†Centrifugus is an extinct species of fossil sea snail, a marine gastropod mollusk in the family Euomphalidae, which paleontologists place in the order Archaeogastropoda.
This species was originally known from the Upper Silurian of northern Europe ( Gotland).
Description
The shell has a nearly flat spire, and is widest across the base, which is marked by a peripheral keel. The upper side of the aperture has a narrow slit, and a selenizone located close to the upper suture. Five strong spiral cords alternating with weaker ones cover the upper surface of the shell.
