Gaetanoceras:

Like Agathiceras, but ornamentation consisting of delicate growth lines only.

[Character of spiral ornamentation is regarded by some authors of specific rather than generic significance].

[Leonova 1989, p. 113]: Conch pachycone, completely involute, umbilicus extremely tight. Sculpture represented by thin radial
lamellae, which form a slight sinus on venter. Suture line consists of a wide, bifid ventral lobe, three simple external
lateral, one inner lateral and a dorsal lobe.
