Ophiceratidae
Introduction The '''Ophiceratidae''' is a family in the ammonoid order Ceratitida from the Lower Triassic, previously included in the '''Otocerataceae''' but now placed in the '''Noritiaceae''' as revised.The Ophiceratidae produced sepenticones with compressed elliptical whorl sections in which the venter is generally rounded and ornamentation is usually weak. The suture is simple, ceratitic.Named genera include  ''Ophiceras'', the type, ''Discophiceras'', ''Nordophiceras'', ''Sakhaites'', ''Vishnuites'', and ''Wordieoceras''.The phonetically similar Ophioceratidae of Strand 1934 is synonymous with Ophidioceratidae Hyatt, 1894a family in the nautiloid cephalopod order, Tarphycerida.
