Aletoceras is a genus of Oncocerida nautiloids from the middle Devonian of North America included in the family Brevicoceratidae.
The shell is a depressed brevicone, that is to say short. Sutures are generally straight, the siphuncle ventral, empty. The peristome (aperture rim) has a broad hyponomic sinus -for the hydrojet funnel, ventrolateral projections, dorsolateral sinuses - possibly for the eyes, and probably a mid dorsal sinus.
In general form, Aletoceras resembles Brevicoceras and , both also from the middle Devonian of North America.
The orientation of Aletoceras and others like it may have been vertical with the aperture facing down .
