The Nephriticeratidae is a family of early Paleozoic (E-M Dev) nautilod cephalopods included in the Barrandeocerina (a suborder of tarphycerids sensu lato), distinguished by mostly cyrtoconic as well as gyroconic, sepenticontic, and sinstrally torticonic shells with large, typically straight necked (orthchoanitic) siphuncles. As for the suborder, connecting rings are thin.
