Anomphalus jaggerius is an extinct species of Permian sea snail. Fossils have been found in Artinskian era limestone from the Bird Spring Formation in the southern Arrow Canyon Range of the US State of Nevada. The species, which had a shell 6.37 millimetres (0.251 in) wide, was a subtidal epifaunal grazer. [1]
Pleurotomariidae, common name the "slit snails", is a family of large marine gastropods in the superfamily Pleurotomarioidea of the subclass Vetigastropoda. [1] This family is a very ancient lineage; there were numerous species in the geological past. The genus includes several hundred fossil forms, mostly Paleozoic.
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.
Archaeostylus manukauensis is an extinct species of flax snail, a large air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Bothriembryontidae. [ 2 ] This species is the typetaxon and only member of the monotypic genus Archaeostylus , found in Pliocene age sediments of northern New Zealand .
Holopea is an extinct genus of fossil sea snails, Paleozoic gastropod mollusks in the family Holopeidae. [1]These molluscs were stationary epifaunal suspension feeders. They lived in the Paleozoic Era, Ordovician Period, upper Arenigian age (between 478.6 ± 1.7 and 471.8 ± 1.6 million years ago) to the Carboniferous period, lower Serpukhovian age (from 328.3 (± 1.6) Ma to 318.1 (± 1.3) mya).
The fossil examined in the study, collected during a 2011 expedition by the Antarctic Peninsula Paleontology Project, was found encased in rock that dated back 68.4 to 69.2 million years and ...

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).
