The Purpurinidae are an extinct family of sea snails, marine gastropod molluscs in the order Neogastropoda. [1]
These sea snails lived between the Upper Permian or Lopingian (about 259 million years ago) and the Lower Cretaceous (about 112 million years ago). The fossils were found in Europe (Portugal, France, Luxembourg, Germany, Austria, Italy, Poland, Hungary, Slovenia and Romania), Asia (Israel, Jordan, Saudi Arabia, Iran, Pakistan, India and Japan), North America (Greenland, United States of America and Mexico) and Africa (Tunisia, Ethiopia, Kenya and Tanzania).

The following genera are recognsed in the family Purpurinidae: [1]
Heterobranchia, the heterobranchs, is a taxonomic clade of snails and slugs, which includes marine, aquatic and terrestrial gastropod mollusks.
Caenogastropoda is a taxonomic subclass of molluscs in the class Gastropoda. It is a large diverse group which are mostly sea snails and other marine gastropod mollusks, but also includes some freshwater snails and some land snails. The subclass is the most diverse and ecologically successful of the gastropods.
Sorbeoconcha is a taxonomic clade of snails, i.e. gastropods, mainly marine species with gills and opercula, within the clade Caenogastropoda.
Littorinimorpha is a large order of snails, gastropods, consisting primarily of sea snails, but also including some freshwater snails and land snails.
Melanopsidae, common name melanopsids, is a family of freshwater gastropods in the clade Sorbeoconcha. Species in this family are native to southern and eastern Europe, northern Africa, parts of the Middle East, New Zealand, and freshwater streams of some large South Pacific islands.
Thiaridae, common name thiarids or trumpet snails, is a family of tropical freshwater snails with an operculum, aquatic gastropod mollusks in the superfamily Cerithioidea.
Provannidae is a family of deep water sea snails, marine gastropod mollusks in the superfmaily Abyssochrysoidea.
Lithoglyphidae is a family of small freshwater snails with gills and an operculum, aquatic gastropod mollusks.
Vetigastropoda is a major taxonomic group of sea snails, marine gastropod mollusks that form a very ancient lineage. Taxonomically the Vetigastropoda are sometimes treated as an order, although they are treated as an unranked clade in Bouchet and Rocroi, 2005.
The Cerithioidea is a superfamily of marine, brackish water and freshwater gastropod containing more than 200 genera. The Cerithoidea are included unassigned in the subclass Caenogastropoda. The original name of this superfamily was Cerithiacea, in keeping with common superfamily endings at the time.
Ampullinidae are a mostly extinct taxonomic family of sea snails, marine gastropod molluscs in the clade Caenogastropoda.
Murchisonioidea is an extinct superfamily of small to large sea snails, marine gastropod mollusks in the clade Vetigastropoda.
Velutinoidea is a superfamily of sea snails, marine gastropod molluscs in the clade Littorinimorpha.
Pachychilidae, common name pachychilids, is a taxonomic family of freshwater snails, gastropod molluscs in the clade Sorbeoconcha.
Batillariidae, common name batillariids or mudcreepers, are a family of marine, cerithioidean gastropod molluscs in thesuperfamily Cerithioidea.
Scaliolidae, common name scaliolids, is a family of minute sea snails, marine gastropod molluscs or micromollusks in the superfamily Cerithioidea, the ceriths and their allies.
Abyssochrysoidea is a superfamily of deep-water sea snails, marine gastropod mollusks unassigned in the orderCaenogastropoda.
Conorbis is an extinct genus of sea snails, marine gastropod mollusks in the family Conorbidae.
Provanna sculpta is a species of sea snail, a marine gastropod mollusk in the family Provannidae.
Ampullinopsis is an extinct taxonomic genus of deep-water sea snails, marine gastropod molluscs in the clade Sorbeoconcha. These sea snails were epifaunal grazers. Sea snails of this genus lived from Paleocene epoch to Miocene epoch.
