This list of marine gastropod genera in the fossil record is an attempt to list all the genera of sea snails or marine gastropod mollusks which have been found in the fossil record. Nearly all of these are genera of shelled forms, since it is relatively rare for gastropods without a shell ( sea slugs ) to leave any recognizable traces.
†Nerinea is an extinct genus of fossil sea snails, marine gastropod molluscs in the clade Heterobranchia. Fossil record
Vermetus is a genus of sea snails, marine gastropod mollusks in the family Vermetidae, the worm snails or worm shells. [ 1 ] The genus Vermetus is very ancient: it occurs in the fossil record from the Jurassic to the Quaternary (age range: from 164.7 to 0.0 million years ago).
One variety of "Turritella agate", that from the Green River Formation in Wyoming, is a fossiliferous rock which does indeed contain numerous high-spired snail shells. However, contrary to the common name, these snails are not in the marine genus Turritella , instead they are freshwater snails in the species Elimia tenera , family Pleuroceridae ...
Bermuda land snails, scientific name Poecilozonites, are an endemic genus of pulmonate land snail in the family Gastrodontidae (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). 12 species are known from the fossil record, and 4 of these species (bermudensis, nelsoni, circumfirmatus, reinianus) survived into modern times, but due to the highly negative effects of human ...

Known from fossil evidence about 400,000 years old, it is one of many glacial relict species that remain in the Driftless Area, a glacier-eroded plateau that now makes up parts of Iowa, Illinois, Minnesota, and Wisconsin. Much of the area was covered by glaciers about 500,000 years ago, while parts of the Driftless Area were unglaciated.
The snail appears in fossil records dating between the Pliocene and Quaternary periods (between 3.6 and 0.012 million years ago). Fossilized shells have been found in Morocco, Italy, and Spain. [3] This sea snail is historically important because its hypobranchial gland secretes a mucus used to create a distinctive purple-blue indigo dye.
