subclass and included in the family Desmoceratidae. ''Beudanticeras'' has a rather to very compressed shell that is moderately involute, with convex to flat sides and a narrowly arched out rim. Coiling is such that the outer whorl embraces much of the next inner whorl, leaving a small spiraled umbilicus. The shell is generally smooth but may have weak ribs but no tubercles. The suture is ammonitic. The derivation of ''Beudanticeras'' may be from '' Uhligella'', although ''Uhligella'' is partly contemporary with early ''Beudanticeras''. Other related genera include '' Beudantiella'', '' Brewericeras'', '' Zurcherella'', and possibly '' Pseudosaynella''.
