Quebecoceras is a cyrtoconic, similar to Dakeoceras and Paradakeoceras except for having a circular cross section and more persistent curvature and rate of expansion. Paradakeoceras differs in having a somewhat flattened venter.
The only known species, Quebecoceras quebecense, is half again a large as the largest known Dakeoceras, making it a fairly large ellesmeroceratid genus.
