The flanks and venter are flattened, the flanks converge on the dorsum, the venter has a shallow median groove. The suture is with rounded ventral and lateral lobes. The siphuncle is small, tubular, and subcentral. (Kummel 1964, K413) ''Cooperoceras'', known from the Lower Permian of N America and Europe (Urals), was named by Miller in 1945. The genotype is ''Cooperoceras texanum''.
