Goniatitoidea . formerly Goniatitaceae in older publications, is a superfamily of late Paleozoic ammonoid cephalopods included in the Goniatitida. They are characterized by thinly discoidal to globular shells with variable umbilici and sculpture. The ventral lobe, located along the outer margin, is prominently bifurcated (two pronged); the lateral lobe undivided.
