:Interestingly, the nautilids were not affected by the wave of extinctions at the Cretaceous - Tertiary boundary which wiped out their close relatives, the ammonoids; three families and at least five genera of nautilids crossed this boundary and the [[Paleocene]] and [[Eocene]] saw a resurgence of nautilids, with several new genera added, most of which were of worldwide distribution (Miller, 1949; Kummel, 1956; Shimanskiy, 1979).

The Nautilida contains five superfamilies, four are  late Paleozoic, of which three extend into the Triassic, one is Jurassic to Recent. They are the: <br>

:: `-Rutoceratidae (--> Aipocerataceae, Clydonautilaceae, Trigoncerataceae.)

:[[Clydonautilaceae]] <br>

:[[Aipocerataceae]] <br>

:[[Nautilaceae]]
-
:: [[Clydonautilaceae]]

The older and longer established --aceae endings are retained as they more clearly indicate superfamily rank than does the now more ambiguous --oidea ending  which in invertebrate science had been an indication of subclass or superorder.

Shimanskiy (1962) divided the Nautilida into 34 families (later (1979) reduced to 30) and 184 genera, whilst Kummel in the ''Treatise'' (1964) recognized 24 families and 165 genera. Both agree that the Nautilida is the largest order of the (sensu lato) [[Nautiloidea]].
