''Trigonoceras'' has a very loosely coiled gyroconic or cyrtoconic shell with a subtriangular cross section, as indicated by fragmentary specimens. The venter on the outer rim or convex side is broad and transversely concave with angular shoulders; the sides which converge on a narrow dorsum are broadly convex. The siphuncle is slightly dorsal of the center and is orthochoanitic.(,B.1964.) A member of the Trigonoceratidae, ''Trigonoceras'' is also a component of the superfamily Trigonocerataceae ==References== * ,B.1964.
