The shells of these fast-moving nektonic carnivores reach a diameter of about 40 millimetres (1.6 in). They are distinctively-ribbed, with windings that do not overlap largely each other. The suture lines are complicated and securely fastened to the shell wall.

Fossils of these ammonites have been found in
Tithonian-aged marine strata of Late Jurassic Russia, and in Cretaceous-aged marine-strata of Great Britain.
