The Episageceratinae, proposed by Ruzhencev, 1956, is based on the genus ''Episageceras'' previously included in the subfamily Medlicottiinae and lived during Late Permian and Early Triassic times. So far only three confirmed genera are included: ''Episageceras'', ''Latisageceras'', and ''Nodosageceras''. The type genus, ''Episageceras'', named by Noetling 1904, is defined in the Treatise (L74) as like ''Medlicottia'' but with a broader shell and sutures with a smaller second lateral lobe. ''Latisageceras'' and ''Nodosageceras'' named by Ruzhencev 1956 are based on species of ''Episageceras''. J.P Smith, 1932 (USGS PP 167) included ''Episageceras'' in the Pronoritidae (p. 36) as a subgenus of ''Medlicottia''. ==''References''== ;Notes ;Bibliography * ( Goniat >Prolecanitina ) 11/07/11 * Treatise on Invertebrate Paleontology Part L (Ammonoidea).
