A variety of fossil gastropods occur in the ...Gastropods (formally, Gastropoda) make up a large group (class) of molluscs. They have a muscular foot, eyes, tentacles and a special rasp-like feeding organ called the radula, which is composed of many tiny teeth. Most gastropods have a coiled or conical shell, which may be extremely reduced in some species or lost entirely as in slugs.

The class is made up of the snails, which have a shell into which the animal can withdraw, and the slugs, which are snails whose shells have been reduced to an internal fragment or lost.Gastropod - Shell Structure, Anatomy, Diversity: The typical snail has a calcareous shell coiled in a spiral pattern around a central axis called the columella.
