Obornella is a genus of fossil sea snails, marine gastropod mollusks in the family Pleurotomariidae, the slit snails, (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).
Species within the genus Obornella include:
Archaeogastropoda was a taxonomic order of sea snails used in older classifications of gastropods, i.e. snails and slugs. Archeogastropoda are marine prosobranch gastropod mollusks, mainly herbivores, typically having two gills and a double-chambered heart, with the eggs and sperm discharged directly into the water. They were traditionally regarded as a relatively primitive group.
Pedicularia is a genus of small predatory or ectoparasitic sea snails, cowry-like marine gastropod molluscs in the family Ovulidae, the cowry allies.
Pleurotomariidae, common name the "slit snails", is a family of large marine gastropods in the superfamily Pleurotomarioidea of the subclass Vetigastropoda. This family is a very ancient lineage; there were numerous species in the geological past. The genus includes several hundred fossil forms, mostly Paleozoic. It is one of the oldest gastropod families, commencing in the Cambrian.
Ashfordia is a genus of small land snails, terrestrial pulmonate gastropod mollusks in the family Hygromiidae, the hairy snails.
Seguenzioidea is a superfamily of minute to medium-sized sea snails, marine gastropod mollusks in the clade Vetigastropoda.

Bayerotrochus boucheti is a species of sea snail, a marine gastropod mollusc in the family Pleurotomariidae.
Perotrochus tosatoi is a species of sea snail, a marine gastropod mollusk in the family Pleurotomariidae.
Bayerotrochus is a genus of sea snails, marine gastropod mollusks in the family Pleurotomariidae.
Mikadotrochus is a genus of sea snails, marine gastropod mollusks in the family Pleurotomariidae, the slit snails.
Lunella granulata, common name the granulated moon turban, is a species of sea snail, a marine gastropod mollusk in the family Turbinidae, the turban snails.
Lunella is a genus of sea snails, marine gastropod mollusks in the family Turbinidae, the turban snails.
