Pseudoschloenbachia umbulazi, from Walaszczyk et al. (2014).

Belongs within: Desmoceratoidea.

The Muniericeratidae are an Upper Cretaceous (Lower Turonian to Lower Campanian) lineage of moderately involute ammonites (Wright et al. 1996).

Characters (from Wright et al. 1996): Moderately involute, with more or less fastigiate whorl section; generally with sinuous ribs tending to be tuberculate at umbilical and ventrolateral shoulders; midlateral tubercles may also occur. Suture with rather shallow and coarsely denticulate elements, the number of auxiliary lobes decreasing with time.
