"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."@en . "1426"^^ . . .
