Acrimeroceras has a shell like that of Paratornoceras with biconvex growth lines and constrictions and simple dorsal lobe. The adult shell is extremely compressed, smooth, oxyconic to lanceolate in section. Early growth stages are depressed, subglobular, smooth or ribbled, with an open umbilcus and rounded to suboxyconic venter, which sharpens relatively early during ontogeny. Sutural elements in general are broadly rounded except for the lateral lobe which is pointed and asymmetric.
