  Aipoceras is a genus of loosely coiled aipoceratid nautiloids with laterally compressed whorls; shells expanding moderately to fairly rapidly with a tendency to uncoil at maturity. Juvenile forms are somewhat cyrtoconic. The apical end forms a hook. Aipoceras has been found in Lower Mississippian strata in the U.S.
