Raphitoma diozodes Original image of a shell of Raphitoma diozodes Scientific classification Kingdom: Animalia Phylum: Mollusca Class: Gastropoda Subclass: Caenogastropoda Order: Neogastropoda Superfamily: Conoidea Family: Raphitomidae Genus: Raphitoma Species: †R. diozodes Binomial name †Raphitoma diozodes Cossmann, 1898

***Raphitoma diozodes*** is an extinct [species](/source/Species) of [sea snail](/source/Sea_snail), a marine [gastropod](/source/Gastropod) [mollusc](/source/Mollusc) in the [family](/source/Family_(taxonomy)) [Raphitomidae](/source/Raphitomidae).[1]

## Description

The length of the shell reaches 7.5 mm, its diameter 3 mm.

(Original description) The small shell has a narrow and slender shape. The rather long [spire](/source/Spire_(mollusc)) shows a conical shape. The [protoconch](/source/Protoconch) is polygynous, conoidal, with convex [whorls](/source/Whorl_(mollusc)) and a pointed [apex](/source/Apex_(mollusc)). The teleoconch contains six whorls. The first one is convex and finely ribbed. The others are biangular, the height of which exceeds half the width. They are separated by linear and wavy sutures, ornated with thick ribs, spaced apart, forming two knots crenellated by the two angles which share the height in three equal spaces. There is only spiral nets on the [body whorl](/source/Body_whorl), the two upper regions are smooth. The body whorl measures more than five-eighths of the total length. It is ovally attenuated at the base, on which sinuous ribs extend, crossed by an alternating reticulation, which tightens by winding around the [siphonal canal](/source/Siphonal_canal). The [aperture](/source/Aperture_(mollusc)) is very narrow, with almost parallel edges, truncated by the siphonal canal. The outer [lip](/source/Lip_(gastropod)) is straight. The [columella](/source/Columella_(gastropod)) is slightly callous and almost straight.[2]

## Distribution

Fossils of this extinct marine species were found in [Eocene](/source/Eocene) strata in Brittany, [France](/source/France)
