Shelbyoceras is a genus of Cambrian molluscs which was one of the genera mistaken for a cephalopod, since the characteristics differentiating monoplacophora from cephalopods are few. Shelbyoceras was reclassified based on a depressed groove that forms a band around the shell, which is similar to a feature seen in Hypseloconus[2] (with whom it may be synonymous).[3] The septa in this genus are either closely or irregularly spaced.[2]
