Description
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.
Distribution
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.
