Type species: Turritella decussata von Münster, 1841 , original designation; Late Triassic , North Italy .

Diagnosis.—“The turriculate shell has a major keel on the first whorls of the teleoconch, which disappears on later whorls as they become almost flat. The spiral sculpture is crossed by few collabral elements. The protoconch has a smooth surface, and the embryonic shell is immersed in its apex. In the larval whorls the sinistral coiling changes into dextral coiling before onset of the teleoconch. With transition from larval to adult shell sculpture and whorl shape change drastically” ( Bandel 1995: 21).
Stratigraphic and geographic range.—Late Triassic to Pliensbachian; England,? France, North Italy.
