Pseudohaploceras

Pseuohaploceras is a genus of desmosceratid ammonites from the Lower Cretaceous. The genus is distinguished by its moderately involute, slightly to moderately compressed shell with convex sides and regular straight or sinuous constrictions between which are fairly fine, distinct, sharp or rounded branching ribs extending from the umbilical edge and crossing the venter, the outer rim.

Pseudohaploceras is considered an offshoot of early Valdedorsella, which differ in having a more broadly rounded whorl section and generally straight radial constrictions. It is included in the subfamily Pizosiinae.
