Flemingites is an extinct genus of evolute, ceratitic ammonoid from the Smithian portion of the Olenekian age (Lower Triassic Period) with spiral ridges on the shell.
The shell of Flemingites is evolute so that all whorls are externally visible. The whorls are robust, slightly embracing, and usually a little higher than wide and the whorl expansion rate is apparently very slow. The venter (outside rim) of the shell is somewhat flattened and usually much narrower that the widest part of the whorl.
Strong, always single, lateral ribs are confined to the sides of the shell. Fine spiral ridges typically cover the shell as well and can be found even on casts of this genus. The suture is distinctly ceratitic: with rounded entire saddles and deep serrated lobes.[1]
