Reticuloceratidae is one of five families of the Gastrioceratoidea superfamily. They are an extinct group of ammonoid, which are shelled cephalopods related to squids, belemnites, octopuses, and cuttlefish, and more distantly to the nautiloids.

Aphantites
''Aphantites'' is a Lower Pennsylvanian ammonite Ammonoids are a group of extinct marine mollusc animals in the subclass Ammonoidea of the class Cephalopoda. These molluscs, commonly referred to as ammonites, are more closely related to living coleoids (i.e., octopuses, squid and cuttlefish) ... belonging to the goniatitid family Reticuloceratidae which are characterized by involute subdiscoidal shells covered by linear or biconvex growth lines that may be crossed by longitudinal lirae, producing a reticulate pattern. Sutures are simple, the ventral lobe double pronged. Related genera include '' Surenites'' and '' Reticuloceras''.

Description ''Quinnites ''can be recognized by its thickly discoidal shell with a wide umbilicus and double pronged ventral lobe with a median saddle about half as high as the entire lobe. Umbilical ribs are common. May have spiral ornamentation, constrictions, or ventral groove. Taxonomy ''Quinnites'', named by Manger and Saunders 1980, contains two species, ''Quinnites henbesti'' and ''Quinnites textum'', both removed from Gastrioceras ( Branneroceras).

Arkanites
''Arkanites'' is a goniatitid ammonite that lived during the Early Pennsylvanian that has been found in Arkansas and Oklahoma in the U.S. Morphology The shell of ''Arkanites'' is subglobose, rather evolute, with a moderately wide umbilicus and a broadly rounded venter (or rim). Sculpture consists of well developed umbilical ribbing, sometimes with nodelike bases, and broad, deep, ventrolateral grooves. The ventral lobe of the suture, which sits on the outer rim, is large, with a median saddle that exceeds half its overall height. The first lateral saddle is broadly rounded, the adventitious lobe is large and pointed. Taxonomy ''Arkanites'' is possibly derived from '' Retites'' and closely related to '' Quinnites'', all which come from the Lower Pennsylvanian (Morrowan The Bashkirian is in the International Commission on Stratigraphy, ICS geologic timescale the lowest stage (stratigraphy), stage or oldest age (geology), age of the Pennsylvanian (geology), Pennsylvanian.

Gastrioceratoidea
Gastrioceratoidea is one of 17 superfamilies in the suborder Goniatitina, ammonoid cephalopods from the Late Paleozoic. Shells are variable in form with a broad whorl section and wide umbilicus. Early whorls are commonly evolute. Shells may be smooth or sculptured with transverse striae (fine grooves) and constrictions. The ventral lobe of the suture is double pronged, prongs being relatively wide but sides not diverging. The median saddle is half as high or more so than the height of the entire ventral lobe. The first lateral saddle, which lies next to the ventral lobe is either rounded or subacute. Gastrioceratoideae lived during the middle part of the Carboniferous The Carboniferous ( ) is a geologic period and system of the Paleozoic that spans 60 million years from the end of the Devonian Period million years ago ( Mya), to the beginning of the Permian Period, million years ago.
