Beudanticeras is an extinct cephalopod genus from the Cretaceous period belonging to the ammonoid subclass and included in the family Desmoceratidae

Desmoceratidae

Desmoceratidae is a family belonging to the ammonite subclass. They are an extinct group of ammonoids, shelled cephalopods related to squid, belemnites, octopuses, and cuttlefish, and more distantly to the nautiloids.-References:* accessed on 10/01/07...

.

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 umblicus. The shell is generally smooth but may have weak ribs but no tubercles. The suture is ammonitic.
