The Hungaritidae comprises a family of ceratitid ammonites described in the Treatise,(Arkell et al. 1957), as involute compressed, discoidal, with keeled or sharpened venter, smooth to weakly costate. Sutures ceratitid, usually with numerous elements. Hungaritids are Middle Triassic in age spanning a range from about 247 Ma to 235 Ma. By current assessment six genera are included. :''Hungarites'', type genus :''Gevanites'' :''Iberites'' :''Negebites'' :''Paraceratitoides'' :''Perrinoceras'' Arkell, et al. 1957, in Part L of the original treatise lists instead: ''Hungarites'', ''Noetlingites'', ''Longobardites'', ''Neodalmanites'', ''Groenlandites'', ''Perrinoceras'', ''Arctohungarites'', ''Dalmanites'', and ''Prohungarites''. Only two have remained, Hungarites and Perrinoceras. ''Longobardites'' has been removed as type genus for the Longobarditidae, along with ''Arctohungarites'', ''Groenlandites'', and ''Noetlingites''. ==''References''== *Arkell, et al., 1957.
