Flemingites
Flemingites is an extinct genus of evolute ammonoid from the Smithian 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 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.
Taxonomic position
included Flemingites in the Xenodiscidae, which was included in the superfamily Prolecanitoidea. Later it was reassigned to the Flemingitidae and Noritaceae as shown in part L of the American TreatiseOther classifications put Flemingites in the Meekocerataceae, or as recently renamed, Meekoceratoidea.
