Nautilaceae

Nautilaceae, de Blainville 1825, is a superfamily within the Nautilida with a range extending from the Upper Triassic to Recent, having generally smooth involute shells, some with sinuous plications or ribs. Whorl sections vary from compressed to depressed, sutures from straight to strongly sinuous, siphuncle central or dorsal in position.

The Nautilaceae have their origin in the Syringonautilidae, a family within the Trigonocerataceae restricted to the Triassic.

Six families are included in the Nautilaceae, the Nautilidae, Paracenoceratidae, Pseudonautilidae, Cymatoceratidae, Hercoglossidae, and Aturiidae.
