Most modern and fossil snail shells are dextrally coiled (right coiled), which means the aperture is on the right side of the axis of the shell when looking at the aperture. The word "nudibranch" comes from the Latin nudus "naked" and the Ancient Greek βράγχια ( bránkhia) "gills".

The fossil record of marine gastropods has been used as evidence to support the operation of species selection; namely, that species with limited dispersal differentially increase in numbers because they are more likely to speciate than widely dispersing species. This conclusion is based on a tacit phylogenetic assumption that ...Terrestrial gastropods became particularly common during the Palaeogene and it was probably at this time that shell-less gastropods also developed, but they are not found as fossils.

Here, we sequenced and assembled the complete mitochondrial genome of one representative species from ...The Class Gastropoda includes the groups pertaining to snails and slugs. The majority of gastropods have a single, usually spirally, coiled shell into which the body can be withdrawn. The shell of these creatures is often what is recovered in a fossil dig. Gastropods are by far the largest class of molluscs, comprising over 80% of all molluscs. The periostracum, as well as the coloration, is only rarely preserved in fossil shells. The apertural end of the gastropod shell is the anterior end, nearest to the head of the animal; the apex of the spire is often the posterior end or at least is the dorsal side. Most authors figure the shells with the apex of the spire uppermost. Fossils of Platyceras sp. from Floresta, Boyacá, Colombia.

Gastropods are the second largest class of animals (after the Insecta)—with 40,000–90,000 living species and at least 13,000 extant and fossil genera (Ponder and Lindberg, 2020)—and are also one of the most evolutionarily successful groups in the variety of ecosystems and habitats that they occupy. Most amateur fossil collectors identify fossils they find based on overall shape or by comparison to pictures. For some genera and species, this is fine, but for others, there may be similar-appearing possibilities, which require some understanding of the terminology used to scientifically describe the shapes, outlines, and specific features (parts) of gastropods.The number of fossil species is not known accurately, but is in the same order of magnitude and may range between 60,000 (a conservative guess, Taylor & Lewis, 2007) ...
