Gemmellaro 1887
Adrianites is an extinct ammonoid genus named by Gemmellaro, 1887, that lived during the Permian. The type is Adrianites elegans Gemmellaro, 1887.
The shell is somewhat small, (less than 70 mm. in diameter) and thickly subdiscoidal to subglobular with a small umbilicus and surface usually covered by longitudinal lirae. Growth-lines are nearly straight and generally prominent. Sutures form 16 to 30 lobes, the ventral lobe bifid, its prongs (secondary lobes) curved and much shorter and narrower than the first lateral lobes. Transverse constrictions are present at least on the internal mold. Fully mature specimens often have constricted apertures with a ventral salient and ventro-lateral projections on the margins.
Aricoceras, Doryceras, Neocrimites, and Palermites are among related genera'
