Shells of Gasconsoceras are rapidly enlarging gyrocones and serpenticones covered by fine transverse and longitudinal striae and prominent dorsal and lateral transverse ribs. A fair degree of mobility is indicated by the deep hyponomic sinus. Other than being between center and venter, the siphuncle is poorly known.
