Type species: Goniatites looneyi Phillips, p. 236 [OD].

A:   Conch form like Anthracoceras.
G:   Branches of ventral lobe bifid; adventitious lobe irregularly subdivided.

[Judging from the neotype selected by MOORE, 1939, p.123 and officially confirmed by MOORE, 1958, p.222, the
type species seems to have closer affinities to Anthracoceratids than to Dimorphoceratids (MANGER, personal
communication)].
