The shell is compressed with the outer whorl covering much of the previous. Sides are slightly convex, converge toward a narrowly ached venter. Inner whorls have sharp falcoid ribs, outer are smooth. Umbilical tubercles are lacking. Similar related forms include ''Neosaynella'' and ''Cleoniceras''. ''Aioloceras'' has been found in Albian (uL Cret) sediments in Madagascar, Patagonia, and possibly Queensland. ==References== Mesozoic Ammonoidea, Arkell ''et al''; Treatise on Invertebrate Paleontology, Part L.
