Anadesmoceras is an hoplitid ammonite from the lower Albian (upper Lower Cretaceous) of England, included in the subfamily Cleoniceratinae. Anadesmoceras has a shell shaped more or less like a compressed Cleoniceras but with faint ornament only on the inner whorls. The shell has bundled growth striae. The aperture is preceded by several wide sinuous constrictions.
