commonly known as murex snails or rock snails. With over 1,700 living species, the Muricidae represent almost 10% of the Neogastropoda. Additionally, 1,200 fossil species have been recognized. Numerous subfamilies are recognized, although experts disagree about the subfamily divisions and the definitions of the genera. Many muricids have unusual shells which are considered attractive by shell collectors and by interior designers.
The Bellerophontidae are an extinct family of specialized globose bellerophontids, Paleozoic and early Triassic mollusks of the class Gastropoda.
Clausiliidae, also known by the common name door snails, is a taxonomic family of small, very elongate, mostly left-handed, air-breathing land snails, sinistral terrestrial pulmonate gastropod mollusks.
Trochoidea is a superfamily of small to very large vetigastropod sea snails with gills and an operculum. Species within this superfamily have nacre as the inner shell layer. The families within this superfamily include the Trochidae, the top snails. This superfamily is the largest vetigastropodan superfamily, containing more than 2,000 species.
Helcionelloida is an extinct group of ancient molluscs. These are the oldest known conchiferan molluscs, that is, they had a mineralised shell. Some members of this class were mistaken for Monoplacophorans. The class was erected by Peel in 1991.
Murchisoniidae is an extinct family of fossil gastropods in the superfamily Murchisonioidea.
Eucyclidae is a family of gastropods in the superfamily Seguenzioidea.
The family Pomatiidae is a taxonomic family of small operculate land snails, terrestrial gastropod mollusks that can be found over the warmer parts of the Old World. In the older literature, this family is designated as Pomatiasidae.
Acteonellidae is an extinct family of gastropods in the informal group Lower Heterobranchia.
Murchisonioidea is an extinct superfamily of small to large sea snails, marine gastropod mollusks in the clade Vetigastropoda.
Porcellioidea is an extinct superfamily of small to large sea snails, marine gastropod mollusks in the clade Vetigastropoda.
Pupilloidea is a superfamily of small and very small air-breathing land snails, terrestrial gastropod mollusks in the infraorder Pupilloidei.
The Campaniloidea is a superfamily of sea snails, marine gastropod molluscs. The Campaniloidea are unassigned in the clade Caenogastropoda.
†Oriostomatoidea is an extinct superfamily of fossil sea snails, marine gastropod mollusks in the clade Neritimorpha.
Clavatulidae is a taxonomic family of sea snails, marine gastropod mollusks in the superfamily Conoidea. The family is not well differentiated morphologically.
Pseudomelaniidae is an extinct family of fossil sea snails, marine gastropod mollusks in the clade Caenogastropoda.
Craspedostomatidae is an extinct taxonomic family of fossil sea snails, marine, gastropod mollusks in the subclass Gastropoda incertae sedis, unassigned in the class Gastropoda.
Euomphaloidea, originally Euomphalacea, is an extinct superfamily of marine molluscs that lived from the Early Ordovician to the Late Cretaceous, included in the Gastropoda but speculated as instead perhaps Monoplacophora.
Frodospira is an extinct genus of Lophospiridae, a family of extinct sea snails, fossil marine gastropod mollusks. The genus is found in deposits of the Silurian age in Sweden. It was named in honor of the fictional character Frodo Baggins from J. R. R. Tolkien's The Lord of the Rings.
The taxonomy of the Gastropoda as it was revised in December 2017 by Philippe Bouchet and eight other authors, is a publication which lays out a newly revised system for the scientific classification of gastropod mollusks. The same work also included the taxonomy of monoplacophorans.
