The shell of Baeopleuroceras is a short, rapidly expanding cyrtocone, curved through at least 90 degrees. The body chamber is one half the overall shell length. The siphuncle is subcentral with segments slightly expanded into the chambers.
Rhadinoceras and Nephriticeras are somewhat similar genera from within the Nephriticeratidae, except that in both the siphuncle is displaced between the center and the dorsum.
