Crassispira mausseneti is an extinct species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae, the turrids and allies.[1]

Description

The length of the shell attains 5 mm and a diameter of 2 mm. It lived in marine environments.[2]

"Small, short shell, with a conoid and obtuse apex, composed of slightly convex whorls, slightly excavated at the back, separated by a suture accompanied by a prominent and almost smooth rim, adorned with small curved ribs crenellating four prominent cords and giving the surface a rough appearance that persists on the last whorl; this is almost equal to half the length, attenuated at the base, which bears four or five smooth and spaced keels, crossed by fine and sinuous folds; opening small, rounded; canal wide and short, barely inflected."[3]

Distribution

Fossils have been found in Eocene strata in the Paris Basin, France.
