Desmocerataceae is a superfamily of Cretaceous ammonites, generally with round or oval-whorled shells that are mostly smooth or weakly ribbed and rarely tuberculate, but commonly with constrictions.[1] [2] Regarded as monophyletic, the Desmocerataceae are derived from the Phylloceratidae, spltting off in the Early Cretaceous (Valanginian) and persisting to the end of the Maastrichtian.
