''Flemingites'' is a genus of evolute

ammonoid Ammonoids are a group of extinct marine mollusc animals in the subclass Ammonoidea of the class Cephalopoda. These molluscs, commonly referred to as ammonites, are more closely related to living coleoids (i.e., octopuses, squid and cuttlefish) ...

s from the Lower Triassic with spiral ridges on the shell.

Diagnosis

The shell of ''Flemingites'' is evolute so that all whorls show externally. Whorls are robust, slightly embracing, usually a little higher than wide and increasing very slowly. The venter (outside rim) is somewhat flattened and usually much narrower that the widest part of the whorl. Strong, always single, lateral ribs are confined to the sides. Fine spiral ridges typically cover the shell, found even in casts. The suture is distinctly ceratitic with rounded entire saddles and deep serrated lobes.
