Murchisoniidae is an extinct family of fossil gastropods in the superfamily Murchisonioidea (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). [1]
Family is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy; it is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as being the "walnut family".
A fossil is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnants. The totality of fossils is known as the fossil record.
Murchisonioidea is an extinct superfamily of small to large sea snails, marine gastropod mollusks in the clade Vetigastropoda.
This family has no subfamilies.
Genera within the family Murchisoniidae include:
The Bellerophontidae are an extinct family of specialized globose bellerophontids, Paleozoic and early Triassic mollusks of the class Gastropoda.
Helicinidae is a family of small tropical land snails which have an operculum. They are terrestrial operculate gastropod mollusks in the superfamily Helicinoidea.
Neritidae, common name the nerites, is a taxonomic family of small- to medium-sized saltwater and freshwater snails which have a gill and a distinctive operculum.
Thiaridae, common name thiarids or trumpet snails, is a family of tropical freshwater snails with an operculum, aquatic gastropod mollusks in the superfamily Cerithioidea.
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.
Liotiidae is a family of small sea snails, marine gastropod mollusks in the clade Vetigastropoda.
Eucyclidae is a family of gastropods in the superfamily Seguenzioidea.
Amberleyoidea is a superfamily of extinct, small to large sea snails, marine gastropod mollusks in the clade Vetigastropoda.
Eotomarioidea is an extinct superfamily of small to large sea snails, marine gastropod mollusks in the clade Vetigastropoda.
†Oriostomatoidea is an extinct superfamily of fossil sea snails, marine gastropod mollusks in the clade Neritimorpha.
Sinuitidae is an extinct family of Paleozoic molluscs of uncertain position. They had isostrophically coiled shells.
Lesueurillidae is an extinct family of paleozoic molluscs (gastropods?) with anisostrophically coiled shells of uncertain position (Gastropoda?).
Isospiridae is an extinct family of fossil sea snails, Paleozoic gastropod mollusks.
The †Raphistomatidae is a taxonomic family of fossil sea snails, Paleozoic marine gastropod mollusks. This family was established by Koken in 1896. This family is found in the fossil record from the Upper Cambrian to the Middle Permian.
Lophospiridae is an extinct taxonomic family of sea snails, marine gastropod molluscs.
†Oriostomatidae is an extinct taxonomic family of fossil sea snails, marine gastropod mollusks in the clade Neritimorpha.
Comitas aequatorialis is a species of sea snail, a marine gastropod mollusc in the family Pseudomelatomidae, the turrids and allies.
Crassispira integra is a species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae.
Filodrillia dolorosa is a species of sea snail, a marine gastropod mollusk in the family Borsoniidae.
